We apologize for any inconvenience this may cause. Interpreting Central Venous Pressure Waveforms, by Dr. James DiNardo. Hi. My name is Jim DiNardo. I'm a Professor of Anesthesia at Harvard Medical School and one of the Cardiac ICU attendings here at Children's Hospital Boston. I'm going to talk now about our central venous pressure trace and the kind of information that we can get from a central venous pressure trace, and also about how a central venous pressure trace is generated and what implications that has. So again, it's important to remember that when we're measuring a CVP, we are in fact measuring a pressure in the central circulation, so in the superior vena cava or in the right atrium, depending on where the tip of the catheter is. But in fact, what's happening is this pressure is a consequence physiologically of volume changes in the superior vena cava or the right atrium in the setting of the compliance of those two systems. What we see here when we look at a CVP trace, we see a volume moving in and out of the right atrium or the superior vena cava being represented as a pressure here. This pressure -- we're going to talk about this trace as one bead of the central venous pressure. You can see that there's a couple of waves here. So this first wave on the upstroke here is known as the A wave. And you can see that is actually occurring - we can see with the simultaneous A line trace - as a late event in diastole. So here is end diastole in the arterial blood pressure traced right before the onset of systole. And if we look up here at the EKG, that same interval corresponds with the atrial contraction of the EKG. So this is an end diastolic event. And what this represents-- this is the pressure generated in the right atrium or the superior vena cava when the atrium contracts in a late diastole. And that is the pressure that's generated. And that pressure is a consequence of the volume of blood that's moving into the atrium and the compliance of the atrium. So you can imagine a circumstance where, if you have a very compliant right atrium, even if you have a lot of volume moving in with the atrial contraction, the A wave is not going to be very big. By the same token, if I have a very non-compliant right atrium, a very young patient, and I have a lot of volume moving - and let's say they've been given a big volume infusion - and I have a very forceful atrial contraction, I'm going to see a big A wave here. The next part of this CVP waveform is a C wave. You can see with a simultaneous A line trace that the C wave of occurs during the onset of ventricular systole. And if we look up here at the EKG, that same time interval corresponds to the R wave. What the C wave represents is bowing of the tricuspid valve back into the right atrium during systole such that there is a transient decrease in the atrial compliance and an increase in atrial pressure. During tachycardia, the C wave commonly becomes merged with the A wave. And under those circumstances, it's almost impossible to differentiate the A and the C waves. This little down slope is known as the x descent. And the x descent actually represents-- we're going to be talking about systole now here. See, now we're under the systolic portion of the arterial line trace and we're into the QRS of the EKG. And it also represents a combination of factors. It represents the atrium relaxing. And as a consequence of that, the tricuspid valve apparatus is descending towards the apex of the ventricle. And that, in turn, results in the formation of this x descent. Now, the next thing we see here is the V wave. And every human being that has a CVP line in has a V wave. The V wave is a late systolic event. You can see with the simultaneous A line trace that the V wave is occurring during late systole. And again, if we look up here at the EKG, this interval corresponds to the T wave of the EKG.

Bernoulli's principle 3d animation
 
03:25
Bernoulli's principle 3d animation This is an important principle involving the movement of a fluid through a pressure difference. Suppose a fluid is moving in a horizontal direction and encounters a pressure difference. This pressure difference will result in a net force, which by Newton's 2nd law will cause an acceleration of the fluid. The fundamental relation,which is known as Bernoulli's principle. This is very similar to the statement we encountered before for a freely falling object, where the gravitational potential energy plus the kinetic energy was constant (i. e., was conserved). Bernoulli's principle thus says that a rise (fall) in pressure in a flowing fluid must always be accompanied by a decrease (increase) in the speed, and conversely, if an increase (decrease) in , the speed of the fluid results in a decrease (increase) in the pressure. This is at the heart of a number of everyday phenomena. As a very trivial example, Bernouilli's principle is responsible for the fact that a shower curtain gets ``sucked inwards'' when the water is first turned on. What happens is that the increased water/air velocity inside the curtain (relative to the still air on the other side) causes a pressure drop. The pressure difference between the outside and inside causes a net force on the shower curtain which sucks it inward. A more useful example is provided by the functioning of a perfume bottle: squeezing the bulb over the fluid creates a low pressure area due to the higher speed of the air, which subsequently draws the fluid up. This is illustrated in the following figure.

All rights reserved. Voice by: Sue Stern. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, and vice versa. For example, during physical exercises, the heart beats faster to put out more blood in response to higher demand of the body. It is noteworthy that the ventricles do NOT eject ALL the blood they contain in one beat. In a typical example, a ventricle is filled with about 100ml of blood at the end of its load, but only 60ml is ejected during contraction. This corresponds to an EJECTION fraction of 60%. The 100ml is the end-DIASTOLIC volume, or EDV. The 40ml that remains in the ventricle after contraction is the end-SYSTOLIC volume, or ESV. The stroke volume equals EDV minus ESV, and is dependent on 3 factors: contractility, preload, and afterload. Contractility refers to the force of the contraction of the heart muscle. The more forceful the contraction, the more blood it ejects. PRELOAD is RELATED to the end-diastolic volume. Preload, by definition, is the degree of STRETCH of cardiac myocytes at the end of ventricular filling, but since this parameter is not readily measurable in patients, EDV is used instead. This is because the stretch level of the wall of a ventricle INcreases as it’s filled with more and more blood; just like a balloon - the more air it contains, the more stretched it is. According to the Frank-Starling mechanism, the greater the stretch, the greater the force of contraction. In the balloon analogy, the more inflated the balloon, the more forceful it releases air when deflated. AFTERLOAD, on the other hand, is the RESISTANCE that the ventricle must overcome to eject blood. Afterload includes 2 major components: - Vascular pressure: The pressure in the left ventricle must be GREATER than the systemic pressure for the aortic valve to open. Similarly, the pressure in the right ventricle must exceed pulmonary pressure to open the pulmonary valve. In hypertension for example, higher vascular pressures make it more difficult for the valves to open, resulting in a REDUCED amount of ejected blood. - Damage to the valves, such as stenosis, also presents higher resistance and leads to lower blood output.

DESCRIPTION: We recently did a complete unboxing and review of the amazing T6 ECG+PPG fitness/health band here: https://www.youtube.com/watch?v=XnDKjJUgLRE This is a quick update to show you the improved screen on a production unit compared to the prototype we had available for initial review. The new one is way brighter and fully usable indoors and in the shade outdoors. As you may recall, this band, by combining the real time readings from the two forms of biometric measurements, the ECG electrical signal from the metal plates and the PPG optical readings from the green diodes, and using advanced internal algorithms, something called a PWTT (see the last part of the video for more on this) can compute your blood pressure and your HRV (that’s Heart Rate Variability). Want more technical details about this? Then try: scholar.google.com and search for: ECG+PPG ECG+PPG HRV ECG+PPG TWTT Here are some reference documents from these searches worth reviewing: Pulse Wave Transit Time and Its Relationship with Systolic Blood Pressure https://link.springer.com/chapter/10.1007/978-3-642-14515-5_345 Mobile cardiac health monitoring Patent Application WO 2014042845 A1 https://www.google.com/patents/WO2014042845A1?cl=en NOTE: For the serious health enthusiasts, here’s a new health band offering unique new biometric measurements of skin humidity, proximity temperature, and the delta, or difference, between actual skin temperature and close proximity wrist temperature. The reason for this appears to be that, by monitoring the spread between your actual skin temperature and the close surrounding air temperature (not the ambient temperature, but the temperature near your body), the band can warn you when you are “too hot” or “too cold” and should take some action to change your body condition. It also tracks these measurements in a series of graphs on the tethering app for you to analyze in detail later. Interested?

USMLE Renal 3: Nephron Anatomy, Physiology and TF/P Graphs
 
24:42
Welcome to LY Med, where I go over everything you need to know for the USMLE STEP 1, with new videos every day. Follow along with First Aid, or with my notes which can be found here: https://www.dropbox.com/sh/mt1jrikc24022py/AADNAVG8cAj4Su7xFO74fLBka?dl=0 This video is on the anatomy and physiology of the nephron. This is the functional unit of the kidneys! The nephron is made of the Bowman's capsule, proximal convoluted tubule, Loop of henle, distal convoluted tubules and collecting duct. This nephron is fed by the afferent arteriole. As you know, arterioles become capillaries and that's exactly what it does! It forms a bundle of capillaries called the glomerulus before eventually becoming the efferent arteriole and peritubular capillaries. But back to the anatomy of the nephron! Proximal convoluted tubule: the powerhouse of the nephron. It's the first line unit and reabsorbs most of the things in our urine, including glucose, amino acids, phosphate, and most of our sodium. It reabsorbs sodium via the Na/H+ pump which is facilitated by carbonic anhydrase. Angiotensin II revs up this pump and helps us reabsorb more sodium and increase blood pressure. It also has a strong endocrine function by reabsorbing 1 alpha hydroxylase. Thin descending limb can't reabsorb sodium but loves to take in water. Thick ascending limb is the complete opposite! Here, it can't take in water, but loves to take in solutes via the Na/K/Cl channel. Something you should know, sometimes potassium backleaks and pushes calcium and magnesium paracellularly and helps us reabsorb these too! Distal convoluted tubule; here urine is the most dilute. It reabsorbs salt as well as calcium! Collecting duct: here you have alpha intercalated cells: these secrete acid. Also you have the ENAC channel that helps reabsorb sodium in exchange for potassium and hydrogen! Aldosterone increases these channels which can result in hypokalemia and alkalosis. However, in hypoaldosteronism, you get salt wasting with hyperkalemia and acidosis! Another hormone works on here in the form of ADH! This works on V2 receptors which increase water channels aka aquaporin channels. Now to balance out the high water reabsorption, our thick ascending limb increases it's solute uptake and urea. That does it for normal anatomy. Now let's talk about some physiology, in particular TFP graphs! Now to preface it, we reabsorb things at different rates when compared to water. For example, we reabsorb electrolytes at the same rate as water. Meanwhile there are some things like glucose and amino acids faster than water. Conversely, we have things we dont want to reabsorb! We can tell the difference via the TFP graph. When TFP = 1, then we reabsorb things at the same rate as water. E.g. is electrolytes. When TFP is less than 1, then this is bicarb, glucose, amino acids. That's it! See you next time.

The Cardiac Cycle, Animation

Phases of the cardiac cycle. This video and other related images/videos (in HD) are available for instant download licensing here: https://www.alilamedicalmedia.com/-/galleries/images-videos-by-medical-specialties/cardiology-and-vascular-diseases ©Alila Medical Media. All rights reserved. Voice by: Sue Stern. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The cycle is initiated with the firing of the SA node that stimulates the atria to depolarize. This is represented by the P-wave on the ECG. Atrial contraction starts shortly after the P-wave begins, and causes the pressure within the atria to increase, FORCING blood into the ventricles. Atrial contraction, however, only accounts for a FRACTION of ventricular filling, because at this point, the ventricles are ALREADY almost full due to PASSIVE blood flow DOWN the ventricles through the OPEN AV valves. As atrial contraction completes, atrial pressure begins to FALL, REVERSING the pressure gradient across the AV valves, causing them to CLOSE. The closing of the AV valves produces the first heart sound, S1, and marks the beginning of SYSTOLE. At this point, ventricular depolarization, represented by the QRS complex, is half way through, and the ventricles start to contract, RAPIDLY building UP pressures inside the ventricles. For a moment, however, the semilunar valves remain closed, and the ventricles contract within a CLOSED space. This phase is referred to as isovolumetric contraction, because NO blood is ejected and ventricular volume is UN-changed. Ventricular ejection starts when ventricular pressures EXCEED the pressures within the aorta and pulmonary artery; the aortic and pulmonic valves OPEN and blood is EJECTED out of the ventricles. This is the RAPID ejection phase. As ventricular repolarization, reflected by the T-wave, begins, ventricular pressure starts to FALL and the force of ejection is REDUCED. When ventricular pressures drop BELOW aortic and pulmonary pressures, the semilunar valves CLOSE, marking the end of systole and beginning of diastole. Closure of semilunar valves produces the second heart sound, S2. The first part of diastole is, again, isovolumetric, as the ventricles relax with ALL valves CLOSED. Ventricular pressure drops RAPIDLY but their volumes remain UNchanged. Meanwhile, the atria are being filled with blood and atrial pressures RISE slowly. Ventricular FILLING starts when ventricular pressures drop BELOW atrial pressures, causing the AV valve to open, allowing blood to flow DOWN the ventricles PASSIVELY.

DESCRIPTION: This is the smartwatch version of the various ECG+PPG smart health/fitness bands we have reviewed recently. By combining the real time readings from the two forms of biometric measurements, the ECG electrical signal from the metal plates and the PPG optical readings from the green diodes, and using advanced internal algorithms, something called a PWTT (see the last part of the video for more on this) can be computed to calculate your blood pressure and your HRV (that’s Heart Rate Variability) with, again, the claimed high accuracy. This video also shows a feature update to the WearHeart tethering phone app that enhances the report for Heart Rate Variability (HRV). More ECG+PPG Wearables: https://www.youtube.com/watch?v=XnDKjJUgLRE&list=PLGZLicZ6A2vXkXWLguX0WPFgEDbpIbt2u NOTE: For the serious health enthusiasts, here’s a new health band offering unique new biometric measurements of skin humidity, proximity temperature, and the delta, or difference, between actual skin temperature and close proximity wrist temperature. The reason for this appears to be that, by monitoring the spread between your actual skin temperature and the close surrounding air temperature (not the ambient temperature, but the temperature near your body), the band can warn you when you are “too hot” or “too cold” and should take some action to change your body condition. It also tracks these measurements in a series of graphs on the tethering app for you to analyze in detail later. Interested?

How To lower Blood Pressure Naturally With Nattokinase And Exercise
 
13:09
http://herbreview.org/how-to-lower-blood-pressure-naturally-with-nattokinase-and-exercise/ Nattokinase, at a dose of 4000FUs, lowers BP quickly - especially if taken shortly before exercise. Aerobic exercise works best. Walking is a good example. In this video I demonstrate the BP lowering effects of nattokinase with jogging and sprinting, but I think walking for 45 minutes will have the desired effect. So what is nattokinase? It's an enzyme that is extracted from traditional Japanese soy food natto. The enzyme was discovered only recently by Dr Hiroyuki Sumi in 1980 at the University of Chicago. So what is nattokinase so important? The body produces several enzymes that promote clot formation, but only one, plasmin, to dissolve them. Furthermore, levels of plasmin reduces with aging. The effect of nattokinase resembles that of plasmin. And it's a fairly inexpensive supplement when compared to blood thinning drugs. Furthermore, it works even better than pharmaceutical drugs. Nattokinase does not inhibit body's reaction to form new clots around a trauma, but pharmaceutical drugs will inhibit critical coagulation. Nattokinase is a natural agent that thins and dissolves blood clots effectively, with relative safety, without side effects. It's the Aspirin strategy without the pitfalls. The traditional Japanese food Natto has been used safely for over 1000 years. The potent fibrinolytic enzyme nattokinase appears to be safe based upon the long-term traditional use of this food. Nattokinase can be used preventatively. It is a naturally occurring, food based dietary supplement that has demonstrated stability in the gastrointestinal tract, as well as to changes in pH and temperature. Furthermore, regular use of nattokinase may help prevent your cognitive abilities as you age. Blood clots cause strokes and SENILITY. Nattokinase can keep blood clots from forming or dissolve existing clots. And it's more effective than blood-thinning drugs. Your blood needs to be just right - not too thick, not too thin. The body makes enzymes that cause clotting so it doesn't keep bleeding after surgery or injury. But the body makes only one primary enzyme to thin blood - plasmin. Nattokinase works a lot like plasmin - but doesn't cause excessive bleeding like blood thinners, and doesn't have side effects. Thrombotic clogging of the cerebral blood vessels may be a cause of dementia. It has been estimated that sixty percent of senile dementia patients in Japan is caused by thrombus. Thrombotic diseases typically include cerebral hemorrhage, cerebral infarction, cardiac infarction and angina pectoris, and also include diseases caused by blood vessels with lowered flexibility, including senile dementia and diabetes (caused by pancreatic dysfunction). Nattokinase holds great promise to support such patients. Scientists at Yonsei University in Korea tested 86 individuals aged 20 to 80 whose blood pressure ranged from 130 to 159 mmHg. Each received either nattokinase at 2000 FU (fibrinolytic units) per capsule daily or a placebo. After eight weeks, those on nattokinase had significantly lower systolic and diastolic blood pressure. The researchers conclude, "These findings suggest that increased intake of nattokinase may play an important role in preventing and treating hypertension." Nattokinase is an enzyme extracted from natto. One of nature's most powerful blood thinners. It dissolves clots and prevents their formation in some cases. A Taiwanese study showed no adverse effect from two capsules of nattokinase (2000 FU per capsule) a day for two months. It may help reduce blood pressure as thins blood. It dissolves fibrin (tiny fibers) that make up the meshwork of the blood clot. Or it may act like plasmin - the natural enzyme in human blood that maintains the right viscosity. The higher the dosage, the stronger the blood thinning effect, so need to be mindful of that. A word of caution - combining nattokinase with warfarin, plavix, effient or other prescribed blood thinners; aspirin or any other herb or medicine that thins the blood or prevent blood clotting may have a dangerous additive effect and lead to excessive blood thinning. Take nattokinase on an empty stomach.

10 Health Benefits of Grapefruits
 
05:30
Important: Medications can interact with all forms of grapefruit - the fresh fruit, juice or even the frozen concentrate can result in problems. Interactions may occur with commonly used drugs - such as those that lower cholesterol, treat high blood pressure, or fight cancer. If you drink grapefruit juice, always have your pharmacist check for drug interactions with any new prescription or over-the-counter (OTC) drug. Oranges and lemons are the most commonly used citrus fruits. But did you know that grapefruits can be great for your health? Grapefruits can be good for your body in many ways. In fact, grapefruit is known as the “fruit from paradise” because it’s very helpful to your health, and can also stop sicknesses from coming. Grapefruits are full of vitamin C, a strong antioxidant. They also have vitamin A, potassium, folate, thiamin, vitamin B6, calcium, iron, copper, phosphorus, and magnesium, and some phytonutrients and flavonoids. Here are the top 10 ways grapefruit can be good for your health. 1. Aids Weight Loss Grapefruits are good for people trying to lose weight  because they are full of vitamin C, fiber, and water. The vitamin C will help your metabolic system work properly and also control the breaking down of fats, which will help the body burn fat. 2. Stabilizes Blood Sugar The American Diabetes Association advises people with diabetes to eat grapefruit. This is because grapefruit is a low- glycemic food, and does not cause blood sugar to rise right after it’s eaten. 3. Protects Against Cancer Grapefruit can help lower the risk of cancers of the stomach, colon, bladder, breast, and esophagus. 4. Reduces Risk of Kidney Stones Drinking grapefruit juice every day can help lessen the risk of calcium oxalate kidney stones. Because grapefruits have so much citric acid they can stop stones from forming, and even break up small stones that have already formed. Citric acid makes the urine unfit for stones to form. 5. Protects Heart Health Grapefruits are also good for our heart health, because they are full of vitamin C. They also have a lot of potassium, which works as a vasodilator, which means that it helps the blood vessels and arteries relax. This lowers blood pressure and lessens the risk of heart attacks and strokes. 6. Lowers Bad Cholesterol Grapefruits have a few flavonoids. The main flavonoid hesperidin in grapefruits raises ‘good’ high- density lipoprotein (HDL) cholesterol and lowers ‘bad’ low- density lipoprotein (LDL) cholesterol and triglycerides. A study done in 2006 showed that eating only one grapefruit a day can help lower your LDL cholesterol levels by 15.5 percent and triglycerides by 27 percent. 7. Boosts Immunity Grapefruits help raise immunity and lessen the  problem of getting infections and common colds. 8. Improves Skin Health The vitamin C in grapefruit is also good for healthy skin. Vitamin C is needed to make healthy collagen which helps keep your skin plump and smooth. Also, because of the grapefruit’s antioxidants, it fights the body’s cell aging that’s caused by harmful free radicals. 9. Fights Gum Disease Because grapefruits have so much vitamin C, they are very helpful for fighting gum disease. A healthy gum line is important for strong teeth. A study done in 2005 showed that eating grapefruit every day lessened gum bleeding in people with gum disease. 10. Cleanses the Liver Grapefruits can help clean out poisons from the liver because it has glutathione, a strong antioxidant that gets rid of free radicals. The phytonutrients in grapefruit, called limonoids, help take  toxins out of the liver by making them melt from water. Also, the flavonoid compound called naringenin helps the liver burn fat, instead of storing it. Make sure to always buy grapefruit that are firm and springy to the touch. For extra health, choose the pink and red grapefruits. Keep grapefruits stored at room temperature before juicing them to get the most out of them. To better the taste if you find that your grapefruit juice is too bitter or sour, add juice form green apples or carrots.

All rights reserved. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The cardiac conduction system consists of the following components: - The sinoatrial node, or SA node, located in the right atrium near the entrance of the superior vena cava. This is the natural pacemaker of the heart. It initiates all heartbeat and determines heart rate. Electrical impulses from the SA node spread throughout both atria and stimulate them to contract. - The atrioventricular node, or AV node, located on the other side of the right atrium, near the AV valve. The AV node serves as electrical gateway to the ventricles. It delays the passage of electrical impulses to the ventricles. This delay is to ensure that the atria have ejected all the blood into the ventricles before the ventricles contract. - The AV node receives signals from the SA node and passes them onto the atrioventricular bundle - AV bundle or bundle of His. - This bundle is then divided into right and left bundle branches which conduct the impulses toward the apex of the heart. The signals are then passed onto Purkinje (pur-KIN-jee) fibers, turning upward and spreading throughout the ventricular myocardium. Electrical activities of the heart can be recorded in the form of electrocardiogram, ECG or EKG. An ECG is a composite recording of all the action potentials produced by the nodes and the cells of the myocardium. Each wave or segment of the ECG corresponds to a certain event of the cardiac electrical cycle. When the atria are full of blood, the SA node fires, electrical signals spread throughout the atria and cause them to depolarize. This is represented by the P wave on the ECG. Atrial contraction , or atrial systole (SIS-toe-lee) starts about 100 mili-seconds after the P wave begins. The P-Q segment represents the time the signals travel from the SA node to the AV node. The QRS complex marks the firing of the AV node and represents ventricular depolarization: - Q wave corresponds to depolarization of the interventricular septum. - R wave is produced by depolarization of the main mass of the ventricles. - S wave represents the last phase of ventricular depolarization at the base of the heart. - Atrial repolarization also occurs during this time but the signal is obscured by the large QRS complex. The S-T segment reflects the plateau in the myocardial action potential. This is when the ventricles contract and pump blood. The T wave represents ventricular repolarization immediately before ventricular relaxation, or ventricular diastole (dy-ASS-toe-lee). The cycle repeats itself with every heartbeat.

HPLC chromatography
 
16:29
HPLC chromatography lecture - This lecture explains about the HPLC chromatography technique in a nutshell by Suman Bhattacharjee. HPLC is performed to separate organic and biological compounds using solid stationary phase. High Performance Liquid Chromatography (HPLC) is a form of column chromatography that pumps a sample mixture or analyte in a solvent which is known as the mobile phase at high pressure through a column with chromatographic packing material known as stationary phase. The sample is carried by a moving carrier gas stream of helium or nitrogen. HPLC has the ability to separate, and identify compounds that are present in any sample that can be dissolved in a liquid in trace concentrations as low as parts per trillion. Because of this versatility, HPLC is used in a variety of industrial and scientific applications, such as pharmaceutical, environmental, forensics, and chemicals. Sample retention time will vary depending on the interaction between the stationary phase, the molecules being analyzed, and the solvent, or solvents used. As the sample passes through the column it interacts between the two phases at different rate, primarily due to different polarities in the analytes. Analytes that have the least amount of interaction with the stationary phase or the most amount of interaction with the mobile phase will exit the column faster. This lecture explains the following things about Hplc chromatography - 1. Hplc chromatography principle 2. Hplc chromatography instrumentation 3. Hplc chromatography types High-Performance Liquid Chromatography - Other HPLC Types Ultra High Performance Liquid Chromatography (uHPLC): Where standard HPLC typically uses column particles with sizes from 3 to 5µm and pressures of around 400 bar, uHPLC use specially designed columns with particles down to 1.7µm in size, at pressures in excess of 1000 bar. The main advantage of an uHPLC is speed. These systems are faster, more sensitive, and rely on smaller volumes of organic solvents than standard HPLC, resulting in the ability to run more samples in less time.

Angioplasty Procedure Animation Video.
 
02:55
Angioplasty Procedure Animation Video Emergency angioplasty is an operation that is performed directly after a heart attack, on admission to the hospital. It involves the insertion of a catheter into the blocked blood vessel that caused the heart attack. This opens it up and allows blood to flow again, thus minimizing damage to the heart. If one or more arteries become clogged, it may result in a heart attack. This normally presents with chest pain, sweating and a feeling of anxiety, among other symptoms. Urgent medical assistance should be sought. A heart attack is a medical emergency requiring intervention as soon as possible. Know more: http://www.emergencyangioplasty.com/
