Normal blood pressure is important for proper blood flow to the body’s organs and tissues. The force of the blood on the walls of the arteries is called blood pressure. Blood pressure is measured both as the heart contracts, which is called systole, and as it relaxes, which is called diastole. Normal blood pressure is considered to be a systolic blood pressure of 115 millimeters of mercury a diastolic pressure of 70 millimeters of mercury (stated as "115 over 70"). If an individual were to have a consistent blood pressure reading of 140 over 90, he would be evaluated for having high blood pressure. If left untreated, high blood pressure can damage important organs, such as the brain and kidneys, as well as lead to a stroke. High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. Measuring Blood Pressure Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high. Health care workers check blood pressure readings the same way for children, teens, and adults. They use a gauge, stethoscope or electronic sensor, and a blood pressure cuff. With this equipment, they measure: Systolic Pressure: blood pressure when the heart beats while pumping blood Diastolic Pressure: blood pressure when the heart is at rest between beats Health care workers write blood pressure numbers with the systolic number above the diastolic number. For example: 118/76 mmHg People read "118 over 76" millimeters of mercury. Normal Blood Pressure: Normal blood pressure for adults is defined as a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg. It is normal for blood pressures to change when you sleep, wake up, or are excited or nervous. When you are active, it is normal for your blood pressure to increase. However, once the activity stops, your blood pressure returns to your normal baseline range. Blood pressure normally rises with age and body size. Newborn babies often have very low blood pressure numbers that are considered normal for babies, while older teens have numbers similar to adults. Abnormal Blood Pressure Abnormal increases in blood pressure are defined as having blood pressures higher than 120/80 mmHg. The following table outlines and defines high blood pressure severity levels. The ranges in the table are blood pressure guides for adults who do not have any short-term serious illnesses. People with diabetes or chronic kidney disease should keep their blood pressure below 130/80 mmHg. Although blood pressure increases seen in prehypertension are less than those used to diagnose high blood pressure, prehypertension can progress to high blood pressure and should be taken seriously. Over time, consistently high blood pressure weakens and damages your blood vessels, which can lead to complications. Types of High Blood Pressure There are two main types of high blood pressure: primary and secondary high blood pressure. Primary High Blood Pressure Primary, or essential, high blood pressure is the most common type of high blood pressure. This type of high blood pressure tends to develop over years as a person ages. Secondary High Blood Pressure Secondary high blood pressure is caused by another medical condition or use of certain medicines. This type usually resolves after the cause is treated or removed. Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, "blood pressure" usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg. Blood pressure varies depending on situation, activity, and disease states. It is regulated by the nervous and endocrine systems. Blood pressure that is low due to a disease state is called hypotension, and pressure that is consistently high is hypertension. Both have many causes which can range from mild to severe. Both may be of sudden onset or of long duration. Long term hypertension is a risk factor for many diseases, including kidney failure, heart disease, and stroke. Long term hypertension is more common than long term hypotension in Western countries. Long term hypertension often goes undetected because of infrequent monitoring and the absence of symptoms. Physiology: During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. Q. What blood pressure should I have? What is normal blood pressure?

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.

Mean arterial pressure (MAP) calculation formula explained for nursing students and nurses. What is a mean arterial pressure (MAP)? Mean arterial pressure is the pressure in your arteries during one cardiac cycle, and it tells us how well the vital organs (like the renal system, brain etc.) are being perfused. In addition with the brain, the MAP is very important when calculating the cerebral perfusion pressure. The MAP should be greater than 65 mmHg.

Greetings my fellow Nurses, today Im going to discuss Arterial lines with their Pressure Transducer and reasons for Art Line use in critical care. So arterial catheter connected to a pressure transducer are used for real time blood pressure (systolic, diastolic, mean and pulse pressure. The reason patients need this are for specific conditions like * Labile blood pressure * Anticipation of haemodynamic instability * Titration of vasoactive drugs * Frequent blood sampling * Morbid obesity (unable to fit an appropriately sized NIBP cuff) Don't forget that the Arterial line other than blood pressure can be used for * pulse rate and rhythm * effects of dysrhythmia on perfusion * ECG lead disconnection * continuous cardiac output using pulse contour analysis * specific wave form morphologies might be diagnostic * tamponade & also for pulse pressure variation (suggests fluid responsiveness) COMPLICATIONS to assess my fellow nurse brothers and sisters are the 5 P’s -Pulselessness -Pallor -Pain -Paresthesia -Paralysis ----------------------------------------------------------------------------------------------- Don't Forget to Follow NurseMendoza & P.L.A.N ✌🏽️Peace ❤️Love 🗣Advocate 😷NURSEpiration ------- Thank you for watching this video my fellow nurses, student nurses and aspiring nurses.

Finally, the ABG explained in an easy to understand way! If you want to learn this lab test once and for all, check out this awesome video! 01:22 Introduction to the basics. 07:57 ABG Components and normal values 13:21 Interpretation of the numbers 14:51 Examples of acid-base disorders 18:44 Knowledge challenge questions! Good luck in school!! In this video about the arterial blood gas lab, the ABG, I'm gonna start with an introduction to the basic concepts about an ABG, and then, I will talk about the components individually and their normal values, followed by how to interpret the numbers or the interpretation of the ABG. Then, I'll give you some examples and we'll finish off with some knowledge challenge questions. All right, let's do it! So, the first thing I want to point out, guys, is that an ABG is an Arterial Blood Gas test. So, why is that important? Basically because most of the time in the clinic or the urgent care or ER, your access point to the patient is an IV, an intravenous line, not an arterial line. So, while you could pull blood from that IV and send it to the lab, the results that you got back would be a VBG, not an ABG, okay? And it's for that reason that most often times, the ABG is used in critical care settings, like an ICU or somewhere like that where a team has come in and gotten arterial access, which is more difficult than venous access. In less critical settings, like the clinic, the pulse oximetry is used more frequently, just because it's less invasive by far, it's faster, and definitely cheaper. An ABG is important because it gives us an idea about what's dissolved in the blood and also, for acid-base homeostasis. This is important because our bodies are extremely sensitive to swings in the pH. One of the most important things that could happen is denaturing of proteins. Now, that doesn't mean that they're gonna completely unfold. It just means that they're not going to function like they should and you're just gonna feel miserable. It's for this reason that our pH in our bodies is highly, highly regulated and that's done by two main systems, the respiratory system and the renal system, which I cover in this lecture. If you want to learn a little bit more about buffering agents, check out one of the links in the YouTube cards. The first thing that I want to talk about is the respiratory system and I think it's pretty easy to understand why the respiratory system has a big effect on the amounts of gasses dissolved in my blood and the reason is because hey, I mean, these are my lungs. They deal with gases all day long, right? But what about the pH? Why do the lungs have an effect on the pH? And the answer to that is found in carbon dioxide. You see, carbon dioxide, when dissolved in the blood, is able to transform or shift to carbonic acid, which is the same thing that you see in a fizzy soda pop. It's the fizz, it's the dissolved carbon dioxide, which turns into acid and then can re-express from the liquid in a gas form. So, if I decrease the amount of carbon dioxide in my blood, then I decrease the amount of carbonic acid and you can taste that in a soda pop. If a soda pop has been sitting out for a long time and has lost all its fizz, it tastes really too sweet and the reason is, is because it's not counterbalanced by that acidic taste, which kind of neutralizes the sweetness. So, if I were to hyperventilate, (huffing in and out) for a minute or two, I would ventilate off or degas my blood of carbon dioxide and therefore, decrease the amount of carbonic acid and then therefore, increase the pH or make my blood more alkalotic. The converse is also true. If I stop breathing for a period of time, I can increase the acidity or decrease the pH of my blood and this is a pretty fast response. If I were to hyperventilate for a few minutes, you would be able to notice a difference in the pH of my blood. It happens pretty quickly. Now, all of this applies to an ABG with the term, respiratory compensation and what that means is, let's say that I have a disease process in my body that's causing my blood to be too acidic. Well, normal physiology, the respiratory compensation would be for me to breathe faster. This happens automatically. It's normal physiology. I would breathe faster to degas or ventilate off carbon dioxide and that would decrease the amount of carbonic acid and bring my pH closer to normal, okay? And again, that's a fast process. This is normal physiology and it's called respiratory compensation and we'll talk a little bit more about it later on, okay? Let's move on. The second system that I want to talk about that's important for the ABG is the renal system. The renal system can change the amount of dissolved substances in the blood by how much the nephrons retain or secrete those molecules of interest and in this case, for pH, we're interested in bicarbonate and hydrogen ions.

We apologize for any inconvenience this may cause. Transducers in Invasive Pressure Monitoring, 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. Today I'm going to be talking about invasive monitoring, specifically arterial pressure monitoring and central venous pressure monitoring. We're going to spend a little bit of time talking about transducers and how they work. Transducers. Transducers are a system that converts a mechanical signal, which in this case-- in the case of pressure monitoring-- both for arterial lines and central venous pressure lines, is a pulsatile signal, and it's converted through the transducer, and then through this cable converted to a digital signal pressure waveform, which is what you see on the monitor. And we're not going to spend a lot of time talking about electronically how that works, but suffice it to say that in order for a transducer to work, it has to be connected by a continuous column of fluid to the fluid in the patient's body in the system that your monitoring, ideally with no bubbles in it. Because as we'll talk about the presence of bubbles in the transducer system degrades the conversion of the pressure signal to the electronic signal that we see on the monitor by damping out the pulses in the system. So, we have this continuous volume of fluid and we have the transducer generally hooked to a flush system. In this case, this is normal saline with a little bit of Heparin added running in about three mLs an hour, which is pretty typical, And that may vary from institution to institution. And that's just the volume of fluid necessary to keep the system free of clot and to prevent any thrombus forming on the ends of the catheters, which will also degrade the quality of the system and obviously creates a potential risk to the patient.
