Skills Blood Pressure Measurement
Taking a patient's blood pressure is a necessary part of our patient care. The blood pressure provides us the ability to treat and trend our patients as long as it's taken accurately. Auscultation and palpation are two of the most common methods used. However, there are a number of factors we should keep in mind so that our readings are accurate. The arm must be placed at heart level. Cuff size is based on a limb size, so measure the cuff appropriately. Place the cuff over the brachial artery, keeping the.
Bottom of the cuff one to one half inches above the bend in the elbow. Insert the stethoscope in your ears with ear pieces pointing slightly forward. Gently tap on the diaphragm to assure the stethoscope is positioned correctly. Palpate the brachial artery and place the bell of the stethoscope over the brachial artery. Palpate or auscultate the brachial artery while inflating the cuff to 30 millimeters of mercury above the loss of the pulse. Deflate the cuff at a rate of two to three millimeters per mercury per second. Too fast or too slow of a deflation results in missing.
Sounds and inaccurate readings. The systolic pressure is recorded when you hear at least two consecutive sounds and the diastolic pressure is recorded when the sound becomes muffled. The arm must be placed at heart level. Cuff size is based on a limb size, so measure the cuff appropriately. Palpate the brachial artery and place the cuff over the brachial artery, keeping the bottom of the cuff one to one and a half inches above the bend in the elbow. Palpate the brachial or radial artery while inflating the cuff to 30 millimeters of mercury above.
Taking a Blood Pressure by Palpation
This is how you palpate a blood pressure. The reasons for palpating a blood pressure is primarily because you cannot hear or auscultate for a blood pressure. Sometimes in the back of a noisy ambulance this is impossible to do so this is one way we can at least get a portion of the blood pressure. The only thing this will represent though is the systolic. We will not get a diastolic during this procedure, first, locate the radial pulse. Making sure your patient is in a comfortable seated position. Expose the arm. Place this blood pressure.
Cuff again over the brachial artery. Feel for a pulse again. A radial pulse. As I pump itup I will continue to feel it. And at the point where it goes away ill add about 20 or 30 millimeters of mercury and then slowly allow the air to release. At the time the pulse returns, there, is my systolic. And I am done. This is only going to give me the top number or the systolic. And the way you will represent this on your documentation is to put whatever number the systolic is, we will say 120.
Dr. Laura Pak The Importance of Vascular Screenings Marin General Hospital
This is KROM4 Medical Minute we are here with Medical Director of Vascular Surgery here at Marin General Hospital Doctor Laura Pak. So Doctor we are talking about vascular screenings, very important. So why are they so important Vascular disease can be a silent killer. So then what are you screening for PAD Peripheral Arterial Disease, Aortic Aneurysms, Carotid Disease, Varicose Veins even What do you do with the screenings, how does that work We have a vascular ultrasonographer who will do an exam on you, minimally invasive and then afterwards you meet oneonone with a doctor, or physician assistant, to.
Auscultated Blood Pressure
This is how you auscultate for a blood pressure. First have your patient in a seated position, locate the brachial pulse. Expose the arm and put the blood pressure cuff with the arrow directly over the brachial artery. Take up as much slack as you can. You want to close off the valve by going to the right. Using your stethoscope start in the middle of the antecubital fossa rotate it towards the middle. Do not place your thumb on here just your finger. You will not hear anything at first. What you want to do is we want to start putting.
Air into the cuff until the point where you can hear the pulse, we will keep going until the pulse goes away then we'll add about 2030 mm of mercury beyond the point where we can hear. So as I inflate, I can hear, I can hear, it's gone away, I'm going to add about 2030 more. Slowly I'm going to allow the air to come out, at the point where I hear a pulse coming back is my systolic. At the point where is disappears is my diastolic. And the procedure.
Regulating Arterial Blood Pressure
One of the things that we know about hypertension is, first of all, it affects one out of every three adults. It's an epidemic in our country and it's one of the major concerns for institutes like NIH and the American Heart Association. It's primarily two disease models. Hypertension, which is higher blood pressure. And lower blood pressure, which is orthostatic intolerance. For someone who has really low blood pressure, they may have trouble standing up with this. So with the micronography technique we're taking a tungsten microelectrode and we're inserting it into the peroneal nerve.
And this right now is the gold standard for assessing sympathetic traffic. It's the only method out there where we can get direct signals of sympathetic traffic. When we're probing for a sympathetic nerve we're listening for what we call an insertion burst. That insertion burst will give us an indication that we're actually in the nerve. Now we still have to make tiny microadjustments sometimes in order to get there because we're actually recording from multiple fibers. And what we're interested in is, individuals who are more prone to fainting have lower.
Sympathetic tone, lower sympathetic traffic, and, or, they have a reduced ability to increase sympathetic traffic. So on one scale, one side of the spectrum we're looking at fainting and orthostatic intolerance. On the other side of the scale, someone who has a high sympathetic traffic, outflow, and tone, often is associated with hypertension. And so we look at these patients and try to characterize their activity levels, and then we expose them to various types of intervention. So one intervention is getting more sleep, other interventions are physical activity. One that we just completed was looking at the effects of the Omega3 fatty acids,.
