How do you check blood pressure by only using thier pulse's?

Answer 1

In trauma we use "pulse pressure" for very rapid assessments:

(a) Find the patients pedal pulse – if present, patient has a systolic blood pressure of at least 90 mm Hg

(b) If the patient has no pedal pulse, attempt to find the radial pulse – if present, patient has a systolic blood pressure of at least 80 mm Hg

(c) If the patient has no radial pulse, attempt to find the femoral pulse – if present, patient has a systolic blood pressure of at least 70 mm HG

(d) If the patient has no femoral pulse, attempt to find the carotid pulse – if present, the patient has a systolic blood pressure of at least 60 mm Hg.


Since a "healthy" person will always have all of these pulses, the approach doesn't do you much good in estimating a routine blood pressure.

Answer 2

When using pulses only to determine a patients blood pressure one can only determine an estimate reading. The body provides blood to the most neccessary areas of the body. therefore when the body is not undergoing any sickness or trauma, blood is being pumped to every part of the body but in an instance such as a major accident and the patient is losing blood the body will shut off the supply to the arms and legs and only provide enough to support the vital organs therefore not needing such a high blood pressure and put less workload on an already struglling heart.

For this reason the following estimates are:-
radial pulse 80-90mmHg
femoral pulse 70-80mmHg
carotid pulse 60-70mmHg

Answer 3

When you check someone's blood pressure manually you check the pulse. You only inflate the cuff after you find their pulse and with the scope on their inner elbow. Then when you inflate the cuff to about 180-200 and deflate very slowly wait until you can hear a clicking in the scope (in your ears) Make a note of the first number that you hear the click on and that is your top number. Then when you hear the last click (in your ears) you m ake a note of that number and that is the lower number. The numbers are always even and not odd. So you should do it by even numbers. If you tell some doctor that it was 127/91 he will think you are ignorant. Even it to the nearest even number.

Answer 4

Before the sphymomanometer was invented in the late 1800s, a doctor used the four index fingers to compress and stop the radial pulse. By slowly and evenly releasing the finger pressure he could feel the pulse move under one or more of his fingers.

How quickly the flow and pulse returned beneath the first and all fingers, and how it felt to his finger tips, allowed him to estimate if the pressure was low or high, but what it was precisely had to wait until more accurate instruments were developed. The more experience the doctor had affected how useful this manual technique was.

In medical school several of us tried this and compared what we guessed with what the results were with the sphygmomanometer. Of course, we had known reference pressures to test before getting an unknown to guess. It was hardest to guess slight variations in pressure but if someone really had low or high blood pressure we were surprised that we guessed correctly most of the time.

The sphymomanometer, and present day machines that function like sphymomanometers, has a pressure cuff that raises the pressure on your arm until the blood in your brachial artery stops flowing. The air pressure in the cuff can be seen in a mechanical manometer dial, or is measured by a digital transducer in the automatic bp machine, as it goes down the doctor listens to hear the first sounds of blood coursing past where the cuff squeezed the artery closed (these sounds are called Korotkoff sounds). These sounds initially get louder but gradually fade to inaudible as more pressure is released. The pressure reading at the first sounds is the Systolic pressure and the pressure at the point where the sound stops is the diastolic pressure.

Answer 5

You can only check the systolic blood pressure but will need the BP cuff for that.
You feel for the brachial pulse, which is found in the cubital fossa (other side of the elbow). Once you feel the pulse, you start inflating the BP cuff until you can't feel the pulse anymore. Slowly start releasing the air out of the cuff. The point where the pulse returns is your systolic BP or the upper limit.
But for an accurate measurement, you need the stethoscope to get both the systolic and diastolic (lower limit) BP.
For hypertenstion both upper and lower limits are important.

Answer 6

when you are taking a blood pressure you have a top number and a bottom number the top is systole its when your heart is actually contracting this number gives you the pressure at time of the heart is working and pushing blood into the arterys the bottom number is dyastole it is when the heart is at rest and refilling the ventricles of the heart with blood the biggest concern with taking a blood pressure is if your top and bottom is high and close togehther or they are both so low that you only here it one time the other way to take a blood pressure is to inflate your bp cuff and place your fingers on the artery in the bend of your arm and deflate your cuff until you feel a pulse that will give you the top number only

Answer 7

You can't. Some experienced practitioners may make an estimate by feeling a pulse, but it's not very accurate. The only way is by using the cuff.

Answer 8

You can't,your pulse just tells you how many beats your heart is beating,your bp is different,you need a device to check your bp.Nurse for 8yrs.

Answer 9

Try to feel the pulse on any of the 5 pressure points( side of neck, side of chest near armpit, upper arm near armpit, wrist, then side of upper thighs near private part) and count the beats in a minute basis. 70-90 beats is consider as a normal heart beat per minute.
Hope i helped you with that. Thats what i remember from my biology class... Ei, can you help me, check out these places. are they worth a visit? im gathering comments b4 i decide. thanks and hope you give a little time on this too...

Answer 10

you need a blood pressure cuff.
