How to Take Blood Pressure : Inflating a Blood Pressure Cuff

Now we want to inflate the cuff. An important
part of this is making sure that the dial on the blood pressure cuff is tightened all
the way up, so that when we pump the air through this, it’s going up into the cuff, and not
out the side.
We want to increase until we no longer hear a pulse coming through the brachial artery,
and then we’re going to go thirty millimeters of mercury above that, and that’s where we’re going to stop. That’s how you inflate the cuff.

    ummm….after you stop, how do u read the gauge and how do you record the number. He's checking the diastolic bp or systolic bp?….

    This video doesn't help that much..

  • jsj297

    it would help if he placed the scope over the brachial artery though. Just saying.

    I agree, I was thinking why not just do the palpable systolic first.

    as the title says, this video only explains the process of inflating the cuff. the video explanation of actually finding the systolic and diastolic pressures is different. and if you look on the right side of your screen you will see under "more from expertvillage" a lot of other videos about assessing blood pressure, including the one where he teaches you how to find systolic and diastolic bp.

    you release it slowly and listen or watch the gauge. It will go down steady and you will no longer here it and see the change and thats your dyst bp

    I wish these places would just use the electronic versions. I understand they're more accurate, anyway.

    I have been measuring my blood pressure without using a stethoscope. I release the air as slow as possible and, while carefully observing the gauge needle descending, the systolic reading is taken when the needle slightly starts oscillating. When the needle stops oscillating I take the diastolic reading.
    For this method to work it is necessary to tighten the unpressurized cuff as much as possible to the arm before inflating it, otherwise the needle motion will not be noticeably.

    That was worthless, coming from an EMT student. That teaches absolutely nothing pertinent.

    I too am studying EMS, this is just the first installment of a tutorial series. Why they split it up into several videos, I have no idea. But if you watch them in sequence it all makes sense.

    you dont say how to read the gauge, this is what i wanted to know about

    Thank you.  You are the first one to explain the brachial artery sound stopping when the cuff is inflated enough and then going 30mmHg past that before deflating where I actually understand it.  I will have to try that since I use a manual blood pressure gauge the next time I take my BP.  Great video.

    I don't know why I ever gave this video a thumbs up.  Maybe I still didn't understand how to take blood pressure.  I have researched this a lot and now it's a thumbs down for me.   First off you can't use the method he is using to find the cut off point because it is hard to completely close the artery with fat arms like mine or if the artery marker is in the wrong place.  So the best course of action is to inflate my  cuff until it begins to hurt(200mmhg) before I start deflating and reading the dial. 

    Secondly this doctor don't even know where the brachial artery is because he sure don't have the artery marker on the brachial artery on the inside of the arm, but on the top.   In fact many sphygmomanometer instructions shows exactly where the artery marker goes.     But after what I've seen in doctor's offices it's no wonder that patients complain of White Coat Hypertension and the reason I started taking my blood pressure at home more than 10 years ago.
