Why Most People Get Blood Pressure Readings Wrong

hello you can see I'm wearing a blood pressure monitor that's because somebody recently commented out I've made a slight error with regard to one of the videos with regard to blood pressure it's very important where we position the arm with regard to blood pressure taking and we're going to try and highlight that now if the arm is hanging down and the patient just sitting upright unsupported you're going to get a falsely elevated blood pressure and conversely we should have the arm raised to the level of the heart and the patient relaxed that will give us our true blood pressure but to push that concept even further if you elevate the arm up then you're going to get a falsely low blood pressure so let's see those in action now so this blood pressure because my arm is down is going to be slightly elevated okay so that's giving me a blood pressure of 129 over 91 now we're going to make that blood pressure number come down by having me relaxed support backwards and raising the arm up and to really double down on that you shouldn't speak when you're having the blood pressure done because that can falsely raise the blood pressure because of how you're breathing in and out and affecting the air in the diaphragm I'm doing that now to demonstrate how significant the positioning of the arm is with regard to blood pressure because I know that the blood pressure is going to be lower even though I'm talking even though I'm doing the wrong things here blood pressure is coming down okay and there we go so we've got a blood pressure of 102 over 58 just from the positioning of the arm so there you have it done on camera the position of the arm matters to where you're doing the blood pressure try to have your arm elevated to the level of the heart and the patient relaxed lying back that's going to give you your true blood pressure reading hopefully that clears things up
