What are the adjectives errors contained by blood pressure taking?
Answers:
If done manually with a stethoscope and a cuff:
Putting your fingers on the bell of the stethoscope can throw it off.
Once you start pumping don't stop up to that time you reach the number you want it to get to, say 200, don't stop at 140 and afterwards start pumping more.
Listen to every beat. Dont let your mind play tricks on you.
Relying on the machines. As a cancer patient, I am in the hospital a lot. No one take manual bp's anymore, they are all done with those lil machines that also hold a pulsox and thermometer.
Anyways, a couple weeks ago, the machine was saying my bp be crazy high. It wasnt that high and I knew it. I know my body and how it feel if it were really that high. No one wanted to listen, and only just kept coming back with diff machines. Finally, I was approaching 'Does nobody here know how to do a manual bp?'
So they finally decided to do a manual. The cuff and pump within the room didnt work, so they had to go track one down. The first nurse that took it couldnt find it all. The second one get it after 3 times, and it was normal, not the crazy high that the gadget was showing. It was odd that 2 diff machines showed crazy lofty numbers, and they were of the mind that 2 machines said about the same point. But I know my body.
They had a couple others verify the normal reading manually.
But I was newly sitting there going..... I cant believe no one knows how to do this.
The machines will endow with inaccurate readings if the batteries are low. It is other best to plug them in when you are taking a bp, even if its fully charged.
Equipment related issues: (1) Chosing the wrong size of cuff for a patient -- children need BP cuffs that are proportional for their size; obese patients inevitability larger cuffs in order to get accurate reading. (2) applying the cuff to loosely or too tightly. You should be able to fit two fingers snugly under the cuff once it is applied.
Technique Issues: (1) Pressing the stethescope too tightly in the artery will inflict it to slightly compress and couuld obscure the onset and ending of the sounds. You can experiment beside a stethescope and produce the BP sounds by pressing the stethescope over the artery. (2) Deflating the cuff too slowly or too quickly. The former will cause blood to back up and will cryptic the diastolic reading. The latter could cause inaccuracy as the dial zooms down and you are unable to accurately assign a number to the sound's inauguration and end.
A lot of people measure BPs incorrectly. It does pocket some practice and hopefully some supervision by someone who is expert.
