Yes, a very good explanation. I wanted to know how blood pressure measurement worked, it took me a few tries, but soon I reached this video. It told me what I wanted to know. Thank you Bio Geek.
Excellent presentation for visual learners like me! Your animation deserves a thumbs up! Summary of the principle: 1. wear your stethoscope 2. pump air into the blood pressure cuff so as to OBSTRUCT blood flow completely upon overinflation. The stethoscope does not give a pulsating sound now. 3. rotate the gas flow valve in front of the pump to let some gas out of the cuff till you hear the first sound that is produced by turbulence of blood flow in the artery. This first sound corresponds to SYSTOLIC BP. So, look at the measurement! 4. Continue letting out the gas till the sound disappears! Since blood flow is normalized, the artery gets its normal shape. The disappearance of the sound corresponds to the DIASTOLIC BP. So, now you have the two numbers of BP measurements!
Awesome summary... actually I am not able to get his accent eventhough he explained good enough... captions too not available.Tonnes of thanks to you for making this summary
Thank you for the explanation man, I have to do a video explaining about how sphygmomanometer work and this video explains a lot and make me understand it deeply. Thank you for making this video!
Excellent graphic, a very clear explanation as to the point at which we hear the systolic pressure and the diastolic pressure. Very impressive! Thank you!
Very good explanation! Thank you. I've been trying to use a pressure monitor, but had a lot of uncertainty about how it was supposed to work. This makes its operation very clear to me!
i really appreciate the thorough explanation - i am learning to take blood pressure manually for a course, but struggled to remember the steps. knowing what is actually happening really helps
Thank you, this video does help me understand blood pressure more. I was curious to see how the 'old school' so I can make a better call when using either the arm or wrist cuff blood pressure monitors. Arm is more consistent since it's easier to discern the points where the heart beat stops being audible and more consistent as there's more skin, tissue to isolate environmental factors. Whereas wrist is a bit more variable due to how little tissue there is, and how much more exposed and further away the radial valve is from the heart. It sounds like a pros/con situation where as I am seeing as long as people are aware of what they're looking for in their blood pressure readings, then it's okay to use either. And why I can see hospitals still use arm cuffs. If the variance between sys/dia is too high +/- 10, it can lead to an easy misdiagnosis for that visit/procedure and they're not going to sit there between every 5 minutes to measure again for an average. On the other hand, for at-home monitoring, where we're just wanting to get a general feel of our heart health, I am seeing that wrist cuffs aren't bad, so long as people can practice consistent measuring techniques (e.g. monitor is at similar height as heart, to allow for compensation of pressure drop between two points (explained by conservation of energy principles). We are looking for consistency, rather than accuracy. I'm hoping I'm understanding this right.
what an amazing video! I have my medical clinical practices coming up and I have to take BP measurements and even though i understood the process, I never properly understood the theory behind it. Cheers for explaining it so well
That was AWESOME! I totally learnt how this cuff works. Now that I know the mechanism I think I can measure bp manually correctly even in pediatrics, obese or old patients 💆🏻 Thank you ♡
This is awesome been doing it just 2 years and seeing this helps me understand getting vitals better. Thanks. I normally have a hard time hearing them just go to palpation.
Best explanation of how blood pressure measuring actually works! Thank you! Why is the blood pressure reading falsely elevated when the blood pressure cuff is too small? Thank you =)
OMG Thank you for the great explanation. I’ve always wondered about how BP monitors worked and what voodoo tricks they pulled and in a few mins, you explained it all. WOW!! Thank you so much!! 🙏🙏🙏
Really ,thank you dr ❤️🙏🏻 Now only i can say iam understanding what is the mechanism of blood pressure 😃👌 Iam medical student and i was not known how the sphygmomanometer work But you help me more to understand many things in CVS 🙏🏻❤️ and BP Really ,thank you 🌹
Is there anything physical that could cause a change in the blood pressure numbers like distance from the heart, size of blood vessels, number of blood blood vessels, body fat, muscle, or clothing under the cuff?
I am not a nurse,I,m using a digital cuff and would like to understand what is happening when the digital display goes very high say 160 then starts to drop as little heart icon comes on and starts flashing as the digital display drops before flashing the final reading say 134/83
The 160 would be the max Cuff pressure before it starts releasing air. Initially, it needs to exceed your systolic (your high number) to completely cut off blood flow to your lower arm. You will hear the pressure release bit by bit. When blood finally starts flowing through your artery towards your hand again it only goes in spurts (every time the heart beats). This is your systolic which the digital Cuff records. Air will continue to be released. When blood flows through your artery uninterrupted that's you low number (diastolic) which is when your heart relaxes between beats. The flashing heart you see is your pulse.
I was wondering that, too. Maybe the sound is from the built-up blood going back to "regular" pressure. I think the plot was showing that there was less build-up as the cuff pressure decreased. Less pressure would likely cause less sound, even though the remaining sound we do hear lasts longer. When the pressure decreases enough, we don't detect the sound at all, but maybe the people with excellent hearing hear an almost constant sound. Just my speculations, as I don't work in this field.
It's because the artery stays open. You only hear the sound when there is turbulence from the artery opening and closing (which is the case when the cuff pressure is between diastolic and systolic.
What you are listening for is "Turbulence" caused by the restriction of the artery. Once the cuff is lower than diastolic there is no restriction to cause the turbulence so the sound goes away.
It turns out I have white coat syndrome. At the doctor office my blood pressure shoots up to 160 and my pulse goes up to 100 so my doctor thought that i was dying 🤣 and told me to take my blood pressure at home and keep a log. My blood pressure at home aversges 119/66 with a pluse of around 60 so I believe I'm good thank God.
Same here man. Last time mine were 178/120 with HR: 140. But I was having a panic attack cause I get so nervous when they take my vitals. Went home and they were normal.
Best explanation! Should be result number 1 to "How does blood pressure measurement work?"
Thank you, sir!

The best technical explanation for BP. Thanks for your effort Nova Scotia.
To the point, thanks! Should be #1 for "how blood pressure machine works".

Literally the oscar level explanation!!
Excellent explanation sir...
so helpful thanks a lot
greate greate explenenation thank u very much dear
Amazing explanation! Thank you!
Thank you for your explanation !!!
Great explanation. Thank you.
I always wanted to know the black magic behind that thing wrap around the arm.
Is there anything physical that could cause a change in the blood pressure numbers like distance from the heart, size of blood vessels, number of blood blood vessels, body fat, muscle, or clothing under the cuff?
Do the automatic machines work similarly? Meaning, if it tightens to 150, will systolic always be under 150? How does it know how tight to go?
I think they work the same way. There must be some sort of of sensor on the cuff to detect the pulse as it comes and goes with systolic and diastolic.
I am not a nurse,I,m using a digital cuff and would like to understand what is happening when the digital display goes very high say 160 then starts to drop as little heart icon comes on and starts flashing as the digital display drops before flashing the final reading say 134/83
The 160 would be the max Cuff pressure before it starts releasing air. Initially, it needs to exceed your systolic (your high number) to completely cut off blood flow to your lower arm. You will hear the pressure release bit by bit. When blood finally starts flowing through your artery towards your hand again it only goes in spurts (every time the heart beats). This is your systolic which the digital Cuff records. Air will continue to be released. When blood flows through your artery uninterrupted that's you low number (diastolic) which is when your heart relaxes between beats.
The flashing heart you see is your pulse.
@@thebiogeek8435 Same question and thanks for your clear reply.
Great video!!!!!!!
so if you are stronger you have an inherent low blood pressure reading since the muscle mass makes it harder to squeeze the cuff?
Best explanation,that also using animation
Thanks man!
really excellent
Excellent. Thank you.
This presentation should be the first part of taking bp lessons
Really informative! Thank you
Why does the sound disappear once the pressure on the dial reaches diastolic pressure?
I was wondering that, too. Maybe the sound is from the built-up blood going back to "regular" pressure. I think the plot was showing that there was less build-up as the cuff pressure decreased. Less pressure would likely cause less sound, even though the remaining sound we do hear lasts longer. When the pressure decreases enough, we don't detect the sound at all, but maybe the people with excellent hearing hear an almost constant sound.

confusing as hell.
HAVEN'T SEEN A MANUAL TESTER IN OVER 20 YEARS..! SHOULD HAVE INCLUDED REAL WORLD, ELECTRONIC TESTER...😡😡😡😡👎👎
Great explanation! Thank you!
Thanks
