Understanding Pulse Pressure

[@ayeleru7489]

There's a way something elusive finally gets explained that gives you the confidence that you'll probably NEVER forget again. This is one of those. THANK YOU. Wish I could like this video 10 times

[@kodochafan13]

thank you for this thorough explanation!! What's great about it is that I can apply this understanding instead of memorizing it, as you said in the video. amazing!

[@thewanderingeberlins4173]

Thank you! Studying for CRNA school and this makes everything makes sense. I hate memorizing! You forget everything immediately after the test. But if you understand the WHY you’ll always remember!

This is a fantastic video. I want to add to this. The narrow pulse pressure in cardiogenic shock and hemorrhage is probably due to vasoconstriction (compensatory response). When the blood vessel (smaller) is narrowed, the volume of blood vessels is decreased, which will increase pressure in the blood vessel (diastolic pressure) according to Boyel's law (it applies to fluids as well). The Opposite is valid for septic shock where blood vessels are dilated.

OMG OMG OMG thank you. I have had so many mediocre, monotone professors explain this and it never stuck.

[@Angela-cb8bt]

OMG! THANK YOU SO MUCH FOR MAKING THIS VIDEO!!!! THIS HELPED ME SO MUCH!!! I'VE BEEN WAITING FOR SO LONG TO FIND A VIDEO THAT EXPLAINS THIS IN A WAY I CAN UNDERSTAND!!!😂😂😂

fantastic teacher. every med student's dream

[@amzadhossain9991]

I watched it with autogenerated subtitle and got it. Thanks man. ❤️

[@vasug39]

You are a great teacher man!! Thanks for the explanation. You made the confusing concept pretty easy.

[@christianhowe8961]

this was a phenomenal explanation

[@hellfree1]

I noticed my pulse pressure is narrower during menstruation. Thank you for your explanation.

[@Adelicows]

You should only be losing about 1.5 teaspoons of blood per day menstruating. If you're losing as much blood as a trauma patient then something's wrong.

[@ahmedistiak]

A great explanation on this topic. Thank you, doctor!

[@johnolive9477]

Thanks a lot! Looking forward to more of your pharmacology videos!

[@rida3209]

Very nicely explained 😊

Thank you for explaining this so well. I have mentioned my episode with a narrow pulse pressure to some medical staff and no one seems to be concerned. Of course, most were nurses that didn't really know what I was referring to. My standing blood pressure the other day was 98/83. I have been having some issues off/on for years with chest pain and PVC, but I am having a recent "episode" with pulse pressure/blood pressure. When I feed my chickens and rabbits (nothing strenuous) I have chest pain and pins and needles in my head. I had the most severe headache of my life come over me out of now where (we are talking minutes). It relieved from a 10 to a 5, but I still went to ER. I haven't been able to completely relieve the headache since (5 days). The day after the ER is when I noticed the narrow pulse pressure, I had it once (about a week) before in Jan. I took my blood pressure standing, sitting, lying, both arms, other people, etc. to test my BP machine. While in the ER my BP was 156/103, yesterday at primary 148/99, both times I was in extreme pain with my head and I get extremely nervous and tense going to dr. The day before the primary visit, my BP upon waking, no food, standing was 126/111, sitting later that day 109/84, standing 119/94. It started out at PP 15 and 25 and slowly made its way into the 35 toward nightfall. It was better today, but I have been mostly on bedrest since the ER trip. I am starting to feel better and move around. My BP usually runs low normal. I would have never thought to check my BP but I felt so sick. The test at ER all checked out labs, CT of head and neck (no aneurysm), and EKG. No one seems to be concerned except me. I am concerned that I am feeling better with rest but will go outside and exert myself causing damage. As I write this I still have a faint headache and tingling feeling in my head. Is there ever a time when a narrow pulse pressure is a fluke? Is it normal being that my BP is low normal? These are a few actual recordings of my BP over the last few days [105/67(PP38), 98/83 {standing}(PP15),134/108 (PP26), 111/82(PP29),104/83(PP21), 121/89(PP32)] so random! It's not the cuff I've monitored my spouse. Am I calculating the PP right systolic-diastolic? Is there a time when Pulse pressure is maybe not important, like in this instant when everything is so random and inconsistent, being that labs for the most part came back normal? Does pulse pressure go down upon standing? I appreciate this lesson. I am trying to educate myself so I can be a better advocate...or at least find out that I am a hypochondriac and stop worrying. A great way of explaining with the hose. Thanks once again!

[@chihuahuapixieprincess2482]

Look into Orthostatic Intolerance Hypotension. I can have pulse pressure of 13 in the morning, I have to sit down constantly.

[@Total_Body_Fitness_USA]

Two other things that come to mind that effects pulse pressure. A hole in the heart and lung disease such as COPD, etc.. Great video...

[@md.abalna2915]

thank you.. for explaining very clearly..

[@gargantuan6241]

Can weightlifting help fix a low narrow pulse pressure?

[@catrinmorrisdc]

I could never quite get why an older patient would have high pulse pressure. I mean, I memorized the facts and calculations but WHY. And then you explained why at minute 7:30 or so. It isn't so much that the diastolic is LOW in the elderly. it is that their noncompliant vessels make every systolic pulsation very intense relative to their standing hydrostatic pressure. Yay, My $78k accelerate BSN at Emory somehow never explained this seemingly straightforward fact.

[@elfredawright]

You could have learned that with a $300 CCRN examination vs $78K accelerated BSN🙃

[@Paxsina]

Great explanation! Thank you for this video

I have inappropriate sinus tachycardia. I sometimes have a Pulse pressure between 10 and 16 other times it’s closer to 30 or 40. I have been evaluated by several cardiologists some who have kept me in the office until my pulse pressure increased. My examinations, echocardiogram, and so on has been Unremarkable. So far I have been told that my heart is in good shape and there’s no sign of heart failure. What would be a reason why I would be experiencing a narrow pulse pressure? I feel it’s nearly impossible to get answers in this and I’m just looking for any suggestions or information that might help me understand why this is happening. I am in good physical condition don’t have any health problems other than inappropriate sinus tachycardia and I take no medication‘s.

[@suzzanechieh5292]

It's a good video and easy to understand. What about complete heart block? Does it cause increase in systolic pressure therefore causes the widened pulse pressure?

[@pewpewimsaad]

Thank you. This was very helpful.

[@baharehmirarmandehi658]

Amazing , finally I got the concept

[@warunakumara7671]

sir can you talk about the dengue fever and importancy pulse pressure , thank you for the video

[@stem5118]

I'm not sure if you answer questions but I am a little confused about aortic stenosis. I understand that a stenotic valve will not let as much blood out into the system creating a lower SBP; however, won't there then be a change in DBP because there is less blood to create the hydrostatic pressure?

[@atifbhore7740]

Actually, there should be reduced Diastolic Blood pressure since it is the pressure exerted on walls of artery during diastole. If stroke volume has reduced, then there is less blood volume to exert that much of a DBP, so DBP should reduce too. But since Systolic BP reduces alot more than DBP we get a Narrow Pulse Pressure.

This was a great explanation! Thank you!

[@ilincapuscas1392]

Thank you so much ! It helped me a lot!

[@mvuseledzomugodo1318]

This is brilliant

Amazing❤🎉

[@roland.j.ruttledge]

Very informative, many thanks UK

[@jameslin5678]

well expained. Thank you.

[@moulibiswas3348]

Very good explanation

[@ladanmahgoub4769]

But wouldn’t systolic pressure in ar also be low??

[@delnicholson9101]

This was fantastic. I too finally get it :-)

[@raffyaque8006]

Youre a god damn hero!!!

[@limitbreakerrob311]

sometimes i hit 40 sometimes 35... what does that mean. blood work came out good. just been stressed like crazy cause of little sleep and bow is acting up.
