Systemic Vascular Resistance (Total Peripheral Resistance) | Cardiology 

Dr. Mike, Dr. Matt, I love your teaching and so deeply grateful for your sharing your insights!

this is the first time I actually understood this concept. thank you so much

The presentation is really great and very informative, but for some reason I can't focus . I keep looking at how fit he is lol. bdw, thank you for creating this video

Let me tell you !!! This made a bunch of PowerPoint make sense to me because no what I read I couldn’t understand & FINALLY this help me I finally understand !!!! Dope video !!!

U r not just handsome but super smart and intelligent...... Carry on with the awesome work!!!😊😊😊❤️❤️

Great video. If your a plumber and know the basics that’s a start.

The best explanation until now.Thank you very much and please keep going!

This video is a God send! thanks Dr. Mike!

this explanation is amazing! i love the link to diabetes. just love love love this video! thank you!

Great presentation! Thank u!

Man, you teach with my style of learning and I fucking love it. The gods sent you to me. I just won the lottery, thnksxx

I dont typically comment but HOLY SH!T you really made this all click! thank you so much, you dont know how appreciative I am

Thanks for this omg I love ur explanations

perfect clarification

Outstanding explanation 👏👏👏👏Thanks a lot💟

I’m in med a school. Very good video. I subscribed

Love your vid

omg this is so incredibly helpful, thank you thank you!

Thank you so so so much! Awesome video!

So constriction of arterioles increases TPR right

good job

Thank youuuuuuuu Wow! had to subscribe!!!

Hi Dr. Mike. Thanks for all your videos...it is so helpful for my pathology courses! I was just wondering is another factor for the increase/decrease of TPR Chronic Kidney Disease ...where there is too much albumin in the blood...affecting osmotic draw? thanks

Assuming that the volume flow rate is the same velocity is a function of the area. Since the diameter has been reduced by 1/2, the area is reduced by 4. As a result, the velocity must increase by the same factor, four!, to compensate 🥴

Can you do a video on PVR?

@ Doc : theres something i dont understand : if peripheral resistance is increasing in arterioles, then according to the formula we shoud have a high BP in the peripherie which isnt the case coz its around 50-55mmHg. how come ?

As Phoebe once said : Yum My

Can my tuition just go to you instead?

Wow, I am a physiology student and this video was incredible. This topic has been made so much clearer through you guys. Thanks so much

His chest and arms are distracting (in a good way).

So a vessel can effect the bloodpressure with its diameter, length, and viscosity. Got it 😏👍

Does that mean muscle mass has a negative effect on blood pressure in the same way fat does? More fat = more blood vessels to feed the tissue. More muscle = more blood vessels to feed the tissue. In both cases the heart has to work harder

"some cyclist" haha my baby had to blood dope due to hemolytic disease of a newborn causing anemia... after exchange transfusion and ivig. this all makes so much more sense! I agree with MissAmethysmonkey, my tuition should be going to you. hopefully my constant view's translates to some $$

so at tissue level u say vasoconstriction occurs. ok , but to increase blood flow vasodilation should occur ?can u clear pls?

so if i put my finger on the end of the hose will less water will come out? Or would the same amount come out, only at a greater velocity? and if the water doesn't come out wouldn't it go to other parts of the body where the blood is needed more, not "backing up into the system"? And if you cut a garden hose in half but kept the amount of water being fed into the hose constant wouldnt the hose fill up the bucket at the same rate? ???? Just asking.

You said that increase in length will increase the svr The by this equation blood pressure =svr multiply by cardiac output Blood pressure must increase Pleassse someone help me

Thank you, Dr. Mike. If you want anything, I am in your debt, you can contact me anytime.

loved the presentation, very organized which made it really interesting as if I am watching a movie that I don't want to look away from

How can I reduce the Vasoconstriction effects from drinking Green/Black/Oolong Tea? From what I understand, “Cacao” has Vasodilation properties and most likely would potentiate the Caffeine from my Cup of Tea?! Any suggestions are greatly appreciated!

Thanks for explaining! I'm going through accelerated emt class right now..

I am curious if anyone experiencing this, I have a hard time concentrating because he is too handsome :D. Thanks for such a clear explanation. So well explained!

When we stand up (postural Hypotension) .... Does peripheral vascular resistance increases or decreases..... Please help if someone knows??

Thanks Dr. Mike, here for Advanced Pharmacology revisit!

thank you, sir, for your good video lectures, but I have a question, when I am scared my blood pressure goes down and I feel I am about to faint. why?

stupid question: do lengthened blood vessels have an overall increased BP effect by making the heart compensate for their lowering of pressure?

That was great Thank you

excelent explanation! im a student

Great video! You made this information very easy to understand. I am now a subscriber.

Not all heroes wear capes

Thank you very very much 🌷

I had been searching RU-vid past one hr to understand the concept of vasoconstriction…I hav watch near 3-4 vdos by now still My concept was getting clear. I had least expected from that I m gonna understand when I played first(actually this is my first video from your channel not a subscriber) But my goodness!! This is EXACTLY WHAT I WAS LOOKING FOR. thank you isn’t just enough man ❤️❤️

this is legit the best video i have ever seen explaining this! i never understood it til now!

You surly are a great teacher after watching this video I were able to understand more about BP and arterial.. thanks.

Super explanation

To be able to actually follow you up in a efficient way I need to sniff 1 Kg of adderal with 2 L of coffee. Just joking. amazing presentation Mate.

Thank you so much!!!!

Great Video Dr.Mike!! Thank you for the helpful information ☺️🙏

U are like Tony stark

Thank you for the breakthrough explanation.

Thank you for a great explanation.

Amazing

Awesome

I have a seminar tomorrow.....you are a great help 😊❤️

You are G.O.A.T 🔥🔥🔥 so simply explained the entire 4 chapters of human physiology in just 8 mins with such an ease.. I wish you were my tuition teacher😍

Amazing presentation of materials the dear Dr.

Thanks for making this all make sense!

Thank you!

Very helpful

thank you buff physiology guy

Thank u so much it was very helpful for me

Woooww amazing ❤️😍😍😍

Awesome explanation! Thank you!

Thank you. It helped me so much

Your videos have been helping me get high As on all my physiology exams. Thank you so much! You make it so easy to understand

I understand this so much better now. Thanks for all the examples!

What is Hybetez Remedy? I have noticed several amazing things about this high blood pressure remedy.

Thanks for the easy explanation. Just to clarify, in anaemia because the blood is thinner this would decreased SVR? Thanks

thank you, your explanation really helped me!

1000km of vessel/kg of fat tissue wtfff

I've got a question: in class we learned that R=8*n*l/pi*r^4, which means that when you increase the length, the pressure increases. I think u said it's the opposite. But i probably misunderstood something. Could you please help me with that? The video is extremely helpful anyway, you're great! Thank you so much for your work

Would be great if you mentioned the normal range of SVR and its units. I think there is a lot of confusion about that in the literature.

Very clear and highly recommended! MD

You said for every kilo of fat you put on our body you need to generate "at least a 1,000 klms of vascularity". Is that right - a 1,000 klms??

Thank you doctor ❤

im not scared of dogs, so my sympathetic nervous system will be calm

amazing . so clear. thank you!

You are amazing sir, thank you.

Awesome video!!! Thank You So Much!!!!

Dr Mike, Thanks for the videos. Hopefully, you can help me. You're a guy who obviously works out and so am I (probably not as much as you)! I'm 64 yo and play golf here in Texas. I also walk everyday. I have this problem where on warm days, golfing or exercise OUT DOORS will cause my blood pressure to crash. Normally, my BP is 130/80 and it crashes to 90/60 and as low as 85/55. I try and stay hydrated both during exercise and the days before exercise. I've seen an endocrinologists with no help. There is a mechanism called orthostatic intolerance during heat stress that fits my situation. Golfing involves a lot of bending over which seems to worsen my problem. (light headedness, etc) Should I be seeing a neurologists to help me with this problem??

Thank you muscular sir

Father Lord I thank you for this man yes because not everyone can teach 🙏. Thank you sir.

now wow, this video was fantastic

I couldn’t wait to finish watching before appreciating this video ❤

I liked this. Helped a lot! But just wondering at 6:26 do you mean heart 'has to pump harder just to get the same amount of BLOOD FLOW' instead of PRESSURE? Thanks.

Thank you so much Much love

👏👏👏 bravo. That was extremely helpful. You are the best!

I love this man❤.

Dude this is actually really Good thanks
