- Dr Mike explains the various factors that contribute to blood pressure.
These include; cardiac output (CO), heart rate (HR), stroke volume (SV), preload, afterload, contractility, and systemic vascular resistance (SVR).

It was all about the moustache for me but I must say I have learnt something tonight. My brain is smiling 😊. Thank you Dr. Mike. You’re always a delight to watch.
Thank you!! 🤗
Well after trying to wrap my brain around a textbook chapter several times, it's finally clicked with your video haha THANK YOU.
Studying for Cardio/Resp Physiology exam, and this is a big lifesaver! Thank you so much for your videos :)
You’re the best Dr! I learned so much about A&P. You make everything easier to understand. Thank you! 🤗❤️
Thank you so much for this lecture! I've always been confused regarding Preload/Afterload. You made everything so easy to understand. The illustration and writings also helped a lot with your explanation.
I've just come here after i watched hypertension video from 2016 and it seems Dr.Mike has changed a lot
😝Ive got a moustache now!!
for sure but there is one thing is never gonna change is that your amazingly helping videos.Thank you sir!
Short, concise and precise
Great stuff
Thanks, Dr for making learning interesting
After 20 years i will tell my students and my sons about you doctor .. you are super helpful .. god bless you ❤🙏
Thank you so much for your videos! It’s taken a lot of stress off my shoulders knowing I can refer to them when I’m not understanding my lectures!
Love all the videos. Has really assisted my nursing studies.
Amazing, amazing video. Love the way you explain things. Don't stop making videos!
Persons with brainss Looks Confidence style + A Doctor and a wonderful Speaker woahoo U r a Package
Learned it completely
Thankss
A Great simplified explanation of many contributing variables underpinning blood pressure control. Well done. N.B. I like the moustache 👍
Spoken and explained clearly in plain English without complex medical jargon: superb. Many thanks.🙏☀️🇬🇧👍🫀🙏
you just helped me pass my anatomy test! thank you
The lecture was very beautiful. Keep going, Dr. Mike. And the moustads are very frankly beautiful. Thank you.I'm one of your followers from Iraq.
This is excellent! Thank you Doctor!
Mate you're a bloody saint. Great vid
Brilliant video as always thanks so much !
Thank you for simplifying this!!
Thanks dr for very informative lecture
Love from bagdad
Amazing explanation
Fantastic video!
Thanks a lot for explaining this !! ❤️
Thank you Dr. Mike
Making a petition to send you both to England so you can teach me :D I love your content! Thank you so much!
I've just started learning about cardiovascular physiology and I immediately clicked when I saw the video. Good job guys!
Thank you! I hope it helps!! 😊
Best explanation 👌
Presentation was crystal clear Dr. QUESTIONS: Q1: I can do an aerobic exercise at my maximum heart rate of 160 BPM for one hour. Resting heart rate is about 60 - 70 BPM.
Q2:. My cholesterol was in 200 - 220 for about a year. Now it is down.
My Linisopril is no longer working even at 30 m.g. Please give me an idea and the possibilities of why my BP is going in the Red Zone or High? Thanks
Very lovely teaching
Nice explanation
I love this man 😔❤️🙏🏻
Thanks a lot Dr, very understandable
great video thank you Dr. I'm currently taking my A&P class this helped a lot! one question my grandmother takes medication but is not helping with lowering her blood pressure. Her dr has tried changing the medication & doses. Do you have any recommendations on another way of lowering blood pressure?
Good work doctor Mike is it possible you prepare lectures on cvs and medical disorders
Dr. Mike, thank you again for another excellent lecture!! Critical Care Nurse here... two quick questions to better my understanding. First, I know some teachers who state the CO formula as (Heart Rate + Heart Rhythm) x SV.... what is your take on teaching it this way? Is this valid or overly complicated for the average understanding? I'm guessing the typical formula is assuming Sinus Rhythm, but perhaps this is incorrect? If arrhythmia is accounted for, would this typically be negatively affecting preload and/or contractility.... as in A-fib decreasing preload via dysynchrony of atrial contraction or SVT decreasing preload via reduction in diastolic filling time. Second, I'm trying to better differentiate "Afterload" from "SVR".... many seem to lump these together, but obviously this formula assumes they are distinct. I know that increased SVR increases afterload, but after that I'm a bit lost. Thanks for all you do and share!!
Thanks for your great explaining, Please talk abou thymus gland
We will!
@@DrMattDrMike Thanks alot
Thanks. But when the SVR decreases the CO will increase! Why the BP won’t increase? And can we say SVR is the same as afterload?
You are a legend
Same look like W. F. Nietzsce become clear. Thank you Dr. Mike. your lecture perfect balance
Nietzsche’s moustache was next level!
Thank you so much!😍
i'm vietnamese i love your videos
Very useful
Can you do a quick video on how albuterol may be harmful in causing VQ mismatch?
Hi Doc Mike,
I love you 💕 Mustache 😅!!love From Pakistan 🇵🇰!
And thank you for the precise and short brief lectures! Keep Going Sir ❤

Thank you
Cheers and happy Movember!
well and thanks sir😘❤
Nice explanation 👌 and Nice mustache 🙂
My god, thank you
Thank you sir 🤗
That moustache😅
❤❤❤❤❤❤ thank you

Afterload and vessel constriction seem to contradict themselves, in terms of their effect on BP. That is, wouldn’t a constricted blood vessel increase afterload? If so, how can increased afterload decrease BP? Could you please clarify?
Increased afterload will initially decrease stroke volume BUT the myocardium will overcome this by INCREASING contractility in order to overcome.
Increased arterial Vasoconstriction will result to an increased flow resistance or afterload consequently Stroke volume (blood flow volume) will be reduced. The same principle of Karcher pressure cleaner, when the resistance to the flow is high (vasoconstriction), the volume on the outlet (Stroke Volume) will be decreased but the pressure within is increased. The same anomaly of the water pressure cleaning - less water usage (Stroke volume down) but high pressure water flow (blood pressure up). Hope that’s help.
First to comment 😀😀I’m hypertensive and have been on metoprolol and benicar
👋
Wow really 💎💎
Good
Great video! 😊 Also, you're very handsome 😶
I wish I saw this before my exam 😭😭😭😭😭
What can we do to keep blood pressure low and heslthy
Hey I'm 24 worh very high blood pressure (170/98 on average) and medication doesn't agree with me tried 4 times and each time I've ended up in hospital after 2 weeks of feeling ill and means I cannot function and get on with every day life. I've heard loosing weight will reduce my blood pressure (which seems to be difficult no matter how much of a calorie defect I'm in or how much exercise I do etc..) But what I want to know is. How does weight play a role in blood pressure? I'd assumed it was cholesterol if anything as this clogs arteries etc (my cholesterol is healthly range) but how does your weight play a part in blood pressure? could you please explain this in a simple terms as I'm trying to understand other options other than medication to lower my bp. Thanks x
Reduce salt intake to very low and drink more water also. And also do exercises and eat healthy food which are non toxic to the body . With then try to reduce medications when you get healthier
You said the Las Vegas nerve?
Silly q - so is constant caffeine consumption bad for the heart? like over a lifetime - am I making the heart work too hard with daily caffeine consumption?
🙏🏻🙏🏻🙏🏻

👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
¿Is it true that LBP (low blood pressure) can kill u faster than HBP (high blood pressure)? Assuming no combat penetrations, what measures are available to (non-medical folks) when observing otherwise healthy non obese individuals w say a BP of 84/60 complaining of dark rectangular grid spots in the field of vision.
Thx for helping us learn the basics of life science. Oh yes, ur mustache is very funny as it makes ur lateral eye lines twinkle. Very clever....
Hi Mike , ❤️❤️❤️ thanx for your help 💕✨🙈 Hope u see my comment , a Heart from u Can make my day leterly 💕
Can't belive it 😭😭😭🥺✨THANK U ❤️❤️❤️❤️❤️
Got it Dr . & You look like typical Indian with moustache shirt & wrist rope . Looks cool 😎
