Mean Arterial Pressure (MAP) Calculation Formula Explained Nursing

Mean arterial pressure (MAP) calculation formula explained for nursing students and nurses.

What is a mean arterial pressure (MAP)?

Mean arterial pressure is the pressure in your arteries during one cardiac cycle, and it tells us how well the vital organs (like the renal system, brain etc.) are being perfused. In addition with the brain, the MAP is very important when calculating the cerebral perfusion pressure.

The MAP should be greater than 65 mmHg.

Normal 70-100 mmHg

Hello Everyone :) Thank you so much for watching the video. Don't forget:

I just wanted to say thank you for taking the time to make these videos. These videos helped me achieve my 25 year dream to become a nurse! I have listened to all your videos throughout my classes and this NCLEX Review was perfect for my exam.The endocrine is my favorite! Extremely helpful for my NCLEX exam on Tuesday Feb 6th, 2018.I found out today I passed!! I have told all my classmates who are still in class to watch your channel. Keep on making these awesome videos! You’re making some great nurses <3

Wow thanks for explaining in 2 minutes what my professor managed to drag out for 45 and confuse everyone

Dear Mrs. Sara, i am pleased to inform you i got the good pop this afternoon! I have been watching your videos all through school and this morning before the NCLEX. The nursing world definitely needs more teachers like you! Thank you for your good work!

I love you and I don't even know you> currently a third-semester student. I started watching your videos since I started the program and you cant imagine how much I appreciate your time to make these videos! I always say that I am surviving nursing school because of you.

Thank you so much!! I was struggling to learn it until i watch your video explaining it way better

Thank you didn't know hoe to calculate it or what it was.
Your are the real MVP

In case you guys are mathematician doctors, then this equation is derived from the Linear Interpolation (aka. lerp),

Originally:
Since,
f(x) = y = mx+c (equation of straight line).

Then, recall two points (x0) and (x1), then

Δy = y1 - y0 = (m x1 + c) - (m x0 + c) = m (x1 - x0).

Then, (m) designate a scalar multiple of (x1 - x0).

Then, f(Δx) = m (Δχ) + C ;where C denotes the vertical distance from the initial position (reference point).

Since, for most of the cardiac cycle the blood pressure is (1/3) times the pulse pressure...

Then,

f(Δχ) = m (x1 - x0) + C

MAP = scalar * (SP - DP) + DP

Graphically, this could be a point between 2 points on the same straight line, or a point between 2 parallel straight lines (the graphical representation of the arterial pusle from the physiology textbooks)...

Very cool! Isn't it?

Why couldnt my a+p2 textbook explain it like this 😭 thank you sm

Hey Sarah! Thank you for all of your help and advice. I am a sophomore nursing student and always go to your channel when I need help with a subject. Can you do a video on seizures, seizure meds, and seizure precautions? Thank you!

[Lexusfordd]

Thank you this was so easy to understand!!

[poohsaccoolerhelicopterwal]

Thanks ma'am....tysm for solving my queries regarding it

[Linkfan]

can you please do a video that explains the FULL pathway of MAP in how cardiac output, Total Peripheral resistance, and system all come together? This is for my Physiology class. Please?! Thank you!

Hi Nures Sarah, thank you so much for your videos. You don't have no any idea how much help you are to me and to a lot of nurse hopefuls. <3

[kclynn]

Very helpful. Quick and to the point! Thank you - Casey GN

[rejeevejacob]

Thank you.8
I left the medical sales field long ago.the days I watch your channel and is helped.I tell you you could be a christian preacher and help others, as you seem to have transparent which most preachers lack.may God bless you

Hi Sarah, very informative. Good news, my MAP is 80, BP was 106/67 so 67x2=134+106=240/3=80. Not too shabby for a 70 year old dude, lol. Thanks for the video! Just curious, do doctors look at the MAP as a more accurate measure of high blood pressure over say the traditional BP measures, i.e. systolic over diastolic.

Such a helpful video, thank you so much!

[saraskinner]

Hi! I love your videos !! Would love to see a video on encephalitis and meningitis (unless there is one and I can find it!!! Thank you so much (getting me through last semester of nursing school!!)

[palomacasib]

hi mam sara...☺️😀all your topics are very helpful.. thank you so much🤗.. i love the way you simplified things because its easy to understand.. do you have central venous pressure topic? hemodynamic montoring too?
