Hi I have some points that I don’t understand: -When the blood flow to the RA due to pressure difference the RAP increases till the point where there is no venous return or stop at 2 mmhg for example where VR and CO are the same ? Or the pressure during the one minute doesn’t change ( all the time 2 mmhg )
On page 247 ohm's law states that an increase in arterial pressure will increase CO. Why, then on page 248, is increased arterial pressure a cause of a hypo effective heart? Wouldn't an increase in arterial pressure lead to an an increased CO, and then a hypereffective heart?
In the setting of a hypoeffective heart, the heart struggles to push blood through the aortic valve leaflets. This can occur if there is a greater force keeping the aortic valve leaflets closed (i.e. systemic hypertension or high arterial blood pressure) making it harder for the heart to work as a pump and become less effective (hypoeffective heart). The Ohms law equation is confusing as it just states "arterial pressure", when this is actually representing the pressure gradient between the left ventricle and Aorta (NOT just aortic pressure). So if you increase the pressure gradient between the LV and aorta you will increase cardiac output, but if you decrease the pressure gradient between the LV and aorta (by increasing aortic pressures; i.e. systemic hypertension) then you will reduce cardiac output. I hope thats not too much "bro" science

Thank you so much! I’ve been stuck reading this chapter for hours and now it totally makes sense 😭 God bless you
That is amazing Ren, Glad to be able to help
Just shared your channel's link on all my UNISA groups. Hope it helps your channel. This has been immensely helpful to me. Keep up the awesome work.
Thanks Leah! Appreciate the support and glad you find it helpful
You're officially my fav UA-camr!
Thanks B Srna!
Thanks alot dude ❤
Just subscribed the channel and shared this channel with my class group. Please keep making videos
Thanks Haseeb! Greatly appreciate the support
Sir, in fig 24 what arterial pressure means.... Is it pressure of artery or atrium
Frm Nigeria,Thanks for the videos....we wil realy appreciate it if u cn post other chapters of the book...i find them useful n concise🙏
Thank you for the feedback!

what exactly is the frank starling law?
the amount of blood that will be pumped by the heart, depends on the venous return.
Ch 20 is erythropoiesis right¿

@@StudyThis That makes much more sense. Thank you!
Perfect, thank you!
Can u do McLeod book for clinical skills I will be so happy really I need it
I am corona class they didn’t teach us clinical skills I am lost really
Thx!
Thank you
Why they are taking normal cardiac output to be 12 litre...... isn't it 5 litre.🙄
it can be increased according to d demand😁
@@walijan57 oh!!!!btw I have cleared my first year 5 months back.....but still thank you for your explanation 🐒
@@dreamer_7112 thats good.😊
الله يسعدك❤️❤️❤️❤️❤️
