I've always thought that when inspiring, you decrease the pulmonary vascular resistance, and this increases the pressure gradient between the ventricles and the lung (high to low, then high to lower), leading to the accentuation of the murmurs because of increased flow.
I think the Valsalva explanation may be wrong in this video. During a Valsalva the diaphragm is pressing upwards right? If you were doing a Valsalva and you opened up your throat you would immediately exhale, which means during the maneuver the diaphragm should be moving or pressing upward right?
I think were i get confused is that by compressing the veins you are reducing the compliance and thus increasing the venous return. But I understand now. Thanx.
Hopefully you worked this out, but I think it is primarily the increased systemic afterload that increases the LV pressure enough to overtake the pressure in the RV (which is hypertrophic). Then there is less deoxy blood going from the RV out the aorta and probably less cyanosis? I'm thinking of the concept kinda like the reverse of eisenmenger's, but maybe that isn't the best analogy.
Dude, God BLESS YOU; I'm studying for step rn and thankfully found your channel in my middle of studying!
Damn, you're the BEST 😍 Please do more of these, we really need them!
never understood it till now !
big thanks to you !
same here :)
You just make my life easy. Thank you.
Valsalva has never been explained so simply thank you so much!
Glad you liked it!
hey what about passive leg raise and hand grip you just closed without saying good bye

thank you! this video was so clear and cute
Amazingly easily explained concepts

Perfect explanation. Easy and very digestible😁
This was incredibly helpful, thank you so much!!!
Brilliant!

Big thanks ❤
could someone explain the bit at the end, how does squatting increase the blood flow from left to right

Very good video!
Thanks a lot❤️
nice explained! Thank you! :)
i love your drawings
Amazing!! thank you..
thank you can u please explain handgrip
Yeah, we need how hand grip causes every backward.
Thank you
increasing abdominal pressure by breathing pumps the blood to an area with less pressure - the thorax - increasing preload ** not decreasing.
Thank you so much
thank you.
Very helpful thanks
Great. Just missed the hand grip
FABULLOUS......
Squatting makes venous return less
