Very helpful, happy to find your video; thank you!

Great Works .Thank you so much

Enta ma’alem!! Thank you so much for your time.

Thank you!

Excellent series of lectures, thank you Dr.Hanna , you make it look very simple

[@gauravpandey7636]

Thank you sir…..kindly put a detailed lecture also in near future…🙏🙏🙏

I may, hopefully. Meanwhile, consider watching my other shunt discussion video, where I also have more complex cases, including calculations in bidirectional shunting:

Also, consider watching the portion of this video that discusses the difference between SVC and IVC O2 and what is the best chamber to sample upstream of a shunt for Mixed venous O2:

Timeline 14:30: The Formula to calculation PVR ist wrong, should be: PVR = (mPA-PCWP)/Qp.

[@eliashanna8248]

True, correct, thank you. I explain PVR equation more in details under 3 other videos, including the detailed pulmonary hypertension video: th-cam.com/video/Vd7emZcvj0g/w-d-xo.html (minute 07:20), and the cardiac output videos such as th-cam.com/video/VbmoHuCAYqY/w-d-xo.html (minute 46:05). The point we're trying to make here is to use Qp in the PVR equation whenever there a shunt, (Qp derived from Fick equation), not Qs and certainly not thermodilution cardiac output. Nonetheless, the PVR equation was inadvertently inverted.
