    Zach,
    I'm a Term 1 medical student and I just want to stop by and tell you how much I appreciate all your videos. I'm on my last week of the first term and we have our CPR2 exam coming up and your videos have clarified so many points in their lectures. A year ago my father died from a massive pulmonary embolism. As you can imagine, its very difficult for me to listen to these concepts and understand just how much he went through during his final moments. He's my sole motivation for becoming a doctor. I hope I can make him proud in the years to come but as of right now I've been able to accomplish that thanks to you and your channel! I look forwards to watching many more of your videos throughout my medical school journey. Thanks again!!!

    intermediate ventilation.

    At time 27:30, you said that ventilation decreases from apex to base, but actually it increases from apex to base of the lung. Perfusion also increases from apex to base, but much more significantly that we have a lower V/Q at the base.

    There is an error: ventilation is higher at the base than at the apex because of increasing compliance.
    The V/Q ratio is biggest at the apex because at the apex: Q higher is relatively to V.
    V/Q ratio is lowest at the base because V is higher comparatively to Q.

    Hey Zach, great video but wouldn't V AND Q be greater at the base compared to the apex (~28:00)? Pa > Pv > PA in Zone 3 so arteriolar perfusion pressure leads to good blood flow. For Ventilation, alveoli at the base have higher compliance and we would see an increase in ventilation for Zone 3 as well. Overall the the increase in Q > V so V/Q is decreased even though both are increased
