Great video MedCram. I can measure this diffusion capacity for the lung in clinical practice in the respiratory lab. This is very helpful in diagnosing disease causing hypoxemia and breathlessness. I’ll demonstrate this in a video soon as it complements your physiological explanation

Very nicely explained. I liked this video. This is Anthony from Santacruz, Mumbai, India.

Your are amazing thank for making things easier ♥️

Thank You.

How about the cut off of Aa gradient between VQ missmatch, shunt, and diffusion? We know that Aagradient will increase due to that disorder

It seems like there are two distinct (and conflicting) definitions of "shunt". In another video, you define a pulmonary shunt as a situation where blood is being diverted away from / around alveoli / lungs, i.e going from right heart to left heart without getting oxygenated. Here, shunting is defined as perfusion without ventilation, and deadspace is ventilation without perfusion. If anything, the first definition of "shunt" (diverted blood flow) sounds more like deadspace (ventilation without perfusion) than the second definition of "shunt" (perfusion without ventilation). Can you clarify? Thanks.
