expected value poorly explained
The following seems contradictory. "For every decade a person has lived, their A–a gradient is expected to increase by 1 mmHg. As a quick calculation, a normal A–a gradient is less than the (patient's age divided by 4) + 4." If you're counting decades you'd be dividing by 10, not 4. Sources suggest 4 is the correct number, I cannot find the decade detail mentioned in the sources. I'll change 'quick' to 'conservative' as in the cornell reference. If no one answers this in the next few months I may remove the decade detail. Millionmice (talk) 01:25, 23 February 2013 (UTC)

left to right shunt
It's written that left to right shunt is physiological and giving hyperlink to the cardiac left to right shunt which is pathological. The hyperlink should be removed.

Referring to the drainage of the smaller bronchi and alveoli, I hope that you would be able to elaborate further about the topic. I wonder how would such drainage be labelled as left to right shunt. Thanks, Husam.abayechi (talk) 20:48, 14 March 2020 (UTC)
