In ARDS which pneumocytes are destroyed? I, II, or both


In FA the pulm chapter under hemoglobin section it says that hemoglobin exhibits positive cooperativity and negative allostery. Shouldn't it be positive allostery?

The negative allostery is in regards to 2,3 bpg,
For ards, for adults its diffuse damage, but for neonates its mostly type 2.

I could totally be wrong..but for ARDS I thought it was both..but overtime you get type 2 proliferation
