please could someone explain the changes in intra alveolar presures, intrapleural pressures and recoil forces in a case of spontaneus pneumothorax?
thanks in advance

recoil is decreased as the lungs cannot be inflated
intra alveolar pressure decrease because lung collapsed
intra pleural pressure increased because of the pneumothorax

Recoil is elasticity

Compliance is inversely proportional to elasticity (one goes up, other goes down)

when lung deflated, it is a bleb type mass which cannot expand. It has lost compliance. So there is rather no talk of elasticity (or recoil) as there no normal resting potential to revert back to. Its not inflating!

Am I able to say, that elastic recoil is on it max? Thus, increased ?
