About 20 years ago I suffered a pair of spontaneous pneumothorax episodes in fairly quick succession (a few weeks apart. The 1st time they re-inflated and called it good. the 2nd time was followed up with an in-patient arthroscopic procedure to re-stick the lung, in my best layman’s understanding. It was awhile back, but I vividly remember the very intense fear of hitting on 1 cylinder.
The answer seems obvious to me, but to what degree and… maybe not? IANAD.
