Could a lung collapsed cause damage?

Collapsed lung low O. A collapsed lung doesn't oxygenate blood, so a person with one feels very short of breath. The damage to the person comes from the oxygen problem. Once the lung is re-inflated, it usually goes back to working about as well as it worked before. Sometimes the collapses come in people with lung disease, so that might not be very well, but they also occur in young, tall, thin athletes.
