A member asked:

What happens that causes pneumothorax to cause heart to stop?

A doctor has provided 1 answer

Blood flow: All blood from the right side of the heart go to the lungs, oxygenate then go to the left side of the heart to be pumped to the rest of the body. In pneumothorax, the collapsed lung has high pressure due to collapsed arteries and put too much strain on the right side of the heart to overcome, less oxygenation, and the heart may not be able to do it and it stops pumping.
