How do chest tubes work to fix a collapsed lung?
I am not in the medical field. But if a lung collapses it means
that there is air getting between the lung and the chest cavity
creating pressure against the lung. A tube placed in the chest wall
will relieve the pressure there. When the lung fills with air it
pushes the air out of the tube. Then you can block the tube to give
the chest cavity back the slight vacuum it had before. That is why
your chest expands when you breate in. I hope this is right and I
am not stepping on any toes out there.
