Case Discussion

Patient recovered and was discharged 3 days later.

Re-expansion pulmonary edema can be bilateral and fatal with a high mortality rate. Risk factors include chronic collapse of the lung. The duration was unknown in this case.

The rate of re-expansion should be limited to 1-1.5 L/hour, however the volume cannot be measured if an underwater seal is used.

Intermittent measured aspiration may prevent re-expansion pulmonary edema.
