Delivering perfluorocarbon to the lung is a tedious procedure. The drug must be slowly dripped into the airway to avoid obstruction by air locks in the distal lung. Hypoxemia, tachycardia, and hyper or hypotension are common during filling if care is not exercised.

Repeat dosing is required every 2 to 4 hours to maintain an appropriate drug level.
