Advantages and disadvantages of the different methods for administering positive airway pressure

Mode of positive pressure ventilation	Advantages	Disadvantages
CPAP	Inexpensive	Lack of inspiratory pressure support
	Widely available
Bi-level	Widely available	Tidal volume may be limited by patient-related factors
	Can provide inspiratory pressure support to augment tidal volume
	Leak tolerant
Volume-cycled	Can set specific respiratory parameters	More expensive
		Less widely available
		Less well tolerated than pressure support devices
		Leaks lead to loss of tidal volume

CPAP: continuous positive airway pressure.
