Augments inspiratory/expiratory pressures throughout a spontaneous respiratory cycle.
Recruits compressed alveoli to reduce atelectasis.
Prevents small airway collapse during inspiration.
Counteracts intrinsic PEEP (Positive End Expiratory Pressure).
Decreased both preload and afterload in heart failure exacerbations.
Improves lung compliance and V/Q matching.
Decreases the work of breathing.
Reduces need for intubation and mortality in acute cardiogenic pulmonary edema and acute COPD exacerbation

CPAP = PEEP = EPAP
Use for isolated hypoxia
Increasing CPAP increases oxygenation
BPAP = PEEP + (IPAP = Inspiratory Pressure Support)
Use for hypoxia and hypoventilation (decreases work of breathing)
Increasing IPAP (specifically IPAP-CPAP) increases<unk> 
Note: BiPAP is a brand name of one of the BPAP machines. Both names are often used interchangeably.
