CPAP, ventilators, and respirators

Continuous positive airway pressure (CPAP) helps patients breathe by holding open the alveoli and preventing them from completely collapsing during expiration phases.  The most important aspect in a CPAP system is the air flow control that needs to be adjusted to compensate for altitude, mask movements, and leaks as well as features including heated, humidified, airway respiratory support.
