Definition Return to top

CPAP stands for "continuous positive airway pressure." CPAP is a treatment that delivers slightly pressurized air throughout the breathing cycle. This makes it easier to breathe. CPAP can be used by mouth, by nose, or through breathing tubes.

Information Return to top

Nasal CPAP is given through a mask that is placed and secured over the person's nose or nose and mouth. Slight positive pressure is used to increase the amount of air breathed in without increasing the work of breathing.

CPAP is useful for children with collapsible airways, small lung volumes, or muscle weakness that interferes with adequate ventilation.

CPAP is also used for adults with COPD, acute respiratory failure, and sleep apnea.
