CPAP
Definition:
CPAP stands for "continuous positive airway pressure." CPAP is a treatment that delivers slightly pressurized air by the use of a machine and mask or tube system. This keeps the airway open and unobstructed. CPAP, which is a treatment for sleep apnea, delivers air throughout the breathing cycle while the patient sleeps. This makes it easier to breathe. CPAP can be used by mouth, by nose, or through breathing tubes.
Alternative Names:
Continuous positive airway pressure; CPAP
How the treatment is performed:
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. It uses air pressure to push the tongue forward and open the throat. This allows air to pass through the throat. It reduces snoring and prevents apnea disturbances.
CPAP is useful for children with collapsible airways, small lung volumes, or muscle weakness that interferes with adequate ventilation. It is also useful for those who are morbidly obese.
CPAP is also used for adults with COPD, acute respiratory failure, and sleep apnea.
For those individuals who have obstructive sleep apnea the windpipe that brings air into the body is blocked during sleep. This keeps the lungs from getting enough air. People who have sleep apnea stop breathing for 10 to 30 seconds at a time while they are sleeping. These stops can happen up to 400 times every night. The consequences of these disturbances can be serious and sometimes life threatening. A CPAP device does not cure sleep apnea. But, when the device is used correctly, sleep should improve. Research suggests that untreated sleep apnea may contribute to high blood pressure, heart disease and increased risk of traffic accidents due to daytime sleepiness.
