It is binding but sometimes essential machine, which helps people who suffer from sleep apnea, sending compressed air at a continuous pressure and constantly above atmospheric pressure in the airways, by means of a nose or face mask connected to a pump. The flow of air creates enough pressure during inspiration to keep the airway open

The system has a remarkable efficiency (in terms of cardiovascular mortality) when the air pressure in the airways is sufficient to overcome the obstructions and / or to stimulate normal breathing.

Although CPAP is considered the standard treatment for obstructive sleep apnea (if it is well tolerated by the patient), it is a very constraining treatment. This CPAP mask must be worn every night to be effective.

This is the standard treatment, but increasingly controversial of sleep apnea. Its constraints and unjustified requirements may make better the use of nasal dilator RespiFacile.

CPAP has side effects: skin irritation by an incorrect mask, rhinitis or sinusitis, conjunctivitis by leaking mask irritation. PPC can have more rare, but serious side effects: epistaxis (nosebleed), pneumothorax, cardiac arrhythmias.
