How do CPAP machines work?

CPAP machines provide pressurised air in your throat via an air pump that is attached to a mask that covers your nose, nostrils or the mouth.

A sleep apnea machine provides pressurised air in your throat via an air pump that is attached to a mask that covers your nose or nostrils, or sometimes the mouth. The air pump and mask are linked by a tube that is attached to an airflow generating machine.

For someone diagnosed with sleep apnea, the machine acts as an air splint to keep the throat open, which is collapsing multiple times every hour during sleep causing them to choke or stop breathing.
