Pressure Sensor use in CPAP Machines for Sleep Therapy

Pressure sensors play a critical role in CPAP machines by monitoring the flow of a continuous positive airway pressure (CPAP ). This light air pressure from a CPAP machine helps make sure your airway doesn’t close and interrupt your breathing as you sleep.

The CPAP machine has a small motor that blows air into a tube that connects to a mask that covers your nose and mouth, or in some cases just your nose.
