CPAP and Respirators  

Continuous positive airway pressure (CPAP) helps patients breathe by holding open the alveoli and preventing them from completely collapsing during expiration phases.

The most important aspect in a CPAP system is the air flow control that needs to be adjusted to compensate for altitude, mask movements, and leaks as well as features including heated, humidified, airway respiratory support.

ST’s motor control ICs help implement very accurate motion profiles with reduced acoustic noise to improve comfort to patient. In addition, we provide a range of MEMS motion, pressure and humidity sensors, high-performance STM32 microcontrollers as well as high-precision operational amplifiers and low-power regulators to help develop advanced CPAP ventilators.
