Abstract: This application note introduces how a continuous positive airway pressure (CPAP) ventilation system operates. The main subfunctions of CPAP respiratory ventilation include air-hose-environment sensing, compressor motor-drive feedback, motor-drive excitation, and a communication interface to a technician/doctor. These subfunctions are explained and a functional block diagram showing system components is also detailed.
