Abstract
A CPAP device includes an air stream generator for generating positive pressure, a face mask connected to the air stream generator through a flow supply catheter, a pressure sensor measuring pressure in the face mask, a control circuit controlling the air stream generator, and a pressure detection pipe having a first side and a second side. The pressure sensor is connected to the second side of the pressure detection pipe to measure pressure of the detection hole formed at the first side of the pressure detection pipe and outputs the measured pressure value to the control circuit. The control circuit distinguishes average positive pressure from pressure caused by spontaneous breathing of patient according to values of the pressure in the face mask, which are input from the pressure sensor, and controls a speed of the air stream generator such that preset positive pressure is supplied to the patient.
