摘要:
A pressure driver for a ventilation system comprises a gas source, an inspirationflow control valve and a patient pressure sensor to form a closed loop controlsystem. The inspiration flow control valve may be mounted within a housing andis operative to open and close in response to patient pressure measurements inorder to produce a desired pressure at the patient. The pressure driver may furtherinclude a mixture control for allowing selective adjustment of the oxygen concentrationin pressurized gas delivered to the patient. An oxygen mixer is connected betweenthe gas source and the mixture control and is operative to deliver the desiredmixture of oxygen and air to the inspiration flow control valve for delivery tothe patient. An oxygen sensor monitors the oxygen concentration in the gas providedby the oxygen mixer.
