摘要
The present invention discloses both a method of operating CPAP apparatus, and the apparatus itself in which a breathable gas delivery device or mask (1), is connected to a gas supply pump (14) via a conduit which includes a restriction to gas flow such as a small bore portion (3). A pressure transducer (11) is used to sense the gas pressure at the patient's nose and the transducer output is used to servo-control the pump (14) to maintain the sensed pressure substantially constant.
