Abstract:     Method for automatic stop-start control of a breathing apparatus. Automatic starting and stopping of the device based upon the determination of a user wearing the mask by way of proximity sensors determining that a user is physically in contact with the mask in order to start the device and stopping the device when the proximity sensors determine the user is not in physical contact with the mask.

CROSS-REFERENCE TO RELATED APPLICATION
    This application is a divisional of copending application Ser. No. 08/347,552, filed Nov. 29, 1994.

Designated Country: DE FR GB 

Family: Show 7 known family members

First Claim:
Show all 5 claims
What is claimed is:     1. A method for controlling an apparatus for the administration of continuous positive airway pressure (CPAP) treatment, the apparatus having a controllable flow generator coupled to an air delivery circuit, in turn coupled to a mask for the supply of CPAP treatment to a patient's airways, the method comprising the steps of:
  • determining that the patient is wearing said mask, and if being worn controlling commencement of the administration of CPAP treatment by activating said flow generator, said determining steps comprising:
    • (a) detecting flow of air in said air delivery circuit;
    • (b) detecting a pressure change in said air delivery circuit; and
    • (c) detecting proximity of the patient's face with said mask.
