Pressure regulation methods for positive pressure respiratory therapy
First Claim
Patent Images
1. A method, comprising:
- initiating a pressure delivered to a user at a sub-therapeutic pressure;
sensing one or more breathing parameters;
calculating at least two pressure steps from the one or more breathing parameters; and
increasing the pressure by at least two pressure steps while the user is in a state of wakefulness.

Abstract
Methods that may provide a positive pressure therapy to a user are described. The methods include detecting the user'"'"'s breathing parameters and increasing the pressure delivered to the user from a sub-therapeutic pressure to a therapeutic pressure based upon the breathing parameters.

16. A method of initiating a positive airway pressure therapy, comprising:
-
delivering pressurized air at a sub-therapeutic pressure to a user while the user is in a state of wakefulness; determining one or more breathing parameters of the user; calculating a pressure step from at least one of the one or more breathing parameters of at least one breath; increasing the pressure of the pressurized air from the sub-therapeutic pressure to a therapeutic pressure in a plurality of pressure steps; reaching the therapeutic pressure while the user is in a sleep state; and administering a positive airway pressure therapy at the therapeutic pressure during the sleep state of the user.

17. A method of initiating a positive airway pressure therapy;
- comprising;
delivering pressurized air at a sub-therapeutic pressure to a user while the user is in a state of wakefulness; determining one or more breathing parameters of the user; determining the transition of the user from the state of wakefulness to the sleep state using the one or more breathing parameters; increasing the pressure of the pressurized air from the sub-therapeutic pressure to a therapeutic pressure in a plurality of pressure steps; choosing the pressure steps based on the progression of the user from the state of wakefulness to the sleep state; reaching the therapeutic pressure while the user is in a sleep state; and administering a positive airway pressure therapy at the therapeutic pressure during the sleep state of the user.

18. A method, comprising:
-
initiating a pressure delivered to a user at a sub-therapeutic pressure; sensing one or more breathing parameters; calculating at least two pressure steps from the one or more breathing parameters; and increasing the pressure by at least two pressure steps when the breathing parameters are indicating normal breathing. - View Dependent Claims (19, 20, 21)

22. A method, comprising:
-
initiating a pressure delivered to a user at a sub-therapeutic pressure; sensing one or more breathing parameters; determining the transition of the user from the state of wakefulness to the sleep state using the one or more breathing parameters; and increasing the pressure by a plurality of pressure steps from the sub-therapeutic pressure to the therapeutic pressure while the user is in a state of sleep and the breathing parameters are indicating no apnea. - View Dependent Claims (23)
