Method for acclimating a CPAP therapy patient to prescribed pressure
First Claim
1. A method for controlling startup of CPAP apparatus which applies an IPAP pressure to a patient'"'"'s airway during inhalation and an EPAP pressure to the patient'"'"'s airway during exhalation, said method comprising the steps of applying a therapeutic IPAP pressure to the patient'"'"'s airway during a startup period, and at the beginning of the startup period applying an EPAP pressure below the therapeutic IPAP pressure to the patient'"'"'s airway and increasing the EPAP pressure to the therapeutic IPAP pressure during the startup period.

Abstract
A method for acclimating a CPAP therapy patient to a prescribed pressure while the patient falls asleep. During an initial startup period, the CPAP apparatus applies a therapeutic IPAP pressure to the patient'"'"'s airway and a lower initial EPAP pressure to the patient'"'"'s airway. The EPAP pressure is ramped up to the IPAP pressure over a sufficient time for the patient to fall asleep. In a modified embodiment, both the initial IPAP pressure and the initial EPAP pressure are less than the prescribed therapeutic pressure. The IPAP and EPAP pressures are then independently ramped up to the prescribed therapeutic pressure.

- 4. A method for controlling startup of CPAP apparatus which applies an IPAP pressure to a patient'"'"'s airway during inhalation and an EPAP pressure to the patient'"'"'s airway during exhalation, the patient having a predetermined therapeutic airway pressure for reducing or eliminating the occurrence of abnormal sleep events, said method comprising the steps of initially applying an IPAP pressure to the patient'"'"'s airway which is less than the predetermined therapeutic pressure and applying an EPAP pressure to the patient'"'"'s airway which is no greater than the IPAP pressure, during a startup period increasing the IPAP pressure along a first trajectory to the predetermined therapeutic pressure, during the startup period increasing the EPAP pressure along a second trajectory to the predetermined therapeutic pressure, wherein said second trajectory is different from said first trajectory, and wherein the EPAP pressure does not exceeds the IPAP pressure during the startup period.
