Acclimatization therapy for first time CPAP and NIV users
View Patent ↗A method of acclimatizing a user to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB) during successive treatment sessions, wherein the device provides continuous positive airway pressure during sleep, includes determining a clinically-derived full therapeutic pressure, applying a sub-therapeutic treatment pressure for the duration of a first session, obtaining responses to a series of pre-programmed patient and/or bed partner feedback questions before the start of a second session, and, based on the responses, either incrementally increasing the treatment pressure for the second session if the responses indicate that the patient is adjusting to therapy, or maintaining the treatment pressure for the second session if the responses do not indicate that the patient is adjusting to therapy.
1. A method of acclimatizing a user to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB) during successive treatment sessions, wherein said device provides continuous positive airway pressure during sleep through a mask, the method comprising:
determining a clinically-derived full therapeutic pressure;
applying a sub-therapeutic treatment pressure for a duration of a first session;
obtaining responses to a series of pre-programmed patient and/or bed partner feedback questions before a start of a second session; and
based on the responses, either incrementally increasing the treatment pressure for the second session if the responses indicate that the patient is adjusting to therapy, or maintaining the treatment pressure for the second session if the responses do not indicate that the patient is adjusting to therapy.
2. The method according to claim 1 , wherein the sub-therapeutic treatment pressure is below 4 cmH 2 O.
3. The method according to claim 1 , further comprising allowing the patient to become accustomed to wearing the mask during sleep before the first session.
4. The method according to claim 1 , wherein the feedback questions are displayed on a display of the device.
5. The method according to claim 1 , wherein the feedback questions include yes/no questions, a rating out of ten questions, treatment comfort questions, and/or patient restlessness and sleep quality questions.
6. The method according to claim 1 , further comprising repeating said obtaining responses and incrementally increasing the treatment pressure for subsequent sessions if the responses indicate that the patient is adjusting to therapy until the full therapeutic pressure is reached.
7. The method according to claim 1 , wherein the treatment pressure is incrementally increased by 1 cmH 2 O.
8. The method according to claim 1 , further comprising monitoring the patient during the treatment session to provide a signal of patient compliance.
9. The method according to claim 8 , wherein said monitoring is used along with the responses to determine whether the treatment pressure is increased.
10. The method according to claim 1 , wherein the method is carried out over five or more daily treatment sessions until the full therapeutic pressure is reached.
11. The method according to claim 1 , further comprising preprogramming a profile of increasing treatment pressures and/or initial treatment pressure into the device.
12. The method according to claim 11 , further comprising preprogramming limits of adjustment of the profile in response to patient responses.
13. The method according to claim 11 , wherein programming is conducted by a clinician.
14. The method according to claim 1 , further comprising displaying a message on the device that advises the patient to contact a clinician and/or directly notifying the clinician upon a predetermined number of negative responses to the feedback questions.
15. The method according to claim 1 , further comprising incrementally increasing the treatment pressure until a preset percentage of or pressure differential from the full therapeutic pressure is reached, and holding the pressure for a predetermined number of days to monitor patient respiratory events.
16. The method according to claim 1 , wherein the successive treatment sessions occur on different days and the first session and the second session are on different days.
17. The method according to claim 1 , wherein the sub-therapeutic pressure is a pressure that does not provide an optimum therapeutic benefit to the user relative to sleep disordered breathing.
18. The method according to claim 1 , wherein the device is powered off between the successive treatment sessions.
