  • Publication number: 20230347084
    Abstract: 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.

  • Patent number: 11730906
    Abstract: A method of acclimatizing a patient to provide continuous positive airway pressure (CPAP) therapy, including operating a device for treating sleep disordered breathing (SDB). The device provides continuous positive airway pressure to the patient during sleep via a mask configured to provide a seal with respect to airways of the patient. The method comprises applying full therapeutic pressure during a first session, monitoring a mask pressure during application of the full therapeutic pressure, calculating a difference between the full therapeutic pressure and the mask pressure, comparing the difference to a threshold representing an acceptable level of leak, generating a first signal in response to said comparing, and in response to said first signal indicating a fault in the seal, decreasing an applied pressure to below the full therapeutic pressure during the first session in order to improve the seal of the mask against the patient's face.

  • Patent number: 10758690
    Abstract: A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes applying a treatment pressure to a patient, monitoring the patient for speech output, generating a signal in response to detected speech of the patient, and, in response to the signal, reducing the treatment pressure applied to the patient.

  • Patent number: 10398863
    Abstract: A method of using CPAP equipment to sense cardiogenic oscillations in a patient's airflow, and to monitor and treat the patient's cardiac condition. The apparatus diagnoses cardiac morbidity conditions, such as the existence of arrhythmias or other cardiac abnormalities, and influences and optimizes cardiac stroke volume. The apparatus further monitors pulse-transit time, changes in the heart pre-ejection period, and the duration of the cardiac cycle.
