Abstract: Sleep apnea can be treated with pressure support therapy using a target pressure level. Detected respiratory events during consecutive multi-session testing period are compared to determine statistical metrics covering gradual changes in therapy efficiency. Adjustments to the target pressure level are based on changes in variability, and maybe made in between therapy sessions.

Abstract: Systems and methods for providing respiratory therapy to a subject respond and/or adapt to the detection of an occurrence of a respiratory event. For example, the pressure level of a pressurized flow of breathable gas may be increased responsive to the occurrence of one or more apneas. Based on usage information spanning more than one therapy session, such as the tracked pressure levels, a starting pressure level for a pressurized flow of breathable gas for a subsequent therapy session is determined. The starting level at the beginning of the subsequent therapy session(s) may be the 90% pressure level as determined during the preceding period during which usage information has been gathered.

Abstract: A method of detecting dyssynchrony between a patient and a pressure support system includes receiving patient flow data relating to a flow of gas provided to the patient by the pressure support system, receiving an I/E state signal representing a respiratory phase of the patient as determined by the pressure support system, and analyzing the patient flow data and the I/E state signal and declaring a dyssynchrony for a breath based on at least one of the patient flow data and the I/E state signal. The method includes determining whether at least one of a number of predetermined criterion is satisfied based on at least one of the patient flow data and the I/E state signal, and declaring the dyssynchrony for the breath if it is determined that at least one of the number of predetermined criterion is satisfied.

Abstract: A monitoring system is used to measure various parameters of the sleep, respiration, and/or other bodily functions of a subject. One or more metrics are calculated that quantify deviation from the mean, trends, changes over time, and/or other changes in the parameters. The metrics are used to generate notifications of these changes that can be conveyed to caregivers and/or other users.

Abstract: A pressure support methodology and system that utilizes at least two, and possibly all three, of information relating to (i) airway patency, i.e., the degree to which the patient's airway is open, (ii) the primary cause of the current sleep disordered breathing event, and (iii) the patient's response to previous pressure changes to automatically titrate pressure when presented with a sleep disordered breathing event. In another embodiment, pressure may be automatically titrated based solely on the primary cause of the sleep disordered breathing event.

Abstract: A method of operating a ventilator or pressure support system that automatically determines a timed back up rate for the patient based on the patient's spontaneous breathing patterns. The aggressiveness of the determined rate increases as the patient takes less spontaneous breaths. Also, a method wherein one or more mechanisms are used to determine whether a machine breath should be issued. Each mechanism consists of a basic timing element coupled with one or more logical permits. Both the timing element and each of the one or more logical permits must be satisfied to allow the timing mechanism to trigger a machine breath.
