Systems and methods to provide respiratory therapy may determine a target pressure level in a current therapy session on the successful completion and/or compliance of a patient (for example for at least a threshold amount of respiratory therapy) during one or more prior therapy sessions. By gradually increasing the provided pressure level, patients may improve compliance, comfort, and/or other indicators of how well-tolerated the respiratory therapy is for a patient.

1. A system for providing respiratory therapy to a subject having an airway, the system comprising: a pressure generator configured to generate a pressurized flow of breathable gas for delivery to the airway of the subject;one or more sensors configured to generated output signals conveying information related to one or more gas parameters of the pressurized flow of breathable gas;one or more processors configured to execute processing modules, the processing modules comprising:a compliance module configured to determine an amount of respiratory therapy that the subject received during a first therapy session, wherein the compliance module is further configured to determine whether the amount meets and/or passes a threshold amount of respiratory therapy;a target module configured to determine a target pressure for the pressurized flow of breathable gas during therapy sessions based on a prescribed therapy regimen and determinations by the compliance module pertaining to prior therapy sessions such that, for a second therapy session subsequent to the first therapy session, the target module determines the target pressure for the pressurized flow of breathable gas based on one or more determinations, by the compliance module pertaining to the first therapy session;a control module configured to adjust levels of one or more gas parameters of the pressurized flow of breathable gas based on the determined target pressure; anda randomness module configured to determine a measure of randomness in a breathing pattern of the subject during the first therapy session based on analysis of durations of inhalations during the first therapy session,wherein determinations by the compliance module are based on the measure of randomness determined by the randomness module, wherein (i) responsive to a first determination that the measure of randomness is below a first threshold of randomness, the target module is configured to increase the target pressure and/or the compliance module is configured to decrease the threshold amount of respiratory therapy and (ii) responsive to a second determination that the measure of randomness is above a second threshold of randomness, the target module is configured to decrease the target pressure and/or the compliance module is configured to increase the threshold amount of respiratory therapy. 2. The system of claim 1, wherein determinations by the compliance module are based on comparisons between measures of randomness determined during multiple therapy sessions. 3. The system of claim 1, further comprising: a sleep detection module configured to detect sleep onset, wherein determinations of the target pressure by the target module are further based on whether sleep onset has been detected. 4. The system of claim 1, further comprising: a swallow detection module configured to detect swallowing by the subject, wherein the target module is further configured to temporarily reduce the target pressure to reduce aerophagia. 5. A method for compliance determination regarding respiratory therapy of a subject having an airway, the method comprising: generating output signals conveying information related to one or more gas parameters of a pressurized flow of breathable gas that is delivered to the airway of the subject;determining an amount of respiratory therapy that the subject received during a first therapy session;determining a compliance determination, wherein the compliance determination is based on whether the amount meets and/or passes a threshold amount of respiratory therapy;determining a target pressure for the pressurized flow of breathable gas during a second therapy session subsequent to the first therapy session, wherein the target pressure is based on a prescribed therapy regimen and the compliance determination pertaining to the first therapy session;determining a measure of randomness in a breathing pattern of the subject during the first therapy session based on analysis of durations of inhalations, wherein the compliance determination is based on the measure of randomness,increasing the target pressure and/or decreasing the threshold amount of respiratory therapy, responsive to determining that the measure of randomness is below a first threshold of randomness; anddecreasing the target pressure and/or increasing the threshold amount of respiratory therapy, responsive to determining the measure of randomness is above a second threshold of randomness. 6. The method of claim 5, wherein the compliance determination is further based on a comparison between measures of randomness determined during multiple therapy sessions. 7. The method of claim 5, further comprising: detecting sleep onset, wherein determination of the target pressure is further based on whether sleep onset has been detected. 8. The method of claim 5, further comprising: detecting swallowing by the subject, wherein the target pressure is temporarily reduced to reduce aerophagia. 9. A system configured for providing respiratory therapy to a subject having an airway, the system comprising: means for generating a pressurized flow of breathable gas for delivery to the airway of the subject;means for generating output signals conveying information related to one or more gas parameters of the pressurized flow of breathable gas;means for determining an amount of respiratory therapy that the subject received during a first therapy session;means for determining a compliance determination, wherein the compliance determination is based on whether the amount meets and/or passes a threshold amount of respiratory therapy;means for determining a target pressure for the pressurized flow of breathable gas during a second therapy session subsequent to the first therapy session, wherein the target pressure is based on a prescribed therapy regimen and the compliance determination pertaining to the first therapy session;means for adjusting levels of one or more gas parameters of the pressurized flow of breathable gas based on the determined target pressure;means for determining a measure of randomness in a breathing pattern of the subject during the first therapy session based on analysis of durations of inhalations,means for, responsive to determining the measure of randomness is below a first threshold of randomness, increasing the target pressure and/or decreasing the threshold amount of respiratory therapy, andmeans for, responsive to determining the measure of randomness is above a second threshold of randomness, decreasing the target pressure and/or increasing the threshold amount of respiratory therapy. 10. The system of claim 9, wherein the compliance determination is further based on a comparison between measures of randomness determined during multiple therapy sessions. 11. The system of claim 9, further comprising: means for detecting sleep onset, wherein determination of the target pressure is further based on whether sleep onset has been detected. 12. The system of claim 9, further comprising: means for detecting swallowing by the subject, wherein the means for determining a target pressure for the pressurized flow of breathable gas is further configured to temporarily reduce the target pressure to reduce aerophagia.
