초록 ▼

A device provides respiratory treatment such as for sleep disordered breathing and other respiratory conditions in a discreet configuration to provide a minimally invasive system. The system may include a flow pressurizer apparatus configured to generate a pressurized flow of air through a small bore delivery conduit toward a patient interface. The system may further include a treatment compensator coupled with the fine bore delivery conduit. The treatment compensator may be configured at the patient interface to reduce pressure for patient inspiration. A processor may control adjustments to the pressure generated by the flow pressurizer apparatus.
