Abstract

A system including methods and apparatus for treatment of a medical disorder such as obstructive sleep apnea or congestive heart failure. The system involves applying a gain to flow rate of pressurized gas delivered to a patient during inspiratory and/or expiratory phases of a respiratory cycle to deliver the pressurized gas in proportion to the respective gains during inspiration and/or expiration. A base pressure may be applied in addition to the gain-modified pressures and an elevated pressure profile may be employed to assist or control inspiration. The system may be utilized in connection with conventional continuous positive airway pressure treatments, such as CPAP
or bi-level positive airway pressure equipment to effect various beneficial treatment applications.

Claims (10)

1. An apparatus for delivering pressurized breathing gas to an airway of a patient, that includes: a gas flow generator, a patient interface coupled to the gas flow generator to communicate a flow of breathing gas from the gas flow generator with an airway of a patient, a sensor associated with the gas flow generator or the patient interface that detects a fluid characteristic associated with the flow of breathing gas within the patient interface and outputs a signal corresponding to the fluid characteristic, a pressure controller associated with the gas flow generator or the patient interface to control a pressure of the flow of breathing gas delivered to a patient, an input device, and a processing means, adapted to receive the signal output from the sensor, and a continuous positive airway pressure (CPAP) and an expiratory gain Gain Exp from the input device, characterized in that:
the processing means determinines a pressure to be delivered to a patient during inhalation (Pinhalation) as:
Pinhalation = CPAP, and determining a pressure to be delivered to such a patient during exhalation (Pexhalation) as:
Pexhalation = CPAP + Gain Exp * (Flow - FlowOffset), where "Flow" is the current patient flow measured by the sensor, where "FlowOffset"
corresponds to a final value of patient flow during inspiration responsive to the final value being positive, otherwise FlowOffest is set to zero, and wherein the processing means controls the pressure controller so as to deliver a pressure corresponding to Pinhalation during an inspiratory phase of a breathing cycle and corresponding to Pexhalation during an expiatory phase of a breathing cycle.
2. The apparatus of claim 1, wherein the patient interface includes a conduit, and wherein the pressure controller is a valve associated with the conduit that exhausts gas from the conduit to control the pressure of the flow of breathing gas delivered to such a patient.
3. The apparatus of claim 1, wherein the CPAP level is set via the input device.
4. The apparatus of claim 1, wherein the CPAP level is determined by the processing means based on an output of the sensor.
5. The apparatus of claim 1, wherein the processing means controls the pressure controller so as to prevent pressure oscillations during expiration.
6. The apparatus of claim 5, wherein the processing means controls the pressure controller to prevent oscillations by causing the pressure controller to provide a pressure to a patient during expiration after a maximum pressure reduction has been met at a greater of (1) Pexhalation and (2) a current pressure being provided to such a patient.
7. The apparatus of claim 1, wherein the processing means also limits a rate of change for the pressure of the flow of breathing gas to be delivered to such a patient.
8. The apparatus of claim 7, wherein the processing means sets a first rate of change limit for an increase in the pressure to be delivered to a patient and sets second rate of change limit for a decrease in the pressure to be delivered to a patient.
9. The apparatus of claim 1, further comprising means for smoothing transitions between changes in a pressure of the flow of breathing gas to be delivered to a patient.
10. The apparatus of claim 9, wherein the means for smoothing comprises a filter for filtering a signal provided by the processing means to the pressure controller, wherein the signal corresponds to Pexhalation or Pinhalation determined by the processing means.
