Abstract:
1. A breathing device for optimizing the positive airway pressure to a patient, the device comprising: a gas source to apply a positive pressure to the airway of a patient, said gas applied via a mask or nose fitting having an inlet adapted for coupling with the gas source; a sensor configured to sense an inspiratory flow of breathing gas to the patient and to output signals relative to an inspiratory waveform of the patient; a microprocessor in communication with the sensor sensing inspiratory flow of breathing gas to the patient, to receive signals relating to an inspiratory waveform, analyze the received signals, and generate control signals based at least upon the analysis of the received signals, wherein analyzing the received signals includes correlating data values associated with the received signals to a pure sine wave; and a controller coupled to the breathing gas source and associated with the microprocessor, wherein the controller is configured to adjust the positive pressure in response to control signals received from the microprocessor.
