LOW COST CPAP FLOW GENERATOR AND HUMIDIFIER ASSEMBLY

摘要

A CPAP device wherein humidification detection and/or control is performed by a microprocessor of the CPAP device without requiring a separate humidification control chip. The microprocessor (150) may also control the flow generator motor (140) and the flow generator display (145). Further, the microprocessor may include code to prevent "brown-out", and/or to detect the availability (connection and/or operability) of the humidifier. Humidifier detection may be carried out using power consumption or temperature sensor signal analysis, e.g., facilitated by use of a pull-up resistor.
