Publication number: 20220008681Abstract: Some embodiments provide for humidifier control systems and methods configured to adjust power to a heater plate in a surgical humidifier to account for changes in flow rate to provide a consistent output, to provide functionality for different modes of use, and to provide accurate control over temperature and/or humidity at relatively low flows. The humidifier control system can receive a flow rate reading and determine a power requirement corresponding to the received flow rate reading, wherein the power requirement is one of a plurality of set points which correspond to ranges of flow rates. The humidifier control system can determine a mode of use based at least in part on the flow rate reading. The humidifier control system can provide electrical power to the heater plate according to the power requirement and/or the mode of use.Type: ApplicationFiled: September 23, 2021Publication date: January 13, 2022Inventors: Ali Ghalib Abdul Rahman Ghalib, Lina Tessy, Joseph Patrick Walter Strevens, Paul David Phillips
