A system is provided for delivering gas to a patient during a medical procedure. The system comprises a heater arranged to heat at least one of the gas and a humidification liquid. The system comprises a controller arranged to control the system according to a first mode during delivery of a first flow rate of gas and a second mode during delivery of a second flow rate of gas. The controller monitors an electrical characteristic of the heater to select the mode of operation and/or to determine an operating state of the system.

Methods and systems for delivering gas to a patient

An active smoke filtration unit is used to remove smoke during laparoscopic surgery. The active smoke filtration unit is part of a recirculation circuit. The recirculation circuit is pneumatically isolated from a primary flow generator, such as an insufflator, by a valve assembly. The active smoke filtration unit can be housed separately from the valve assembly or together with the valve assembly. The recirculation circuit can include a humidifier to heat and humidify the insufflation gases.
