BREATHING GAS HUMIDIFIER

A breathing gas humidifier includes a water chamber, which has a first area for receiving water and a second area for receiving breathing gas. An inlet supplies breathing gas to the breathing gas humidifier, an outlet discharges conditioned breathing gas from the breathing gas humidifier, and a bubbler, including a bubbler element, has outlet ports. The breathing gas humidifier is configured to provide, in a first configuration, a fluidic connection between the inlet and the first area via the bubbler element to pass the breathing gas through the water to obtain the conditioned breathing gas. The breathing gas humidifier is further configured, in a second configuration, to provide a fluidic connection between the inlet and the second area to direct the breathing gas along a water surface to obtain the conditioned breathing gas. The breathing gas humidifier is selectively switchable between the first configuration and the second configuration.
