Abstract
Apparatus for humidifying a flow of air to be delivered to a patient, the apparatus including an inlet (5118) to receive the flow of air, an outlet (5122) to emit a humidified flow of air, a humidifier reservoir (5110) configured to contain a body of water for humidifying the flow of air, the humidifier reservoir being in fluid communication with the inlet and outlet, at least one sensor (e.g. vibration sensor 5234) configured to generate a signal indicative of a physical characteristic associated with the quantity of the body of water in the humidifier reservoir, and a controller configured to provide an indication of the quantity of the body of water in the humidifier reservoir, based on the signal. The physical characteristic is selected from the group consisting of: a vibration characteristic of the humidifier reservoir or the apparatus, an electrical characteristic of the body of water, a weight characteristic of the body of water, and a characteristic of response of the body of water to a force imparted to the body of water.
