DEVICE: AirLife (10885403039683)

A device designed to prevent the drying of airway passages associated with the inhalation of oxygen (O2) by adding water vapour to the dry gas as it is passed through, or more seldom, over water. It typically consists of a graduated container (reservoir) for the water, a top piece that functions as a detachable lid (typically a screw lid with a gastight seal), and a tube that protrudes into the water to divert the gas below the water level. This device, commonly known as a bubble humidifier, does not heat the water. It has connectors: 1) one (e.g., a winged nut) that connects to an oxygen therapy flowmeter; and 2) one to which the patient tubing is connected. This is a reusable device.

An assembly of devices designed to conduct air or oxygen (O2) enriched gases and additional gases [e.g., nitrous oxide (N2O), halogenated gases] from a ventilator to a patient artificial airway/respiratory mask (not included). It includes breathing tubes, a Y-piece connector, and provides connections for devices that humidify, deliver medication, and monitor gas concentration or pressure within the breathing circuit; some types may include a carbon dioxide cuvette and/or an integrated heating wire powered by a connected humidifier intended to warm breathing gases as they enter the patient's airway. This is a single-use device.

A device intended to be placed within a breathing circuit proximal to the patient, to remove and retain microbes whilst capturing the patient's exhaled heat and moisture so that they can be used to heat and humidify the therapeutic gases inspired by the patient. It is typically a plastic housing which contains both a bidirectional microbial filter, intended to reduce the risk of cross-contamination between patients, and a heat/moisture exchanger (HME), intended to maintain the mucous membranes of the respiratory tract. It is typically used during anaesthesia or periods of prolonged respiratory support/therapy. This is a single-use device.

A connecting device, usually with a small channel or tubing, intended to join a water/saline pack or a noninvasive ventilation respiratory unit to an inhalation therapy device (e.g., humidifier, vibrating mesh nebulizer, oxygen therapy delivery system). It may be used when the connection is compatible (e.g., when the connected devices are of the same manufacture) or when incompatible (e.g., different manufacture). This is a single-use device.
