DEVICE: AirLife (10885403039492)

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.

A length of tube made of durable materials (e.g., rubber, silicone) intended to be used to conduct breathing gases towards or away from a patient during the respiratory cycle, typically during anaesthesia or ventilation [including continuous or bi-level positive airway pressure ventilation (CPAP or BPAP)]. It is intended to function as part of a breathing circuit and with other separate gas delivery devices (e.g., respiratory mask, connectors). This is a reusable device intended to be cleaned/disinfected prior to use.

A mechanical device designed to provide a visual indication of a patient's airway pressure during ventilation. It is typically contained in a clear housing marked with a pressure scale [e.g., 5 to 60 cm H20 (hPa)], and has a spring-loaded indicator that, in resistance to the expiratory flow of air, registers the airway pressure. It connects to the manometer port of a variety of ventilation devices such as a resuscitation bag, hyperinflation bag, continuous positive airway pressure (CPAP) mask, or a CPAP circuit. It may be used in a healthcare setting (including ambulatory) or in the home. This is a single-use 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.
