DEVICE: Heated Circuit (00709078001086)

An assembly of devices designed to conduct medical gases from an anaesthesia unit/workstation to a patient artificial airway/anaesthesia mask (not included) during general anaesthesia. It includes breathing tubes and a Y-piece connector, typically with a ventilator/ventilation bag and appropriate connectors, and may include a carbon dioxide (CO2) absorber, a one-way directional valve, or adjustable pressure limiting (APL) valve. This is a single-use device.

A non-sterile device intended to be integrated within a ventilator breathing circuit and used in conjunction with a heated respiratory humidifier (from which it draws its power) to maintain the temperature of inspiratory gasses during ventilation of an infant/neonate. It typically consists of a compact heating unit which and a length of heated wire which is integrated within the lumen of a neonatal/paediatric breathing circuit tube. This is a reusable 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.
