17. 4 Device Classification The AB800 gt Absorber is classified as follows e Type CF applied part 1 5 Background The forms the gas supply end of a circle rebreathing circuit for the purposes of anaesthetic gas delivery It provides the one way valves which form the expiratory and inspiratory limbs of the circuit It allows a means of introducing fresh gas to the circuit via the inspiratory limb and provides means for controlled flow through a soda lime absorber canister on the expiratory limb of the circuit for the removal of CO2 The system can be used with high flow low flow or minimal flow of fresh gas for patient ventilation In addition positive pressure ventilation may be delivered by means of a manual bag or a bellows system driven by an anaesthetic ventilator the ventilator is not part of the AB800 A manual switch controlled by the user determines which of these positive pressure sources is connected to the circle system The switch is normally at the bag position for manual ventilation of the patient and is switched to the ventilator position when automatic ventilation is required The AB800 Absorber forms part of a semi closed patient breathing system which employs a circle absorber for the elimination of The system can be used with high flow low flow or minimal flow of fresh gas for patient ventilation The circle absorber section of the AB800 consists of a canister for the soda lime absorbent and
