Adult breathing circuit Mapleson A

Mapleson

A comprehensive range of semi-open anaesthesia circuits are available, to suit your clinical needs. All systems are supplied with one spare 22mm male connector to accommodate most connection configurations. Mapleson A has a reservoir bag close to the fresh gas inlet with the APL valve placed at the patient end. During the expiratory phase, exhaled gases force the fresh gas back into the circuit and reservoir bag, escaping through the APL valve.
