This system consists of a reservoir bag close to the fresh gas outlet with the APL valve placed at the patient end (Magill A, or expiratory limb-Parallel Lack). During the expiratory phase, exhaled gases will force the fresh gas back into the circuit and reservoir bag, and escape through the APL valve (scavenging port). The system requires a low flow (0.8-1 times of Minute Volume, approximately 6-8 litres/minute) during spontaneous respiration to prevent rebreathing. This system is not recommended for intermittent positive pressure ventilation (IPPV).

All Mapleson circuits are supplied with our new APL Valve
