Flexicare-Mapleson A (Parallel Lack System)

Product Details :

The Mapleson A is inefficient during controlled ventilation. Venting the gas in the circuit occurs during the inspiratory phase, and the alveolar gases are retained in the tubing during the expiration phase. Hence, alveolar gas is rebreathed before the the pressure in the system increases sufficiently to force the expiratory valve open.
