ABSTRACT:
The breathing apparatus disclosed includes a first connector structure which provides ports for connection to a supply of fresh breathing gases, to an afferent gas tube and to an afferent gas bag. The first connector structure also provides a port to which a ventilator can be connected, a port to which an efferent gas tube can be connected, and a connection to an efferent gas bag. The afferent gas tube is of larger diameter than the efferent gas tube. The apparatus further includes a second connector construction to which said tubes are connected and which has a port for connection to the patient. The second connector structure causes preferential flow between the patient port and the afferent gas tube port.
