FLOW METERING DEVICE AND FLOW OUTLET
GCE regulators can be supplied with a fl ow-metering device - fl ow control
head "C". This function is used to supply a gas fl ow (l/min) at atmospheric
pressure directly to the patient through the fl ow outlet "E", e.g. through a
cannula or a facemask.
The fl ow outlet "E" can be hose nipple (for cannula or mask) or outlet with
thread (for humidifi er).
F PRESSURE OUTLET
The regulator may be fi tted with a pressure outlet. The pressure outlet is
the outlet directly from the low-pressure chamber. Two types of the pres-
