ABSTRACT:
A warning and protection device particularly suitable for use in gas anaesthetizing systems is provided, the device having means communicable with each of two gases used in the anaesthetizing process. The means communicable with one of the gas sources includes a pressure sensitive component which in turn is associated with a valve in the second gas means, the construction and arrangement being such that when a drop in gas pressure within the first gas means is sensed below a predetermined value the gas flow through the second gas means is blocked off.
