Alarms Lack or low oxygen pressure with consequent cut-off of nitrous oxide delivery
Safety devices AGAINST THE ADMINISTRATION OF HYPOXIC MIXTURES MIX-LIFE: it
always guarantees a minimum concentration of 25 % oxygen on mixtures which
includes nitrous oxide.
IN CASE OF LACK OR LOW OXYGEN PRESSURE CUT-OFF: audible alarm
with immediate cut-off of nitrous oxide delivery.
AGAINST OVERPRESSURE IN FLOWMETER BOX : safety valve calibrated at
0.8 bar for the protection of the glass rotameters.
IN CASE OF LACK OR COMPRESSED AIR LOW PRESSURE : all the devices
(gas feeding) supplied by compressed air are automatically supplied by oxygen.
AGAINST THE SIMULTANEOUS DELIVERY OF AIR AND N

O : selection by
membrane key on the flowmeter front panel.
Control for activation of
exit of fresh gas for
manual ventilations.
Setting of MANUAL modality on ventilator (MAN) with automatic deviation of
fresh gas to the manual system of anaesthesia unit valves group, or to a TO-
AND-FRO circuit with visual indicator.
