Principles Of Operation 3
The Infant and Child models of the MR‐100™ Plus Manual Resuscitator are
fitted with pressure relief valves (see figure 4). These valves open when the
pressure is in excess of 40±5cmH

Figure 4. Pressure Relieve Valve.
Should higher inspiratory pressure be required, the pressure relief valve
may be overridden by placing thumb over the valve as shown in figure 5. It
Is also possible to lock the pressure relief valve in this position with Lock
type Non rebreathing Valve. Just twist the valve half a turn and it will stay
in the overridden position. (Lock Arrow forward to the NRV direction as
Figure 5.1).
