2. OPERATING PROCEDURE
2.1 DEMAND BREATHING
The O-Two Equinox® II Demand Valve is designed to operate on
compressed Nitrous Oxide/ Oxygen gas. It is intended to provide
50/50% Nitrous Oxide/Oxygen mixture to the patient at a safe
delivery pressure and adequate flow rate upon demand.
An inspiratory effort by the patient will activate the demand valve
and Nitrous Oxide/ Oxygen will flow to the patient at a rate and
volume in line with their inspiratory effort.
