2.2 OPERATING INSTRUCTIONS
1.
Ensure that the Equinox® II Demand Valve/Regulator connection
is secured and no leaks present.
2.
Turn the cylinder hand wheel counter clockwise to the ON
position. Ensure that the regulator contents gauge reads at least
500 psi. If not, replace with a full cylinder.
3.
If used, connect the bacterial filter between the Equinox® II
Demand Valve and the Universal Facemask.
4.
Instruct the patient in its operation. Most protocols require
the gas mixture be self-administered by the patient to prevent
inadvertent excessive administration by an attendant.
5.
To trigger the demand valve and obtain an adequate flow of
gas, it is necessary to make a good mask to face seal. Simply place
the mask on the patient's face, covering both the nose and mouth.
Instruct the patient to hold the mask on his/her face with a light
pressure and breathe normally. The sound of gas flowing should
be heard with each inspiration. If not, adjust the patient's hold
on the mask for a better seal and ask the patient to breath more
deeply.
6.
Continue administration as per local management protocol and
scavenge waste gas as per 2.3 if required.
7.
Turn OFF the cylinder after each use and release remaining gas
from the system by placing the bleed pin attached to the regulator
into the center hole on top of the Demand Valve and depress until
gas flow ceases.
NOTE: The use of a patient circuit or bacterial/viral filter with the
Equinox® II demand valve may increase the patient's inspiratory
work of breathing.
