Equinox® II Administration System manual
1. INTRODUCTION
1.1 Equinox® II ADMINISTRATION SYSTEM
TheEquinox®II AdministrationSystemis intendedforadministration
of 50%/50% N2O/O2analgesic gas mixture and is specifically
designed for use in emergency and obstetric analgesia.
The Equinox® II Administration System consists of a demand valve,
a single stage pressure regulator, a supply hose and a universal
patient face mask. It can be operated anywhere 50% Nitrous
Oxide/50% Oxygen mixture cylinders are available.
The Equinox® II Demand Valve is lightweight, portable, and
extremely durable and is intended to administer 50%/50% N2O/
O2analgesic gas on patient’s demand.
The pressure regulator is intended to lower the high, variable
cylinder pressure to a lower constant working pressure for the
Demand Valve.
Note: Only those individuals trained in the administration of
Nitrous Oxide/Oxygen mixtures should use this equipment.
Thoroughly review the instruction manual before use.

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 eort 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 eort.

6Equinox® II Administration System manual
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.

Equinox® II Administration System manual
2.3 SCAVENGING OF WASTE EXHALED GAS
To scavenge exhaled air from the patient during inhalation
analgesia a scavenging system must be employed. There are two
options for exhaled gas scavenging:
[1] Scavenger Adapter
The optional Patient Valve with Scavenger Adapter (17MP1100-
90DEG) is designed for exhaled gas scavenging.
To apply,
• Remove the Non-rebreathing Patient Valve from the demand
valve;
• Attach the Patient Valve with Scavenger Adapter on to the
demand valve;
• Connect a scavenging tube to the 19mm/30mm outlet of the
Scavenger Adapter to divert the exhaled gas to the exhaust
system.
NOTE: The 30 mm exhalation port meets the requirements of the
International Standards for Conical Connectors for Low Pressure
Medical Gas Systems and will allow the attachment of corrugated
tubing so that the patient’s exhaled breath can be scavenged
from the exhalation valve to the exhaust method chosen by the
facility using the device.
[2] Analgesic Gas Patient Circuit
The optional Analgesic Gas Patient Circuit (01CV8028) can be
connected to the Equinox® II demand valve with its expiratory
tube attached to the exhaust system.
To apply,
• Remove the Non-rebreathing Patient Valve and the Diaphragm
(17MP1528) from the demand valve;
• Screw the 15/22mm housing adapter (provided with 01CV8028)
on to the demand valve. Attach the white inspiratory tube of
01CV8028 to the housing adapter;
• Attach the pink expiratory tube of 01CV8028 to the exhaust
system.

3. SERVICING
3.1 ROUTINE MAINTENANCE
WARNING
The Equinox® II Administration System is designed to provide
years of reliable service in all emergency situations. Failure
to follow the maintenance and inspection routines properly
could result in incorrect operation of the demand valve.
To ensure proper operation of the Equinox® II Administration
System, regular inspection and checking of the demand valve
and accessories for correct function should be undertaken by a
responsible member of sta on a regular basis.
This check is to ensure that all of the accessories and demand
valve components are present, the gas mixture cylinder is full and
that the demand valve is in working order.
MAINTENANCE
Function parameters should be checked at least every six months,
and more frequently in high use applications. Units with test
pressures outside of the ranges listed in the product specifications
should not be used. O-Two Medical products are not designed for
field disassembly or service outside that indicated in this manual.
Any malfunctioning units should be returned to the manufacturer or
an Authorized O-Two Medical Technologies Dealer. Unauthorized
repairs will nullify the product warranty.

3.2 CLEANING AND DISINFECTION
Routine cleaning and/or disinfection of the Equinox® II
Administration System should be undertaken after each patient
use as follows to maintain the equipment in a clean condition.
NOTE: The use of a patient circuit or a bacterial/viral filter with
the Equinox® II demand valve isolates the patient’s exhaled breath
from the demand valve internal pathways. Therefore, the need for
the cleaning and disinfection, after each patient use, of the Non-
rebreathing Patient Valve (A & C) and Diaphragm (B), attached to
the demand valve, is negated.
It is however recommended that the demand valve is cleaned and
disinfected externally using a hard surface disinfectant suitable
for use with the materials of manufacture.

Ensure that the cylinder is turned o (completely clockwise)
and bleed any remaining gas out of the gas supply hose.
1. Remove the facemask, the patient circuit and the bacterial filter
(if applicable) from the Equinox® II Demand Valve. Discard the
bacterial filter and the patient circuit.
2. Disconnect the demand valve from the regulator. The regulator
can be cleaned with a clean soft cloth.
3. Unscrew patient valve (A) from the unit body (D) being careful
to ensure that the diaphragm (B) is retained.
4. Remove the diaphragm and anti-entrainment ring (C) from the
patient valve housing and wash these components thoroughly in
a mild soap solution;
5. Disinfect the face mask, patient valve and diaphragm using
commonly available cold chemical disinfecting solutions. Rinse
thoroughly with water after disinfection.
6. Sterilization, if required, may be achieved by other methods
compatible with the materials of manufacture of these components
including Ethylene Oxide Gas and Cidex.
7. The demand valve body (D) and gas supply hose can be
wiped over with a soft cloth and mild soap solution and may be
disinfected using a hard surface disinfectant that is compatible
with aluminium.
8. Dry all components thoroughly.
9. Re-assemble and check performance.
WARNING
Do not immerse the demand valve unit or the pressure
regulator into cleaning solution or disinfectant.
Discontinue use and discard the face mask, the patient
valve and the diaphragm should discoloration or
deterioration be observed.
