CONNECTING TO A CYLINDER
An oxygen regulator is required to connect the ventilator to an oxygen cylinder. Ensure that the oxygen regulator
meets the requirements below and is appropriate for the cylinder being used.
REGULATOR REQUIREMENTS
Pressure output
41-87 PSI (50 PSI nominal)
Pressure flow
≥ 40 LPM at ≥ 41 PSI
Pressure fitting
DISS 1240
Flow fitting*
¼" Barb connector
Minimum required selectable flow*
0, 4 (L/min)
* Required for purging only. For more information, see "Purging the Breathe Universal Circuit™ Connector and
Breathe Pillows Interface™" on page 113.
WARNING:
• If the ventilator is not used with a regulator capable of 41 PSI to 87 PSI (nominal 50 PSI) with greater than
40 LPM capability, patients may not receive appropriate respiratory therapy.
• Use the ventilation system with only approved medical compressed oxygen. Use with non-approved
sources of oxygen may cause the ventilation system to malfunction and the patient may not receive
appropriate respiratory therapy.
• Use only a Breathe Technologies® source gas supply hose with the ventilation system. If an unauthorized
source gas supply hose is used with the ventilation system, the system may be damaged.
• Do not use the Breathe Technologies® Life2000® Ventilation System with oxygen in the presence of
flammable anesthetics such as fluroxene, cyclopropane, divinyl ether, ethyl chloride, ethyl ether, and
ethylene, as they may form flammable or explosive mixtures with oxygen.
• Before beginning ventilation therapy, verify that there is an adequate supply of oxygen for the intended
duration of the therapy. Otherwise, the patient may not receive appropriate therapy.
• Do not allow smoking near oxygen sources or near the ventilation system and do not place oxygen
sources or the ventilation system near any source of direct heat or open flame because flammable
materials burn more readily in the presence of oxygen.
• Do not use the ventilator in the presence of flammable anesthetics.
• The interface, source gas supply hose, and power cords should be positioned to avoid restricting
movement, causing a tripping hazard, or posing a strangulation risk.
TIPS:
• If using a cylinder, make sure your oxygen supply is sufficient for your length of use. For more information
about estimating oxygen usage, see "Cylinder Duration Information" on page 150.
• If not connected to AC power, make sure the ventilator battery has sufficient charge for your length of use.
• Refer to the regulator and source gas supply manufacturers’ instructions for more information.
• During use in Stand-Alone Configuration, the oxygen hose should remain connected to the ventilator
at all times, except when required to be disconnected for maintenance, testing, or replacement. If it is
disconnected while the ventilator is on and delivering therapy, a Low Gas Pressure alarm will occur. For
more information see"Low Gas Pressure" on page 97.
• The Life2000® Ventilator can work using most common medical grade oxygen cylinders when using
the appropriately-rated regulator. Ensure the appropriate regulator for the cylinder is being used before
connecting to the ventilator. Information about the oxygen cylinder and its specific regulator requirements
may be found by contacting the oxygen cylinder supplier.
