Warnings and Precautions
These warnings and precautions are to help you to understand how to safely operate a 2-Cylinder
Mobile Cart with a nitrous oxide & oxygen delivery System. A WARNING alerts you to a possible
hazard to people. A CAUTION alerts you to the possibility of equipment damage.
WARNING: Protect against crossed lines at the 2 Cylinder Mobile Cart regulator assembly. Verify
gas indexing pin locations, color coding of gauges, seal washer, & orientation of
regulator assembly. Follow instructions in Regulator Check page 6.
WARNING: New or modified installations
– properly connected gas pipelines (external gas supply)
are absolutely essential to patient safety. The ultimate responsibility of assuring that
lines are not crossed rests with the user.
WARNING: Do not allow crossed lines to defeat the safety features
of the Mobile
Cart, with any external gas supply, and/or central gas supply manifold systems. Crossed
lines will create a dangerous and hazardous condition where, under a loss of oxygen
supply, 100% nitrous oxide will be delivered through the oxygen delivery path and
subsequently to the patient.
Use patient observation to prevent over sedation. If a patient becomes over sedated when
being delivered 100% oxygen [during an apparent loss of nitrous oxide supply], it is a
definite indication of crossed lines. If crossed lines are suspected, remove the mask
immediately and encourage mouth breathing. Deliver pure oxygen from an oxygen
demand valve only if the oxygen source is independent from the suspected crossed lines
area.
WARNING:
Porter Instrument equipment utilizes the
cross+protection
system. The flexible hose and
connectors that connect to the Regulator Assembly and the Flowmeter or Nitronox inputs are
diameter indexed; 3/8” O.D. for Nitrous Oxide and ½” O.D. for Oxygen. The
cross+protection
system is designed to prevent misconnection of Oxygen and Nitrous Oxide hoses.
DO NOT
ATTEMPT TO CHANGE THE DIAMETERS OR CONNECTORS OF THE REGULATOR
ASSEMBLY!
Tampering with the
cross+protection
system constitutes acceptance of liability
by the installer.
WARNING:
The Mobile Cart within a nitrous oxide & oxygen delivery system, with Flowmeter or Nitronox,
is intended to be used by medical personnel trained in the device use and the use of nitrous
oxide and oxygen for medical applications. Do not use for other intended uses. Use approved
Porter Flowmeter or Nitronox.
WARNING:
Do not use the Flowmeter or Nitronox device for the administration of general anesthesia or as
a part of, or in conjunction with, a general anesthesia administration system.
WARNING:
Inspect and maintain the analgesia delivery system to prevent N2O leaks in all hoses,
connections and fittings. This includes the delivery system (Mobile Cart is mounting accessory)
and the hoses and connections to the Regulator Assembly. Have all leaks repaired
immediately.
WARNING:
Use Scavenging: Medical workers are exposed to N
2
O during administration of N
2
O/O
2.
Controls are effective in the patient treatment area to achieve low levels of ppm (parts per
million) exposure. Controls include System Maintenance, Ventilation and Work Practices.
Your accessory Scavenger System is an important part of the system of controls in medical
settings.
