WARNING: NEW OR MODIFIED INSTALLATIONS
ALWAYS ASSURE THAT LINES ARE NOT CROSSED!
WARNING: External Source Connections: New or modified central supply installations - properly
connected gas pipelines leading to any external supply of the E-Stand are absolutely essential to
patient safety. The authorized distributor or contractor should provide written documentation that all gas
pipelines are connected properly and that the system has been pressure tested prior to use. While this is
a good business practice, it is important that the user verify by their own test, independent of the
authorized distributor or contractor, that all gas pipelines are connected correctly prior to using the
system. The ultimate responsibility of assuring that lines are not crossed rests with the user.
Do not allow crossed lines to defeat the safety features of the E-Stand, 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.
INTENDED USE:
Flowmeter for a conscious sedation system:
The flowmeter device is intended for patient use and delivers a mixture of nitrous oxide and oxygen
gases during an analgesia (moderate) conscious sedation procedure in a medical healthcare setting by
trained medical personnel. Porter Instrument recommends the user be thoroughly familiar with the use
of Nitrous Oxide - Oxygen Conscious Sedation for patient analgesia and be properly trained in its
administration prior to using this product. For training requirements on the administration of Nitrous
Oxide - Oxygen Conscious Sedation, contact the appropriate regulatory authority in your country, state,
or province. Training is recommended to provide a practical, hands-on capability and an understanding
of the behavioral aspects of Nitrous Oxide Sedation and will complement the safety features of this
device.
INTENDED USE:
Mobile “E” Tank Stand within a conscious sedation system:
The Porter Mobile “E” Tank Stand is for use with two “E” tanks of O
2
and two “E” tanks of N
2
O. The two
pressure gages reflect tank pressure only. When the gas supply is opened, gas will flow through the
check valves into the block and be regulated down to 53 PSIG at the regulators, out through the hoses to
the flowmeter. The check valves prevent the gas from flowing between tanks or out into the room if only
one tank is in use. Each Mobile Stand may be adjusted to a desired height for operatory use and
storage.
