CAUTION
• Only personnel instructed and trained in its use should operate the
Conserver.
• The Conserver contains magnetic, ferrous material that may affect
the results of an MRI.
• DO NOT autoclave.
• DO NOT gas sterilize with Ethylene Oxide.
• DO NOT clean with aromatic hydrocarbons.
• Store the Conserver in a clean area when not in use.
• Avoid dropping the Conserver or placing it in a position where it could
fall and become damaged.
• Consistent with the recommendations of the medical community on
the use of conserving devices, it is recommended that the Oxygen
Conserving Regulator be qualified on patients in the situations it will
be used.
• The Conserver may not be able to detect all respiratory efforts of the
patient. (Shallow breathers may not be able to trigger the Conserver.)
• Operating the Conserver outside its range of operating conditions
may affect its accuracy and performance.
PRINCIPLES OF OPERATION
The Oxygen Conserver is designed to be used with high-pressure oxygen
systems. It consists of a cylinder connection, cylinder contents gauge (if
equipped), high-to-low pressure regulator, orifice plate and a conserving
demand module. The regulator reduces the high pressure of the cylinder to
the working pressure of the orifice plate. The orifice plate uses calibrated
orifices to deliver a selected flow to the conserving demand module. The
conserving demand module controls the pulse size and timing to the
patient. It supplies a pulse of oxygen at the beginning of each breath.
This reduces the oxygen demand on the system and limits the drying of
the airways. The flow is determined by setting the flow control knob to the
prescribed flow. The oxygen is supplied to the patient through the cannula.
