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 Conserver
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.
