Electronic Gas Blender; Features - Terumo Advanced Perfusion System 1 Operator's Manual

Electronic Gas Blender

Features

The electronic gas blender provides control and monitoring of the gas flow rate and
oxygen content of the gas input to the oxygenator in the perfusion circuit. It also
provides monitoring of the carbon dioxide if 95% oxygen / 5% carbon dioxide (95/5) is
used as the blending gas instead of air.
The electronic gas blender is an optional component of the Terumo
Perfusion System 1 and it is integrated into the system base. A multicolored LED on
the electronic gas blender provides status indications to the user. The electronic gas
blender contains an integrated oxygen analyzer to measure the oxygen content of the
blended gas.
If the electronic gas blender is included with the System 1, it will automatically appear
in the Perfusion Screens that are used with that system. No additional configuration
is required by the user. When a gas blender is installed after Perfusion Screens have
been created, check to ensure the Gas Blender icon does not obscure other device
icons that are on the Perfusion Screen. Some device icons may need to be moved.
The electronic gas blender can be controlled from the Central Control Monitor (CCM)
or from the FiO and flow control knobs located on the front panel of the system base.

These two control systems are linked such that if a change is made to the FiO
the flow rate using one set of controls, that change is reflected on the other set of
controls.

WARNING: When using a microporous membrane oxygenator, negative pressure
pulses (which can result from abrupt decreases in arterial flow) may introduce
gaseous emboli into the blood by creating blood pressures lower than the gas
path pressure. Monitor arterial line pressure and adjust the pump so that pressure
in the blood compartment of the oxygenator is always greater than the gas path
pressure.
WARNING: Use clean, dry, medical grade gases and keep the water trap empty
as liquid water or other contaminants in the gas supplies will cause malfunction of
this system.
