Emergency Procedures
pressure device. Keep in mind, pressure measurement will be available but
pressure-related safety connections will not exist and pumps will not be able to
respond to high pressure events.
• If disconnecting the pressure transducer is not possible, change the Pump
Response to "Message Only". This should prevent potentially erratic pressure
readings from stopping/pausing the pump, if the pressure system malfunction
manifests intermittently.
• Contact Terumo Customer Service after the case is completed.
Unexpected Return to Bypass
• Power up the system.
• Recalibrate the pressure values to quickly resume bypass.
• Set up and prime the circuit per your hospital protocol.
• Calibrate the venous occluder, if used.
• Connect the air and level detection sensors. Resolve any air or level conditions,
reset the air detection system, and turn all air and level systems ON as soon as
possible.
• If using a flow display that is indexed to patient BSA or weight, reenter the patient
height and weight.
• Use the electronic gas blender, recalibration of the oxygen analyzer should not
be necessary, if it has been calibrated within the last 24 hours. The FiO
needs to be reset.
• Verify that the tube size selection is correct.
• Start the arterial pump and attach any other monitoring equipment.
Loss of Gas Supply
Ensure that backup gas sources are available. If tanks are being used, they must be
used with a pressure regulator. The electronic gas blender requires that the source
gases be within a specified range of 50 psi ± 20 psi and that there be no more than
18 psi difference between the inlet pressures of the 2 source gases.
Loss of AC (Mains) Power Supply
Monitor the battery power indicators, such as the power status indicator LED and
the battery charge level bar graph in the Power subtab within the System tab, to
determine the battery charge level status.
Decreasing the power consumption of the system while operating on battery power
can enable the batteries to power the system for more than 1 hour.
Turning off noncritical devices, such as the lamp, will decrease the power needs of
the system.
Loss of Battery Power, Total Power Loss
In the event that the AC (Mains) power supply is lost and the duration of the case
exceeds that of the battery power supply, System 1 pumps and Electronic Gas
Blender may be operated manually to continue perfusion and oxygenation. Safety
devices and their safety connections to pumps will not function after a total loss of
power until power is restored and safety connections are enabled. Instructions for
manual operation of roller pumps are in the Roller Pump chapter, Manual Operation
of Pump section. Instructions for manual operation of centrifugal pumps are in
the Centrifugal Control Unit chapter, Using Standby Equipment section. The
electronic gas blender can be manually operated from the local controls as described
in the Electronic Gas Blender chapter, Local Control of the Electronic Gas
Blender section.
