Using Multi-parameter Sockets for CO and CO
2
Monitoring
WARNING
••
••
• When performing defibrillation during CO monitoring, never touch the CO connection cord. Otherwise the
discharged energy may cause electrical shock or injury.
••
••
• When performing defibrillation during CO
2
monitoring with the CO
2
sensor kit, remove the sensor from the
patient. If the sensor cannot be removed, do not touch the sensor cable because the discharged energy
may cause electrical shock or injury.
NOTE
••
••
• CO monitoring using the multi-parameter socket does not comply with the Defibrillator proof type CF.
••
••
• CO
2
monitoring using the multi-parameter socket does not comply with the Defibrillator proof type BF.

Using the Output Signal from the ECG/BP OUT Socket
WARNING
When using the output signal from the monitor as the synchronization signal for other equipment such as
an IABP (intra-aortic balloon pump) or defibrillator:
••
••
• Set the timing of the IABP by checking the waveform on the IABP screen.
••
••
• Check the condition of the bedside monitor at all times. The output signal may become unstable.
••
••
• Check that the delay time of the output signal (heart rate trigger 64 ms maximum) is within the range of
the connected equipment.
••
••
• Do not use the heart rate trigger as the synchronization signal for defibrillator.
NOTE
The output signal from the ECG/BP OUT socket may become unstable in the following conditions.
••
••
• Electrode is dry or detached.
••
••
• Electrode lead is damaged or disconnected from the electrode.
••
••
• Electrode lead is pulled.
••
••
• AC interference or EMG noise superimposed.
••
••
• Air bubbles or blood clog in the circuit for monitoring IBP.
••
••
• Cord or cable is disconnected or damaged.
