Caution
The stopcocks of the converter or the outlet should be locked before
connecting the door-lock plug.
Note
<< Priming and Tips >>
● Priming should be done slowly!
- Slow priming will lessen the effort to remove air bubbles afterward.
● Priming using gravity!
- Pressing may result in leakage of liquid or bubbles by forcing the
liquid to flow into the system. If small bubbles flow too slowly
inside the system, lift up the supply bag. 1 inch corresponds to
2mmHg, and the primed 4-feet line gives a pressure of about
100mmHg if it is completely spread out The solution bag should
be placed at a higher position than the converter and the pressing tube,
in order for priming using gravity.
Caution
If air foam or bubbles are present inside the system, it may cause
significant bias of the pressure waveform or air embolism.
Care should be taken not to let air bubbles inside the 3-way outlet
stopcock or the cannula reflush into the patient. To check, confirm if
the monitoring line is fully filled with liquid before connecting the
monitoring line and let a small volume of blood flow through the
cannula.
10.3 Adjustment of Zero point of the Converter
1) Lock the zero point stopcock (toward OFF) and release the converter according to the air
pressure.
2) Set “Menu”-> “Zero”-> “Yes” in order. If final value is “0”, the measurement starts.
