clear cuff. Flush the system for 2~3 seconds. Check for the
presence of air bubbles which may result from a fast flush. Now,
the system is ready for zero point setting and measuring. Place the
stopcock in a 90 degree position to let it off state. Be sure to never
position it at 45 degrees. A wrong setting of the stopcock handle may
cause infection, bleeding, or air embolisms in the patient.
◈ 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.
Zero Point Adjustment of the Converter
1. Place the zero point port at the area of the right atrium, the middle
of the axilla, and the fourth intercostals area, and then place the
converter and the kit in a proper operating site. Some version of
the blood pressure conversion kit is provided with the patient’s IV
rod or the accessories needed for various settings.
2. Lock the zero point stopcock (toward OFF) and release the
converter according to the air pressure.
3. Conduct zeroing by pushing the zeroing button of the module or
select zeroing-one from the menu in the IBP setting menu.
