13 Monitoring Invasive Pressure
1 Tubing to manometer
2 Syringe with heparinised solution
3 To pressure connector on monitor
4 Patient connection stoppered
Move the syringe barrel in and raise the mercury to 200 mmHg (30 kPa). 200 mmHg is the
recommended calibration pressure.
Select the calibration pressure from the list, for example 200 mmHg.
When the monitor displays
manometer tubing, syringe and extra stopcock. We recommend you replace the transducer dome
and tubing with sterile ones.
Label the transducer with the calibration factor shown in the
