15.8 IBP Calibration
Calibration points for mercury pressure gauge:
Mercury pressure gauge calibration should be carried out when a new sensor is used or in accordance with the period
specified by the hospital procedure.
The purpose of the calibration is to ensure that the system provides an accurate measurement. Before starting a
calibration by the mercury pressure gauge, a zero procedure must be performed. If you need to perform this procedure
by yourself, you need the following equipment:
n
Standard sphygmomanometer
n
T-shape connector
n
Tubing(approximately 25 cm)
The calibration procedure for mercury pressure gauge:
IBP Calibration
WARNING
l
You must never perform this procedure while the patient is being monitored.
1.
Zeroing must be performed before starting the mercury pressure gauge calibration.
2.
Connect the tubing to the sphygmomanometer.
3.
Ensure that the connection to patient is off.
4.
Connect one end of the T-shape connector to the 3-way stopcock, the other end to the gasbag, the third end to the
