Fig 16-5 Connection layout of IBP pressure calibration
Calibration of the mercury manometer should be done when a new sensor is being
started to use or at the specified cycle in the hospital practice.
The purpose of calibration is to ensure the system to provide accurate measured results.
Before calibration of the mercury manometer, pressure zero calibration should be done.
If the procedure is to be carried out by yourself, you should have the following devices.
z standard blood pressure gauge
z three-way stop cock
z pipeline with a length of about 25cm
17.6 Mercury manometer calibration procedures:
Warning
The following operation should never be done when a patient is being monitored.
① Close the three-way stop cock which is opened to the atmosphere for zero calibration.
② Connect the pipeline with the blood pressure gauge.
③ Confirm that connection to the patient has been off.
④ Connect a three-way stop cock with the three-way joint that hasn’t been connected to
the patient catheter (when the patient is being monitored). Connect a syringe to one end
of the three-way stop cock and connect the blood pressure gauge and the pipeline with
blood pressure gauge
