12.1 Introduction
Invasive Blood Pressure (IBP) is a direct measurement of the patient's arterial or venous blood pressure. A
catheter is used and inserted directly into a vein, artery or other pressure access areas, and is connected to
a pressure transducer for measuring systolic, diastolic and mean blood pressures. The device can choose to
monitor 2 or 4 (for specific model) channels IBP depending on the configuration. The device can display the
systolic, diastolic and mean blood pressures and a waveform for each pressure channel.
12.2 Safety Information
Warning
The pressure tube which connects the catheter and the pressure transducer should be
straightway without any tangle.
Use the pressure transducer kit specified in this manual. Never reuse disposable pressure
transducers.
Make sure that the applied parts never contact other conductive parts.
To reduce the hazard of burns during high-frequency surgical procedures, ensure that the
monitor's cables and transducers never come into contact with the high-frequency
surgical units.
When using accessories, their operating temperature should be taken into consideration.
For details, refer to instructions for use of accessories.
Use the accessories specified by the manufacturer, when a defibrillator is used.
Improper use of a defibrillator may cause injury to the patient. The user should determine
whether to perform defibrillation or not according to the patient's condition.
Before defibrillation, the user must ensure both defibrillator and monitor have passed the
system test and can be safely used jointly.
Do Not use the damaged pressure tube and transducer.
If air bubble appears in pressure tube, please fill the tube with saline solution again. Air
bubble may cause inaccurate reading.
When doing ICP measurement to the patient who is sitting, please keep the pressure
transducer and the top of patient's ear at the same level, or it may lead to error reading.
When unplugging the cable from the monitor, be sure to hold the head of the connector
and pull it out.
Each time when connecting transducer kit or using a new transducer kit, zero calibration
to the IBP transducer must be carried out.
Before using the tube, cable and/or transducer, make sure that all accessories meet the
Chapter 12 Monitoring IBP
