Philips MP20/30, MP40/50 Zeroing the Pressure Transducer, Selecting a Pressure for Monitoring

12 Monitoring Invasive Pressure Zeroing the Pressure Transducer

WARNING If measuring intracranial pressure (ICP) with a sitting patient, level the transducer with the top of the patient’s ear. Incorrect leveling may give incorrect values.

Selecting a Pressure for Monitoring

Tell the monitor which pressure you want to monitor by selecting its pressure label. The label is a unique identifier for each type of pressure. When you chose a label, the monitor uses that label’s stored color, wave scale and alarm settings.

1In the Setup <Press> menu, select Label.

2Select the appropriate label from the list.

Label	Description	Label	Description
ABP	Arterial blood pressure	P	Non-specific pressure label
ART	Arterial blood pressure (alternative)	PAP	Pulmonary artery pressure
Ao	Aortic pressure	RAP	Right atrial pressure
CVP	Central venous pressure	UAP	Umbilical arterial pressure
ICP	Intracranial pressure	UVP	Umbilical venous pressure
LAP	Left atrial pressure

Extended Pressure Label Set

The following additional labels are available if Label Set is set to Full. This setting can only be changed in Configuration Mode.

Note that if your monitor is connected to an Information Center, the additional labels in the extended label set may not be correctly displayed. See the Configuration Guide for your monitor for more information.

Label	Description
BAP	Brachial arterial pressure
FAP	Femoral arterial pressure
IC1, IC2	Alternative intracranial pressures
P1, P2, P3, P4	Alternative non-specific pressure labels

Zeroing the Pressure Transducer

To avoid inaccurate pressure readings, the monitor requires a valid zero. Zero the transducer in accordance with your hospital policy (at least once per day). You must perform a zero:

•when you use a new transducer or tubing

•every time you reconnect the transducer cable to the monitor

•if you think the monitor’s pressure readings are not correct.
