Invasive Pressure Messages

The following messages can appear in the numerics window.

NOT ZEROED (or NO ZERO).

No zero reference has been established. The monitor

displays the pressure waveform, but to protect against erroneous readings, the pressure
waveform scale is not displayed. To remove this message, zero the transducer.

ZEROING.

This message briefly appears as the transducer is being zeroed.

ZEROED.

This message appears after the zero value has been accepted. It remains for

eight seconds and is replaced by the current pressure values.

RANGE

Sets the display to Range Mode. All invasive pressure waveforms monitored
are displayed against the same scale. You can select one of five Propaq Encore
pressure scales. If two waveforms have a great difference in their pressures, the
higher pressure waveform may not be visible if it is out of range of the scale.
Press

RANGE

until the desired scale appears.

RESCALE

Sets the display to Rescale Mode. Each invasive pressure waveform is
displayed against its own scale. Each time you press the button, the scale is
automatically selected based on the highest and lowest pressure levels of each
pressure waveform.

ZERO

Zeroes the selected pressure channel, or cancels zeroing in process.

CANCEL

The

ZERO

button changes to

CANCEL

while zeroing.

LABEL

Selects a label for the pressure channel. The selectable labels are:
ART—arterial, PA—pulmonary artery, CVP—central venous pressure, ICP—
intracranial pressure, UA—umbilical artery, and UV—umbilical vein.

You can still use the generic Propaq Encore pressure label, P1 or P2.

FORMAT

The Propaq Encore displays the invasive pressure values in two different
numeric formats in the pressure numerics window. You can select which
pressure value(s) are most prominently displayed.
