OPERATING INSTRUCTIONS (continued)
Blood Pressure Display
The
Blood
Pressure
display
on
the
VITALERT 2000 is separated into two
channels (P1 and P2). Each channel has four
sections: the blood pressure waveform, the
blood
pressure
waveform
scale,
blood
pressure measurements, and blood pressure
alarm limits. A description of each section is
given below.
Blood Pressure Waveforms
The VITALERT 2000 updates and displays
both P1 and P2 invasive pressure waveforms
in the same manner as the ECG waveform,
using the moving “blank bar.”
Blood Pressure Channel Labels
The VITALERT 2000 labels the P1 pressure
channel
P1
ART
to
indicate
arterial
pressure. The P2 pressure channel can be
labeled for central venous pressure (P2
CVP), pulmonary artery pressure (P2 PA),
or as a second arterial pressure (P2 ART).
The P2 pressure channel label may be
selected via the Configuration mode.
Blood Pressure Waveform Scales
The VITALERT 2000 displays a graphic
pressure scale to the left of the waveform for
each blood pressure trace. Either manual or
automatic pressure scaling can be selected
via the P1 Scale and P2 Scale functions in
the Configuration Mode. Manual scaling
allows the operator to select from the
following fixed scales (mm Hg):
•
Arterial: 60–90, 60–135, 50–200, 0–300
•
CVP and PA: 0–15, 0–30, 0–75, 0–150,
0–300
Automatic arterial scaling selects a scale
5–20 mm Hg larger than the pulse pressure
centered about the waveform.
CVP or PA pressures are shown on a scale
where the lower boundary is zero and the
upper boundary is 5–10 mm Hg above the
systolic pressure.
Blood Pressure Measurements
The VITALERT 2000 displays the systolic,
mean, and diastolic values to the right of
each pressure waveform.
Blood Pressure Alarm Limits
High and low alarm limits are provided for
the P1 systolic pressure and P2 ART
(systolic), P2 CVP (mean), or
P2
PA
(diastolic)
pressure
(depending
on
configuration selection). These alarm limits
are displayed immediately to the right of
their respective measurements. Both high
and low limits for each of the two pressure
channels can either be adjusted in the
Configuration mode or directly on the
Monitor screen using the HI, LO, INC, and
DEC keys in the BLOOD PRESSURE
ALARM section of the main keyboard. While
being adjusted on the Monitor screen, the
selected limit is enclosed in a box.
Temperature Display
The Temperature display on the VITALERT
2000 is separated into two channels (T1 and
T2). Patient temperature measurements are
displayed in the lower left section of the
screen.
The
units
of
measure
for
temperature are degrees Celsius or degrees
Fahrenheit. The units of measure can be
selected in the Configuration mode.
Alarm Display
The Alarm display occupies the bottom of
the Monitor screen. As alarm conditions
occur, alarm messages (such as HRT RATE
LOW)
are
indicated
in
one
of
three
categories of the Alarm display: Warning,
Caution, and Advisory. Each type of alarm
message produces a different sound pattern:
