MONITORING SYSTEM
GENERAL DESCRIPTION
The
NARKOMED
standard, integral monitors:
BAROMED breathing pressure monitor
O
MED oxygen analyzer

O
SATMED pulse oximeter
2
SPIROMED respiratory volume
monitor
MULTISPEC respiratory gas analyzer
SPHYGMOMED noninvasive blood
pressure monitor
Figure 15 illustrates the front panels of the
monitors. Each monitor consists of a modular
chassis that mounts in a monitoring rack to
the right of the monitoring system display
screens.
O
MED Oxygen Analyzer

The O
MED uses a dual redundant galvanic
2
cell sensor to monitor and digitally display the
oxygen concentration in the patient breathing
system. The operator can set low and high
oxygen concentration alarm limits, calibrate
the monitor to 21% oxygen with a single
keystroke, and view oxygen concentration
data on a trend graph display. An O
alarm warns of sensor cable disconnection,
sensor malfunction, and sensor degradation.
The unit can also (through alarm messages
on the central alarm display) alert the
operator that a calibration is due or that an
internal electronics malfunction has occurred.

Operator's Instruction Manual.

BAROMED Breathing Pressure Monitor
The BAROMED monitors breathing system
pressure at either the absorber or the Y-piece.
The unit can display mean, peak, or positive
end expiratory (PEEP) pressure in cm H
The operator can set alarm limits for high
pressure
and
threshold
adjustment keys. Alarms are provided for
high pressure, pressure below threshold for 15
and 30 seconds, subatmospheric (< -10 cm

pressure,

continuing pressure above the set threshold
for 15 seconds. Also, the unit can alert the
operator of an improperly set threshold
pressure
with
the
"THRESHOLD LO" on the central alarm
display. A detailed description and operating
instructions can be found in the BAROMED
Operator's Instruction Manual.
SPIROMED Respiratory Volume Monitor
The SPIROMED uses a positive displacement,
rotating-lobe impeller sensor to monitor and
display tidal volume, minute volume, and
respiratory rate. The operator can set a low
alarm
limit
for
minute
adjustment keys. A fixed alarm warns of
reverse flow through the sensor. An apnea
alarm is generated if the sensor does not
sense a breath for 15 and 30 seconds. A
volume sensor alarm activates if the sensor
cord is disconnected or damaged. A detailed
description and operating instructions can be
found in the SPIROMED Operator's In-
struction Manual.
