SUPPLY PRESSURE”, “AC POWER FAIL”, “BATTERY LOW”, “BATTERY TEST”; Below the
indicator lights is the system power dial with a position marked, “ON,” and
another position marked “STANDBY”; To the right of these lights and dials is
the gas flowmeter and pressure gauge assembly; Both nitrous oxide (marked
“N20” and color coded blue) and oxygen (marked O2 and color coded green) have
a coarse and fine flow tube, as well as pressure gauges for pipe and cylinder
sources; Between the nitrous oxide (on the left) and oxygen (on the right) is
a flowmeter for air (color coded yellow with calibration marks from .2 to 10)
and a flow meter for carbon dioxide (colored yellow and marked “CO2” with
calibration marks from .05 to 1.0); Each of these flowmeters has one
corresponding pressure gauge below the flowmeters; To the right of the
flowmeter assembly are the vaporizers; There are three Vapor 19.1 vaporizers
attached to the back bar; From left to right they are, “Halothan” (with a
color code bar of red), “Enflurane” (with a color code bar of orange), and
“ISOFLURANE” (with a color code bar of purple); Just above the three
vaporizers is a dial with two settings; One is marked, “02 + N20” and the
other is marked “ALL GASES”; Most of the housing of the machine thus far
described (located above the table top) is black, with the exception of the
sides which are Dräger blue; … [continued at 2].

left side of the machine is the breathing system which includes, a dual
absorber canister, PEEP controls, a manual/automatic ventilation selector,
visible inspiratory and expiratory valves, a breathing system pressure gauge,
and oxygen sensor; Also extending from the left side of the machine is an
adjustable arm for the remote monitor; On the back of the monitor is a
manufacturer’s label with the following markings: “NORTH AMERICAN DRÄGER [new
line] 148B Quarry Road [new line] Telford, PA. 18969 USA [new line] MODEL
411 2314 [new line] SER. NO. 10733; On the left upper side of the machine are
a number of ports for monitoring equipment, including the port for the
“DATAGRIP” for the remote monitor, a port for the remote monitor itself, a
dual blood pressure cuff and blood pressure gauge, oximeter sensor, and
another BP cuff port; Further back, on the upper left side of the machine, is
a space for a water trap; Additional ports are located on the left side of
the machine below the ventilator bellows; They include oxygen sensor, volume
sensor, breathing pressure and selector/exhaust; An open reservoir scavenger
is located on the lower back of the left side of the machine; The body of the
scavenger is cream colored; Most of the panels on the back of the machine
have been removed to expose the computer components and the anesthesia system
components; Because of this, the model number for the machine is not on the
back; Power outlets are located on the upper left back of the machine; On the
upper right of the back of the machine is the external communication
interface panel; This contains connections for external monitors or a
centralized monitoring system; On the inner side of the flowmeter assembly,

Note Type: Historical
Notes: The Narkomed 4, manufactured by North American Dräger (NAD), was introduced
in 1990. Differences between it and the Narkomed 3 were especially notable in
the design of the onboard computer. The Narkomed 4 included dual processors,
a build-in 3.5 inch floppy disk drive, a keyboard, and a dual display touch
screen.

The new software was named “O.R. Data Manager” (ORDM). The information that
the software could record was limited to numerous predetermined “pick lists”
and short fill-in-the-blank fields. ORDM allowed anesthesia providers to
create patient records, add patient biographical data, and document basic
case information, core events (start of anesthesia, start of surgery, patient
exits OR, etc.), and medication & fluid administration. Data from the
machine’s monitors was automatically entered into the record every 30 seconds
The patient record could be saved to a floppy disk or to a network drive
disk. During the 1990s completed records were often printed, augmented and
added to the patient’s paper record.

Six monitors sent data to the ORDM and the display screen. The variables
monitored were inspiratory oxygen concentration, pulse oximetry, respiratory
volume, respiratory gas concentrations (carbon dioxide, nitrous oxide, and
anesthetic agents), breathing system pressure, and blood pressure. Patient
temperature, which had been incorporated into the Narkomed 3, was omitted in
the Narkomed 4. A variety of interface controls (touch-screen, push buttons,
rotary dial, keyboard and remote monitor “datagrip”) could be used to adjust
what data was displayed, as well as how it was displayed.

Also new to the Narkomed with the Narkomed 4 was a strip printer, data ports
for external NAD devices and network connection, and a back-up battery.

NAD reported that more than 100,000 engineering hours were invested into the
design of the Narkomed 4. The GS described here was once part of the James
Yoder Teaching Collection of North American Dräger. Mr. Yoder was a NAD
machinist and educator. Originally Mr. Yoder maintained the collection of NAD
equipment for the purpose of educating anesthesia providers and machine
technicians. Later the collection was used to form the museum, which was
located at the headquarters of NAD in Telford, Pennsylvania.
