Narkomed GS

WLMD ID: ammf
North American Dräger (NAD) followed the Narkomed 4 anesthesia machine with the 1997 introduction of the Narkomed GS. The GS was more compact and featured a single monitoring screen (as opposed to the double screen on the Narkomed 2 through 4), a much simplified monitor user-interface, and a new color scheme. In 1999, NAD merged with another Drägerwerk AG subsidiary, Dräger, Inc., to form Draeger Medical, Inc. For this reason, some Narkomed GS machines were manufactured by NAD and others by Draeger Medical, Inc. Production of the GS ceased in 2006.

With the GS, the Narkomed’s standard monitors were whittled down to inspiratory oxygen concentration, respiratory volume, and breathing system pressure.  Also of note, the GS was the last Narkomed built with one of NAD’s “AV” series of ventilators, specifically the “AV2+.” This was a pneumatically driven, double-circuit ventilator with one ventilation mode: volume control. The Narkomed 6000, introduced in late 1998, came with the electrically driven Divan (Digital Ventilator for Anesthesia) Ventilator, which allowed for multiple ventilation modes.

The GS pictured here was once part of the James Yoder Teaching Collection of North American Dräger. Mr. Yoder was an 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 became the basis for the museum which was located at the headquarters of NAD in Telford, Pennsylvania.

Notes: North American Dräger(NAD) followed the Narkomed 4 anesthesia machine with
the 1997 introduction of the Narkomed GS. The GS was more compact and
featured a single monitoring screen (as opposed to the double screen on the
Narkomed 2 through 4), a much simplified monitor-user interface, and a new
color scheme. In marking the GS, NAD emphasized its “user friendly interfaces
and intuitive controls.” In 1999, NAD merged with another Drägerwerk AG
subsidiary, Dräger, Inc., to form Draeger Medical, Inc. For this reason, some
Narkomed GS machines were manufactured by NAD and others by Draeger Medical,
Inc. The machine pictured here bears both names. Production of the GS ceased
in 2006.

With the GS, the Narkomed’s standard monitors were whittled down to
inspiratory oxygen concentration, respiratory volume, and breathing system
pressure. Also of note, the GS was the last Narkomed built with one of NAD’s
“AV” series of ventilators, specifically the “AV2+.” The Narkomed 6000,
introduced in late 1998, came with a Divan (Digital Ventilator for
Anesthesia) ventilator. The AV2+ was a pneumatically driven, double-circuit
ventilator with one ventilation mode: volume control. The Divan was an
electrically driven, piston ventilator that allowed for multiple ventilation
modes: volume control, pressure control and
synchronized-intermittent-mandatory ventilation.

The GS pictured 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
