Ohmeda Excel 210

WLMD ID: alej
Ohmeda introduced its line of Excel anesthesia machines in 1987.  These featured interchangeable parts and integrated controls of several functions that had previously been separate. The Excel machine’s electronic systems included anesthetic delivery, ventilation, carbon dioxide absorption, and monitoring of equipment performance, including audible alarms.  The Excel 210, seen here, has three flowmeters, for oxygen, nitrous oxide, and air, as well as two vaporizers for liquid volatile anesthetics.  The example seen here is equipped with halothane and isoflurane vaporizers.  A fail-safe system ensured that the delivered oxygen concentration did not fall below 25%. This model has three devices housed in the vertical pod on the left, which monitor gas volume, oxygen concentration, and airway pressure. The pod is angled toward the front of the machine, making the monitors easier for the anesthesiologist to see and to reach. Additional monitors could also be attached.

“The company has now made a policy decision to produce a limited range of
machines of constant design features with interchangeable parts and long
service intervals. The Excel machines which reflect this philosophy were
launched for sale in Britain on 12 March 1987…. There are two sizes of
machine, the 410 …. and the 210 a three gas, two vaporizeer model which is
physically smaller.” (Emmett, C. P., T. H. Clutton-Brock and P. Hutton, 1990
p. 581.)
