Instrumentation for inhalation anesthesia: Present state and trends of development

Conclusions

1. Inhalation anesthetizers occupy a significant place in medical equipment production and a tendency is observed for companies which earlier specialized only in the production of vaporizers and monitors to now undertake the production of inhalation anesthetizers.

2. The only principally new approach was manifested in the “Engstrom-Elsa” completely electronic system previously exhibited at the “Hospital-88” and “Hospital-89” exhibitions.

3. Inhalation anesthetizers tend to incorporate digital monitors for oxygen, carbon dioxide, and vaporized anesthetic concentration, as well as pulsoximeters and hypoxia protectors. Modular architecture and functional design are new features.

4. Urgent development and production of pulsoximeters and monitors to measure concentration of vaporized anesthetic agents (flurothane and ether) is required in the USSR.
