Priming of Anesthesia Circuit with Xenon for Closed Circuit Anesthesia

Artificial Organs, 1997
Abstract: Xenon is an inert gas with a practical anesthetic potency (1 MAC = 71%). Because it is very expensive, the use of closed circuit anesthesia technique is ideal for the conduction of xenon anesthesia. Here we describe our methods of starting closed circuit anesthesia without excessive waste of xenon gas.

Adaptive control of closed-circuit anesthesia

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1988
Closed-circuit anesthesia (CCA) is more economical and ecologically safer than open circuit anesthesia. However, gas concentrations are more difficult to control. Computer control of CCA has been proposed to facilitate its use. Past efforts have either been limited to the control of anesthetic gas concentrations or apply only to a small group of ...

Closed Circuit Anesthesia in Infants and Children

Anesthesia & Analgesia, 1984
A closed-system low-flow technique with enflurane, halothane, or isoflurane as the sole anesthetic was used in three groups of ten children each. Anesthesia was induced by injection into the expiratory limb of a priming standard dose of the liquid anesthetic, followed by additional doses at 15, 30, 60, and 90 sec, and 2, 3, and 4 min.

Adaptive control of multiplexed closed-circuit anesthesia

IEEE Transactions on Biomedical Engineering, 1992
This paper describes the design of an adaptive closed-circuit anesthesia controller based on a multiplexed mass spectrometer system. The controller deals with measurement deterioration caused by measurement delay and rise time through a long catheter as well as long sampling times due to the multiplexed measurements.

Methane Accumulation During Closed-Circuit Anesthesia

Anesthesia & Analgesia, 1994
When using the closed-circuit PhysioFlex apparatus for ventilating patients with an O2/air mixture during total intravenous anesthesia (TIVA) for gynecologic laparoscopy, we noticed that the built-in infrared analyzer indicated unexpected values for halothane.

A pharmacokinetic model of closed-circuit inhalation anesthesia

Annals of Biomedical Engineering, 1978
A mathematical model consisting of six well-mixed tissue compartments was used for prediction of an anesthetic dose rate designed to maintain a constant arterial halothane concentration during closed-circuit anesthesia with halothane and nitrous oxide. Metabolism of anesthetics was not considered they were regarded as inert.
