Safe vaporizers

Overfill testing of anaesthetic vaporizers.

We tested six anaesthetic vaporizers with keyed filler adaptors to see if it was possible to overfill them. For those vaporizers which could be overfilled, the maximum level of overfill was determined and the effect of overfilling on the vaporizer output concentration was measured. Three of the vaporizers, the TEC 4, PPV Mk 1 and MIE Vapamasta 5, could be overfilled. In the case of the TEC 4 an...

Accuracy of halothane vaporizers in clinical use.

Evaluation of keyed fillers on TEC vaporizers.

Single and dual port versions of the keyed fillers fitted to TEC4 and TEC3 vaporizers, respectively, were examined. The single port filler performed satisfactorily, provided that it was correctly used and properly maintained. Design deficiencies in the dual-port keyed filler were found which accounted for many of the problems described by users. The keyed bottle adaptor could be improved by an ...

A clinical and laboratory evaluation of four fluothane vaporizers.

WIDESPREAD CONTINUING INTEREST in 2 brom, 2 chlor 1, 1, 1, fluoroethane, known as halothane or more commonly Fluothane, has resulted over the past few months in many attempts to make its use sas and at the same time more economical. Certain apparatus has been designed to facilitate its use, particularly by the less experienced anaesthetist. This paper describes the clinical and laboratory inves...

Comparison of Traditional and Integrated Digital Anesthetic Vaporizers.

Recent efforts have focused on mitigating anesthetic gas emissions during laboratory animal experiments. A recently developed, digitally controlled, integrated digital vaporizer (IDV) using a syringe pump has been designed to use and administer anesthetic gas to mice and rats more efficiently. The entire IDV system can be placed on a laboratory bench, requires fewer charcoal filters to act as p...
