Draw-over Vaporizers

EMO (Epstein Macintosh Oxford)

The EMO is an ether vaporizer, with both thermal buffering (a water jacket) and automatic thermo-compensation.

Manufactured by Penlon

OMV (Oxford Miniature Vaporizer)

The OMV has thermal buffering (water and antifreeze) but full thermo-compensation is not necessary. It can be used with halothane, trichlorethylene, enflurane, isoflurane, sevoflurane.

Manufactured by Penlon

PAC series

Ether-PAC and Fluo-PAC (Halothane) have automatic thermo-compensation.

Manufactured by Datex-Ohmeda, now GE Healthcare.

Bryce-Smith Induction Unit (BSIU)

These are no longer manufactured.

If a BSIU is available it is very useful to facilitate induction when using the EMO ether vaporizer. It is a simple no-controls vaporizer which delivers 3 - 4 mls of halothane to precede, and assist induction with, ether.

Originally manufactured by Penlon

Goldman

A simple vaporizer (no longer made) useful for halothane.

Komesaroff

Similar to the Goldman but with gradations on the glass bowl indicating volume.

Glostavent Vaporiser

Suitable for both draw-over and continuous flow, and for most agents.  Capacity 150 ml.

Anaesthesia Systems

Glostavent

The Glostavent is a unit comprising:

• a Diamedica Glostavent vaporizer (drawover and continuous flow)
• a Diamedica AP ventilator
• an oxygen concentrator
• a draw-over ‘circuit’ with reservoir, supplementary oxygen inlet, self-inflating bag and one way valve

These are now manufactured by Diamedica but useful information can also be found on the original web site: www.glostavent.com

Diamedica Portable Anaesthesia System

"A complete draw-over anaesthesia system in a case. The anaesthetic is delivered by the Glostavent™ Draw-over vaporizer. It comes complete with adult and paediatric circuits."

Manufactured by Diamedica

Komesaroff Anaesthesia Machine Mk 5

Manufactured by Medical Developments International
Web site: www.medicaldev.com (see ‘catalogue’)

This equipment includes two 2-way low resistance vaporizers and can be used in the closed (?semi-closed) circle mode or, when necessary, in the draw-over mode.

[Coyle: Its use is advisedly restricted to experienced medical anaesthetists, unless so modified temporarily that it can only be used in the draw-over mode.]

Tri-Service Anaesthetic Kit

Manufactured by Penlon

Originally developed for military field use, the Tri-Service Kit has 2 OMVs (Oxford Miniature Vaporizers) and is designed primarily for use with adults in the draw-over mode. It includes the necessary items to allow oxygen supplementation.

The Tri-Service can be readily adapted for paediatric use.

For children under 15 kg

• spontaneous ventilation (advisedly for only short periods of time) via a modified T-piece. A tube (eg an ETT - Endotracheal tube - 9.0-9.5 mm diameter) is attached to the suction port of the catheter mount, with gas flow provided by rapid-rate compression of the SIB (self inflating bag).
• controlled ventilation - suction port is occluded while squeezing the SIB and opened for expiration.

ULCO FAM100 Mk2 Field Anaesthesia Machine

ULCO Medical, Australia

This is primarily a military field kit with the option of plenum or draw-over modes of function.

[Coyle: Non-military use is probably best confined to experienced medical anaesthetists.]
