An anaesthetic vaporiser is a device that is typically attached to an anaesthetic machine which delivers a given concentration of a volatile anaesthetic agent. The purpose of an anesthetic vaporizer is to produce a controlled and predictable concentration of anesthetic vapor in the carrier gas passing through the vaporizer.
Below, we will address the both the hazards and safety features of contemporary vaporizers.
- Incorret agent
- Tipping - if tipped more than 45 degrees from the vertical, liquid agent can obstruct valves.
- Simultaneous inhaled agent administration
- Reliance on breath by breath gas analysis rather than preventative maintenance
- Electronic failure
Consequences of Not Maintaining Vaporizers:
- Patient death
- Patient awareness (of surgery going on even though they cannot move or speak. This can also be considered anesthetic awareness)
- Regaining consciousness
- The vaporizer jams up and the surgery can not continue
- The patient is injured - there is mental and physical trauma
- Keyed vaporizers
- Low filling port
- Secured vaporizers
- Concentration dial increases output when rotated clockwise
