A case is reported of hypoxia occurring during anaesthesia in a spontaneously breathing ASA I patient. The patient became cyanotic twice when breathing a gas mixturee delivered by a safety mixer. Changing the machine solved the immediate problem. The diagnosis was difficult to make because the rotameters all showed normal delivery of oxygen and nitrous oxide. Oxymetry elucidated the cause, which was found to be a defective rapid oxygen control. Because these machines do not appear to be… Expand

Five oxygen-nitrous oxide proportioning systems compared.
TLDR
All the modules investigated prevented the delivery of hypoxic fresh gas flows both under normal and abnormal working conditions (unequal supply of gas pressures) and all systems showed increased O2 concentrations atfresh gas flows below 1 L min-1. Expand
Nitrous oxide-oxygen administration: when safety features no longer are safe.
TLDR
12 safety features used to ensure the safety and efficacy of nitrous oxide-oxygen sedation are reviewed, including the pin-index safety system, which prevents the accidental attachment of a nonoxygen tank to the oxygen attachment portal, and diameter-index systems help ensure that the appropriate gas flows through the appropriate tubing.

TLDR
La mise hors circuit un a un des respirateurs branches sur ce circuit a permis d'identifier un respirateur, plus precisement son melangeur, comme responsable of the reinjection d'air. Expand
