A pressure limiting valve for anaesthetic and respirator circuits

  • H. T. Norry
Article

Summary

A simple pressure limiting valve is described which can be adapted to any anaesthetic machine and which effectively prevents the development of dangerously high pressures in the breathing circuits attached to the patient’s airway. Such a safety valve should be incorporated as standard equipment into all anaesthetic machines.

Réesumé

Nous avons décrit une valve simple destinée à limiter la pression dans le circuit respiratoire existant entre le malade et ľappareil à anesthésie. Cette valve peut s’adapter à tout genre ďappareil et elle prévient la formation de pressions dangereusement é1evées.

Une telle valve devrait faire partie de ľéquipement standard de tout appareil servant à administrer ľanesthésie.
