Abstract

An anti-asphyxiation valve is disclosed, which is adapted for incorporation within a breathing circuit including a ventilator. The valve comprises one or more apertures for enabling passage of gas between the breathing circuit and the atmosphere, and a valve member deformable between an open configuration in which the one or more apertures are at least partially exposed and the passage of gas therethrough is enabled, and a closed configuration in which the valve member occludes the one or more apertures and the passage of gas therethrough is substantially prevented. The valve member is adapted such that the pressure within the breathing circuit at which the valve member deforms from the open configuration to the closed configuration is greater than the pressure within the breathing circuit at which the valve member deforms from the closed configuration to the open configuration.
