Abstract
The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.
