The Spencer Flex Mask is composed of a valve with non-rebreathing membrane, connected to a resuscitation mask. It prevents from "mouth to mouth" contact between patient and operator. It can be employed when patients are not able to breath spontaneously.
The air flow can be enriched with oxygen by removing the cap on the mask and inserting an oxygen feeding tube.
Transparency of the mask allows the operator to monitor any regurgitating of the patient throughout the resuscitation process and the soft cushion guarantees perfect adherence to the patient's face.
