Spencer Flex Mask comprises a one-way valve, which is connected to a resuscitation mask, made in a latex free material. It prevents mouth to mouth contact. Flex Mask can be used any time a situation arises, in which a patient in respiratory arrest has to be resuscitated. The air flow can be enhanced with oxygen by removing the cap on the mask and by inserting the oxygen supply tube. The transparent mask allows the operator to immediately see any strange objects that may be regurgitated during resuscitation. The softness of the cushion guarantees the perfect adhesion to the patient's face. Flex Mask is a must have for every first aid kit and above all pocket! Flex Mask, as well as being a live saving instrument, can also be used on training mannequins.
