Spencer Flex Mask is used for resuscitation without any need of mouth to mouth contact. It comprises of one-way valve connected to a transparent resuscitation mask. This helps the operator to immediately see any strange objects that may be regurgitated during resuscitation. Also, during the process of resuscitation, the air flow can be enhanced with oxygen by removing the cap on the mask and by inserting the oxygen supply tube. It can be used any time to resuscitate a patient in situation of respiratory arrest. With its unique lifesaving usefulness, Flex Mask is a must have for every first aid kit.
