The Hum resuscitation device is a PVC mask for use with a manual or automatic resuscitation bag. The transparent material allows the patient’s condition to be observed, while the soft cushion is inflated with air to fit the face. Its design makes it easy to handle by hand.

The mask has a size-coded color ring and an air inflation valve for adding or removing air so that it can be adjusted to the patient’s face.
