The transparent design of the Ambu Res-Cue Mask allows the rescuer to constantly visually check the patient conditions.

The mask is equipped with a head strap for a fixation of the mask onto the patients face. Thus the rescuer does not loose time for replacement of the mask before mouth to mask ventilation.

Thus an oxygen tube can be attached to the oxygen inlet for supplemental oxygen. It comes optionally with an oxygen inlet (optional) facilitates increased oxygen delivery*.
It is a reusable facemask that is easy to clean which extends the product life. 

The valve filter assembly is single use and has to be replaced after each use.
