Abstract: A pack worn by a rescuer holds an assembled resuscitation facemask. The pack has a pouch and has a flap and belt attached to the pouch. A face portion of the mask fits into an opening in the pouch. Preferably, a cutaway along the edge of the opening accommodates the projecting mouthpiece of the facemask. The flap closes over the mask in the opening, and an edge of the flap fastens to the pouch. The flap defines a cutout for the mouthpiece to project from the flap. Preferably, the cutout in the flap connects with a split defined in an edge of the flap. The split is smaller than the cutout such that first and second portions of the flap fit around the projecting mouthpiece when the flap is closed and fastened to the pouch.
