oxygen respirator

Prahd was going around to the last of the officers now, applying an oxygen respirator to their faces.

Then he put out a call to every boat within twenty miles to come quickly with any piece of resuscitating equipment and oxygen respirator they had on board.

A smoky, fast-moving fire erupted near an oxygen respirator at Beekman-Downtown Hospital in lower Manhattan yesterday, killing a 26-year-old AIDS patient as he lay in his bed.

He is kidnapped from his office that night and brought to an abandoned zoo, and awakens in a vise designed to tighten around his torso each time he breathes into an oxygen respirator.
