First recorded in 1915–20

A nurse was near by with a tray of hypodermics and an oxygen mask.

He let go of the controls, adjusted his oxygen mask and sucked the life giving gas into his lungs.

In the excitement his oxygen mask had slipped down off his face and he could not reach the tube with his lips.

His oxygen mask was still in place, but his helmet hung partly loose.

He struggled to his feet, jerked an oxygen mask from the bag at his chest, clamped it to his face and rushed to the tubes.
