The vast increase in our industrial production since the outbreak of war has of necessity exposed a greatly increased number of workers, many of them inexperienced in the handling of industrial equipment, to hazards from toxic fumes. This unfortunate effect has been particularly reflected in the rise in incidence of pulmonary edema following exposure to toxic gases. Indeed, so frequently has pulmonary edema been noted as a terminal event in these cases that it seems desirable to call attention to a simple method which has proved effective in the prevention as well as the treatment of these cases.

Briefly, the method consists in absolute bed rest and the immediate administration of oxygen under atmospheric pressure with a provision for expiration against calibrated resistance of from 1 to 6 cm. of water pressure.

We begin at once the administration of 100 per cent oxygen under atmospheric pressure, setting the expiratory valve
