The case reported here is presented as an illustration of the usefulness of carbon dioxide-oxygen after an overdosage of morphine. Such application of carbon dioxide was suggested several years ago by me during the early period of my use of carbon dioxide-oxygen in the depressed states of ether anesthesia. The mixture of 10 per cent carbon dioxide and 90 per cent oxygen in an ordinary oxygen cylinder, with the so-called wash-bottle and tubing outfit, is now used extensively in hospitals for relief of respiratory failure of almost any source, such as surgical shock, anesthesia (during and after), cardiac conditions, pneumonia, carbon monoxide poisoning and morphine poisoning.
