Final answer:
Escaping anesthetic gas may be caused by factors such as the mode of administration, deep water diving, and choice of anesthetic compounds.
Step-by-step explanation:
Escaping anesthetic gas may be caused by factors such as the mode of administration, ascent from deep water diving, and the choice of anesthetic compounds. Inhalational anesthetics can be administered as gases or volatile liquids, and are usually delivered using an anesthesia machine. When divers ascend too rapidly from deep water, the decreasing ambient pressure can cause dissolved gases in their blood to escape and form bubbles, leading to decompression sickness (DCS). Finally, some anesthetic compounds, such as diethyl ether, have safety concerns for operating room personnel exposed to them.
