A theory of warmth became a resuscitation device

In the eighteenth century, rescuers faced a frightening problem: someone pulled from the water could be unconscious and not breathing, with no reliable way to restart the process. Doctors thought warmth and bodily stimulation might help revive the person. Tobacco smoke seemed to offer both, so they tried delivering it through the rectum—an approach then used in other medical treatments as well.

The idea became a piece of equipment. Bellows pushed air through burning tobacco and into a tube, which was inserted into the patient. The apparatus made the treatment seem controlled and practical, but it could not fix the central problem: drowning prevents the lungs from supplying the body with oxygen.

Why the treatment could not do what rescuers needed

Smoke in the rectum could not restore the flow of air into the lungs. Even if the tobacco caused irritation or warmth, those sensations were not the same as restarting breathing or delivering oxygen to the brain and other organs. The device turned a plausible-sounding theory into a repeatable procedure without making it effective.

That distinction matters in the history of medicine: a treatment can look purposeful, use specialized equipment, and still miss the bodily process that needs to be restored. The bellows had a clear job—pump smoke—but the person needed air in the lungs.
