Carbon dioxide inhaled in high concentrations can be an anesthetic. When retained in the body as the result of severe lung disease, it can result in CO2 narcosis, coma, and death.
Carbon dioxide anesthesia was used in obstetrics and other surgery in the fifties, and is now used in pigs prior to slaughter. More humane than electroshock.
General anesthesia by a non-anesthesiologist and without proper monitoring and backup is a risky business, indeed.
thanks. Your post beat me to it.
I’ve heard of patients whose psychologist found “repressed memories” of abuse, but the carbon dioxide is a new one to me.
