I’ll top that with another story. I used to work in respiratory therapy in a surgical ICU and took care of many patients on ventilators post-surgery and weaning them off the device to where they could breathe unassisted and go home.
We had a gentleman come from the nursing home, who due to smoking all his life was on a ventilator permanently, hooked to a tracheostomy in his throat. When he was stable, the nurses in the home could monitor him but when he began to worsen he would be shuttled to the hospital for extra care.
When a ventilator becomes unhooked or a line becomes blocked one or more alarms go off, and regularly alarms would come from his room. By the time I walked in, the alarms would stop, and I would find everything in order. Then a following night I found out the source of the alarms. I came into the ICU with the alarms going off in his room, and entered to find the man had removed the machine that was breathing for him, and had retrieved a secret stash of cigarettes, and was in the act of lighting and smoking one by sticking it into the tracheostomy hole in his throat.
The nurses called him the Marlboro Man.
