Seriously - walls are removed or doors removed, the frame cut out and the opening widened to get these super obese people out. Additionally, and I'm not kidding, they have used forklifts more than once after removing an exterior wall on second floor and higher. The fire departments do all this and we pay for it.
I was an ambulance driver in the 70's and you would not believe how many calls we went on where breathing and/or cardiac problems required the hugely obese to be transported to an ER. Then worked ER for 17 years as a med professional and been in medicine still (OR, ICU/CCU) going on my 4th decade.
Obesity should be immediately made a top priority national health issue with treatments deployed, beer and tobacco made prescription only and marijuana made 100% legal. We spend more health dollars on older patients in the last few years of their life than the rest of their life combined. A huge part of the care is centered on problems directly related to tobacco smoking (or oral cancer from smokeless like snuff) and alcohol. If not the primary cause they are very often an aggravating factor in major ways. Yet to see a single one due to marijuana use or even have that suggested by the most cynical doctor.
In ER we commonly saw marijuana "overdose" (on the chart form) which was always due to a new user just freaking out or to even veterans getting a big bud of killer sativa that robs your sense of balance and reality. No problem handling it and cheap too. Double strength coffee or anything with high dose caffeine kills a high fairly quickly. Jolt Cola was in every ER medicine fridge all the years they made it.
