Amen! Great point. The world has lost a fair share of hippies to wood stoves in buses. You go off grid and all the sudden you got all this stuff generating CO2: propane fired everything, kerosene lamps, wood or pellet, stoves. A couple guys I knew of tried to recover heat from the water heater in their RV and died that same night. This might apply even more to newer RVs with sound gaskets and tight windows.

Whoops! Caught an important error in the treatment of CO2 poisoning and it's a biggie. If the person is unresponsive or not breathing, begin VENTILATING them without the chest compressions. If the person is not breathing regularly get them on their back, open their airway and elevate their legs. If you have O2 use it. We don't perform CPR on a conscious patient and we don't perform chest compressions unless the person has no pulse. CPR involves bone breaking levels of force.
