1 Do NOT remove an object such as a knife, stick, or arrow that is stuck in the body. Doing so may cause more damage and bleeding. Place pads and bandages around the object and tape the object in place.  Put pressure directly on an outer wound with a sterile bandage, clean cloth, or even a piece of clothing.
Carbon Monoxide is always lighter than air down to 32 degrees. Plus it come out of the appliance hot which would put it at the ceiling first. Warmest air in the room is at the ceiling therefore it would linger there the longest.
Carbon Monoxide, when in the body, takes the place of oxygen. It affects. hemoglobin, which carries oxygen in the red blood cells. Hemoglobin is an iron molecule that is complexed. The carbon monoxide complexes the iron limiting its oxygen carrying capability. This causes brain damage and the body to slow down and suffocation.
