While on a routine dialysis pick up at a nursing home, a 911call was going on at the same time. As the crew passed by us one guy was doing very light one handed compressions on a smallish 80+y/o F. They were not using a bvm or any O2 for that matter. Nor was there an AED or monitor hooked up. Any clue as to why they were performing CPR like this? The squad is the largest and one of the most respected in the county, so its not like it was sketchy fly by night transport company that didn't know what they were doing. Thoughts?
