At the scene of an accident many years ago, I was able to help a young woman who had been hit by a car. She had hit her head, fallen to the ground and began to have a seizure. I called 911 right away, and I shouted, “Clear the air!” when too many people began to crowd around. When people attempted to put something under her head and others said, “Put something in her mouth to keep her from swallowing her tongue,” I was able to swiftly say they should leave her alone. I had learned to do these things in a one-day first aid seminar at my workplace.
