W: Hi, Mike! I heard that you helped save people in an accident.
M: Yes. It was a nose-to-tail car accident, and it was really terrible.
W: Oh, my gosh! I bet there must be someone bleeding.
M: Yeah. The back car was seriously damaged and the front car was completely damaged at the back.
W: That’s terrible. I can imagine the scene. So you gave those injured people first aid. You are always so kind-hearted.
M: I was terrified at first, but I realized that we must take them to the nearest hospital as soon as possible. So I asked an on-looker to call the ambulance for help, and I just gave a bleeding man first aid.
W: How did you do that since the scene was so terrifying?
M: I put his head on the higher position to stop bleeding from his nose, and then I asked others to give those shocked passengers some drinks to ease their minds.
W: You were like the savior to them.
M: In a few minutes, all the injured people were sent to the hospital. It was really an emergency!
W: Yes! Quite an emergency! But thanks to the first aid you gave them. I think you are very good at it.
M: Yes, I was trained to give first aid several years ago and learned some basic skills about it.
W: Besides some injured people in a car accident, who should be given first aid?
M: Some people who have been injured or are in physiological distress due to choking, a heart attack, allergic reactions, drugs or other medical emergencies.
W: Oh, I see. What is the function of first aid?
M: Well, basic first aid allows you to quickly determine a person’s physical condition and the correct course of treatment.
W: Today, I see the importance of first aid. That’s really critical to the injured.
M: Yes, following correct first aid procedures can be the difference between life and death.
