A: Look, Jim. That man just fell down over there.

B: We‘d better see if he's o.k.

A: Sir…sir? Are you all right? Sir?

B: He's not answering. You'd better check his pulse and breathing.

A: Oh, no. He's not breathing, and there's no pulse. Call 911.

B: Hello? Yes. Someone has passed out at Connecticut Ave. and 2street St. He isn't breathing and does not have a pulse. Yes. My friend is performing CPR. OK. Thank you. They're sending an ambulance. Here, let me help.
