[00:00.00]Exercise 2.2
[00:10.82]Today, we will talk about choking 1.
[00:13.67]In fact, choking is quite a common problem
[00:17.08]in our daily life.
[00:19.29]What's choking?
[00:21.42]This is when someone has an object stuck in
[00:24.98]his or her throat.
[00:27.32]This happens quite often when people are eating
[00:31.48]If a piece of food gets stuck,
[00:34.22]the person can't breathe
[00:36.46]and the food doesn't go down.
[00:39.30]When this happens,
[00:40.80]we say that the person is choking.
[00:44.33]Everyone should know what to do.
[00:46.88]What should we do when this happens?
[00:49.47]Should we hit the person on the back?
[00:52.10]No, you shouldn't do that.
[00:54.12]That's not a good idea because that can make
[00:57.93]the object move down and maybe get stuck more.
[01:02.55]You should do a trick called
[01:04.28]the Heimlich Maneuver 2.
[01:05.94]What's that?
[01:07.37]It's a special movement to help a person
[01:10.17]who is choking.
[01:12.07]It's called the Heimlich Maneuver after Doctor
[01:15.48]Henry Heimlich,the man who invented it.
