[00:04.00]may simply be that the airway is blocked…
[00:06.53]they've swallowed their tongue,
[00:08.05]as you might say and so very often
[00:10.88]all that's needed is to open up the airway.
[00:14.21]This is actually very simple-
[00:16.54]you just place two fingers beneath the chin,
[00:19.46]and use them to lift the head back,
[00:21.93]and that will be enough
[00:23.10]to straighten up the airway.
[00:25.53]You may well actually hear a deep
[00:27.55]intake of breath when this happens.
[00:30.21]But if you aren't sure whether or not
[00:31.80]they are breathing,then put your ear
[00:34.07]close to their mouth,and you will probably
[00:36.44]be able to feel their breath ticking your ear,
[00:39.11]and then you know it's okay.
[00:42.29]If the patient still isn't breathing,
[00:45.12]you need to start mouth-to-mouth resuscitation
[00:47.07]at this point.
[00:49.07]To do this,you pinch their nostrils together
[00:51.85]hard,with one hand,and hold their chin with the
[00:55.01]other hand so that their head is tilted back.
[00:58.74]Then you need to cover their mouth with your
[01:01.48]mouth…this is really important.
[01:04.18]You need to completely seal their mouth so that
[01:06.99]no air can escape-
[01:08.45]that's why you're pinching their nose.
[01:11.28]Then you press down hard,
[01:13.13]and breathe into their mouth,
[01:15.31]watching out of the corner of your eye tosee
[01:15.31]
