In an emergency when any child or adult becomes suddenly unresponsive, the victim can be helped if those in close vicinity know Basic Life Support skills.
This can be easily practised with bare hands without any need for medical equipment. No definitive statistical data is available on awareness among high schoolers of basic life support (BLS) skill and their ability to use them when required. Training modules of different organisations are available for laypersons/high school students which can be inculcated in school curriculums without any extra resources.
I am a volunteer in these training modules. Training the teenager has a massive impact on the society as through them it percolated to their siblings and to their families which will being a change in the whole community.
