Of course, this ought to be something that should be covered practically. Thus, ideally, this isn't something you can learn/practise by just reading. Unfortunately, even the school I went to covered just the theoretical aspects!

Here is the resource, by the National Health Portal of India. It covers:

• First Aid Box
• Heavy Bleeding
• Head Injury
• Burns
• Unconsciousness
• Heart Attack
• Nose Bleeding
• Snake Bite

PS: Even a healthy heart can stop suddenly - known as sudden cardiac arrest. Death can be prevented if a CPR is performed. Some 700,000 people die due to sudden cardiac arrests [each year]. With a population of 1.4 billion, and a lifespan of 80 years, that translates to a 4% chance that you'd die due to a sudden cardiac arrest, if someone around you does not know CPR!

If you think there are topics in first aid that are not covered, let us know.
