DRSABC action plan or flow
1. DANGER - check first the danger and source of injury
2. RESPONSIVENESS - Can the casualty hear your voice? Can they open and close their eyes? Are there any movements? Do they respond to touch?
3. SEND - send for help or shout for help
4. AIRWAY - is the person's airway clear? If the person is not responding and is unconscious, check airway by opening the mouth and having a look inside. Tilting the head back with the chin facing up will clear an airway.
5. BREATHING - make sure that the victim is breathing by looking at breathing signs, listening to exhales, and feeling air coming out of the mouth or nose.
6. CPR (cardiopulmonary resuscitation) - if an adult is unconscious, no pulse, and not breathing, perform the CPR until the emergency personnel or medics arrive.
