First aid serves both purposes mentioned:
a) **To save from danger to life**: First aid includes immediate actions taken to preserve life, prevent the condition from worsening, and promote recovery. Techniques such as CPR (Cardiopulmonary Resuscitation), controlling bleeding, and stabilizing injuries are crucial in saving lives during emergencies.
b) **To clean wound**: Cleaning and dressing wounds is also a fundamental aspect of first aid. It helps prevent infection, promotes healing, and reduces the risk of complications. Proper wound care involves cleaning the wound with antiseptic solutions, removing debris, and applying appropriate dressings.
Therefore, first aid encompasses a range of actions aimed at both saving lives and addressing immediate health concerns, including wound care.
