First aid is the assistance given to any person suffering a sudden illness or injury, with care provided to preserve life, prevent the condition from worsening, or to promote recovery. It includes initial intervention in a critical situation prior to professional medical help being available. First aid can be performed by anyone with basic medical training, so it is important to learn these skills.
There are many different situations where first aid might be required, so it is important to be familiar with a wide range of techniques. Basic first aid skills include things like wound care, controlling bleeding, and managing shock. It is also important to know how to deal with common injuries such as burns, broken bones, and strains. First aid training can be provided by a variety of organizations, and it is often a good idea to take a course so that you are familiar with the latest techniques.
