Rescue swimming

Rescue swimming is the body of skills that enable an individual to attempt a rescue when a swimmer is in difficulty. These include a combination of communication skills, specific "rescue" swimming strokes, and release and evade techniques for self-preservation should the rescue go wrong.
 * From the outset once a swimmer in difficulty is spotted, eye contact must be maintained at all times.
 * Assess the situation: environment, available physical equipment, others who can help, etc.
 * Attempt to establish voice contact, which if successful can often result in a "voice-rescue".
 * A rescuer should enter the water only as a last resort.
 * Rescues should be attempted in the following order: talk, throw, reach, wade, row, swim, tow and carry.

There are four main rescue strokes: front crawl, breaststroke, inverted breaststroke, and sidestroke.
