Canadian Lifesaving Manual: Life Safety & Water Rescue Vocabulary

A comprehensive vocabulary collection covering key life-saving terminology, drowning prevention techniques, first-aid treatments, and rescue stroke skills aimed at maximizing survival utility and harm reduction.

Canadian Swim to Survive® Standard

A foundational set of aquatic skills designed to maximize survival probability during an unexpected fall into deep water: roll into deep water, tread water for 1 minute, and swim 50 metres.

Self-rescue

The active steps an individual takes to extricate themselves from aquatic danger, preserving their own life and minimizing injury when unexpected emergencies arise.

The Rescue Process

A dynamic three-step framework comprising Recognize, Assess, and Act, continuously repeated to optimize rescue efficiency and minimize overall risk.

Ladder Approach

A risk-reduction strategy structuring rescue methods from lowest to highest risk (Talk, Throw, Reach, Wade, Row, Swim, Tow, Carry) to protect the rescuer while maximizing victim survival.

Rescuer's Checklist

A sequential action guide ensuring effective rescue execution: Hazards, Assists, Entries, Approaches, Reverse/Ready/Reassess, Talk/Tow/Carry, Removals, and Follow-up.

Distressed Swimmer

A swimmer in difficulty whose body position approaches vertical and makes little forward progress, but who remains conscious and capable of breathing, calling, or waving for assistance.

Drowning Victim

An individual unable to maintain floating or breathing support at the water surface, incapable of calling for help, and progressing rapidly toward submersion or unconsciousness.

Heat Escape Lessening Position (HELP)

A self-rescue posture that extends survival time in cold water by pressing the legs together, tucking them up, and clamping arms against the chest to protect high heat-loss areas.

Huddle Position

A group cold-water survival technique where two to four individuals press their chests together and interlock arms to conserve collective body heat and increase group survival probability.

Undertow

A backwash current created when incoming wave water returns seaward along the slope of a beach, capable of knocking bathers down and pulling them into deeper water.

Rip Current

A strong, concentrated seaward current formed when water accumulated near the shore flows back out through a break in the surfline or an underwater channel.

Hydraulic Current

A dangerous recirculating water current formed at the base downstream side of a low-head dam that traps swimmers and floating objects underwater.

Primary Assessment

The immediate first-aid evaluation designed to rapidly identify and treat life-threatening conditions by evaluating level of consciousness, Airway, Breathing, and severe external bleeding.

Secondary Assessment

A structured, non-life-threatening evaluation consisting of a head-to-toe physical examination, history gathering, and monitoring of vital signs to prevent secondary complications.

WARTS

A mnemonic summarizing key shock-management steps aimed at minimizing physiological collapse: Warmth, ABCs, Rest and assurance, Treatment of underlying cause, and Semi-prone (recovery) position.

Cardiopulmonary Resuscitation (CPR)

An emergency life-support procedure combining external chest compressions and ventilations to manually maintain systemic blood flow and oxygenation to vital organs.

Automated External Defibrillator (AED)

A portable electronic device that analyzes heart rhythm and delivers an electrical shock to terminate lethal arrhythmias, greatly increasing cardiac arrest survival rates.

Anaphylaxis

A rapid, severe, systemic allergic reaction that triggers airway constriction, facial swelling, severe shock, and potential respiratory collapse.

Hyperventilation

Respiration that is excessively rapid or deep, depleting carbon dioxide levels in the blood and potentially causing sudden loss of consciousness without warning.

Angina

Chest discomfort or pain caused by a temporary reduction in blood flow and oxygen supply to the heart muscle, serving as a warning sign of cardiovascular distress.

Heart Attack

A life-threatening medical emergency caused by severe blockage of blood flow to a portion of the heart muscle, leading to muscle tissue damage and potential cardiac arrest.

Cardiac Arrest

The sudden loss of functional cardiac mechanical activity, indicated by unresponsiveness and absent or abnormal breathing, requiring immediate CPR and defibrillation.

Stroke

A neurological emergency resulting from interrupted blood supply to a portion of the brain, leading to localized tissue damage, facial drooping, arm weakness, and speech impairment.

Concussion

A traumatic brain injury resulting from direct or indirect impact forces transmitted to the head, altering neurological function and requiring immediate removal from activity.

Hypothermia

A dangerous decline in core body temperature resulting from prolonged exposure to cold air or water, leading to loss of coordination, confusion, cardiac instability, and potential death.

Eggbeater Kick

A highly effective, alternating rotary leg kick that generates continuous propulsion and stable vertical support during water rescues and spinal injury transport.

Body Mass Index (BMI)

A standardized body composition metric calculated as weight in kilograms divided by height in metres squared ($\text{BMI} = \frac{\text{weight}}{\text{height}^2}$) to assess weight-related health risks.
