CPR Drowning and Water Emergency Resuscitation 2 — Questions and Answers
Question 1: What does the phrase 'no one is dead until they are warm and dead' mean in the context of drowning?
- Victims should be warmed before CPR can begin
- Cold-water drowning victims may survive prolonged submersion due to hypothermic protection (Correct answer)
- CPR should stop once the victim's body temperature drops below 30°C
- Drowning victims should not receive defibrillation until rewarmed
Correct answer: Cold-water drowning victims may survive prolonged submersion due to hypothermic protection
Hypothermia can profoundly slow metabolism and protect the brain, meaning victims submerged in cold water may survive and recover even after extended submersion.
Question 2: Which cardiac rhythm is MOST commonly found in drowning victims when cardiac arrest occurs?
- Ventricular fibrillation
- Pulseless ventricular tachycardia
- Asystole or pulseless electrical activity (Correct answer)
- Atrial fibrillation
Correct answer: Asystole or pulseless electrical activity
Drowning-related arrest is hypoxic and typically presents as asystole or PEA rather than the shockable rhythms more common in primary cardiac arrest.
Question 3: A drowning victim is rescued from cold water and is breathing normally. What is the most appropriate next action?
- Place on their back, elevate legs, and monitor
- Move them to a warm environment, monitor closely, and seek medical evaluation (Correct answer)
- Administer CPR as a precaution
- Give the victim warm fluids to drink immediately
Correct answer: Move them to a warm environment, monitor closely, and seek medical evaluation
Even conscious drowning victims can deteriorate from pulmonary edema or hypothermia and must be kept warm, monitored, and evaluated by medical professionals.
Question 4: What is the primary cause of cardiac arrest in drowning victims?
- Hypothermia causing bradycardia and arrest
- Hypoxia due to inability to breathe (Correct answer)
- Ventricular fibrillation triggered by cold water contact
- Vagal reflex from sudden water immersion
Correct answer: Hypoxia due to inability to breathe
Drowning prevents breathing, leading to progressive hypoxia which ultimately causes cardiac arrest if the victim is not rescued and ventilated.
Question 5: How does cold water submersion generally affect the chances of survival and resuscitation efforts?
- Cold water dramatically worsens outcomes by causing immediate cardiac arrest
- Cold water can extend the survival window due to reduced metabolic demand (Correct answer)
- Cold water has no significant effect on survival outcomes
- Cold water causes irreversible brain damage faster than warm water
Correct answer: Cold water can extend the survival window due to reduced metabolic demand
Hypothermia decreases cellular oxygen demand, which can extend the time window for successful resuscitation, especially in children submerged in very cold water.
Question 6: Which of the following best describes 'secondary drowning' (also called dry drowning or delayed drowning)?
- A second submersion event that occurs after initial rescue
- Delayed respiratory distress or pulmonary edema after a submersion event (Correct answer)
- A type of near-drowning that only affects children
- Cardiac arrest occurring more than 24 hours after water rescue
Correct answer: Delayed respiratory distress or pulmonary edema after a submersion event
Secondary drowning refers to respiratory compromise that develops hours after a submersion event, caused by water in the lungs triggering inflammation or spasm.
Question 7: When should rescuers consider stopping resuscitation efforts for a drowning victim?
- After 5 minutes of CPR with no pulse
- Immediately if the victim was submerged for more than 10 minutes
- Only after rewarming (if hypothermic) and determining no response to resuscitation (Correct answer)
- As soon as a shockable rhythm is identified
Correct answer: Only after rewarming (if hypothermic) and determining no response to resuscitation
Resuscitation should continue until the victim is rewarmed and evaluated in a hospital setting, as hypothermia can mimic death; termination decisions are made by medical professionals.
