      Basic first aid: heat imbalances, choking and anaphylaxis

      Lesson details

      Learning outcome

      I can explain how to help casualties suffering from heat imbalances, choking and anaphylaxis.

      Key learning points

      1. Heat imbalances include conditions like heat exhaustion and heat stroke.
      2. Cold water shock can be life-threatening and requires immediate action.
      3. Choking requires quick and effective first aid to clear the airway.
      4. Anaphylaxis is a severe allergic reaction that needs urgent treatment with an adrenaline auto-injector.

      Keywords

      • Heat imbalance - a condition where the body cannot regulate its temperature properly, leading to heat exhaustion or heat stroke

      • Cold water shock - a sudden and dangerous reaction of the body to cold water, causing muscle paralysis and difficulty breathing

      • Choking - a blockage of the airway that prevents normal breathing

      • Anaphylaxis - a severe allergic reaction that can cause breathing difficulties

      • Adrenaline auto-injector - a device used to deliver a dose of adrenaline to treat anaphylaxis

      Common misconception

      Cold water shock is only dangerous in very cold water.

      Cold water shock can occur in any temperature below 15°C.

      Teacher tip

      Referencing local bodies of water that could be dangerous could be helpful to contextualise the learning.
