First Aid Essentials: Common Misconceptions and Updated Practices

Many believe alcohol disinfects wounds, but it can actually harm tissue and delay healing. Instead, run clean water over the injury to clean it and use mild antiseptic for disinfection.

CPR has evolved. 'Hands-Only CPR' with just chest compressions at 100-120 beats per minute is effective in emergencies for adults and teenagers, especially if you're untrained in rescue breaths.

Use the acronym FAST to identify strokes: Face drooping, Arm weakness, Speech difficulties, and Time to call emergency services. Quick response can significantly improve outcomes and reduce long-term disabilities.

Hypothermia can occur in temperatures above freezing, especially if a person becomes chilled from rain, sweat, or submersion in cold water. Warm the core first, not extremities, to prevent shock.

For burns, cooling the area immediately under cool running water for at least 20 minutes is crucial. It reduces tissue damage and pain. Don't apply ice directly as it can cause further damage.
