📘 Lesson Summary

Asthma is a common condition that affects the airways, making it difficult to breathe.

During an asthma attack, the airways become narrowed, inflamed and filled with mucus, which can quickly become life-threatening if not treated.


⭐ What is Asthma?

Asthma causes the airways to:

  • Tighten
  • Become inflamed
  • Produce excess mucus

This makes it harder for air to move in and out of the lungs.


⚠️ Recognition of an Asthma Attack

  • Difficulty breathing
  • Wheezing (whistling sound when breathing)
  • Persistent coughing
  • Shortness of breath
  • Tightness in the chest
  • Difficulty speaking full sentences
  • Anxiety or distress
  • Blue lips in severe cases

🩺 Treatment

  • Sit the casualty upright
  • Stay calm and reassure them
  • Help them use their reliever inhaler (usually blue)


👉 Up to 10 puffs can be given if needed


🚨 Call 999/112 if:

  • There is no improvement after 10 puffs
  • The inhaler is not available
  • The casualty is getting worse
  • They are too breathless to speak or eat
  • Lips turn blue
  • You are unsure

⚠️ Important

  • Continue giving one puff every 30–60 seconds until help arrives
  • Do not leave the casualty alone
  • Always monitor breathing

💡 Key Takeaways

  • Asthma attacks can become life-threatening quickly
  • Sit the casualty upright and keep them calm
  • Use a reliever inhaler immediately
  • Call emergency services if symptoms do not improve
