🔍 Quick Summary
An asthma attack in a child happens when the airways suddenly become much narrower, making it difficult to breathe.
Some attacks are mild and improve with the correct treatment, while others can quickly become life-threatening.
👉 Knowing the warning signs and acting early can save your child's life.
🚨 If this is happening right now
• keep your child sitting upright
• help them use their reliever inhaler with a spacer if prescribed
• stay calm and reassure your child
• if breathing does not improve quickly or symptoms are severe, call your local emergency services immediately
👉 Early treatment can prevent serious complications.
1️⃣ What is happening?
During an asthma attack, the small airways inside your child's lungs become much narrower.
This happens because:
• the lining of the airways becomes swollen
• the muscles around the airways tighten
• extra mucus blocks the air passages
Because less air can move in and out of the lungs, breathing becomes difficult.
👉 Children can become seriously unwell more quickly than adults, so early recognition is important.
2️⃣ Warning signs 🚨
Early warning signs
• coughing, especially at night
• wheezing (a whistling sound when breathing)
• shortness of breath
• chest tightness
• becoming tired during play
• asking to be carried more than usual
Danger signs
• breathing very fast
• unable to finish sentences
• chest pulling in between the ribs or below the neck (retractions)
• nostrils flaring with each breath
• blue or grey lips or fingertips
• becoming unusually quiet, sleepy or confused
• little or no wheezing despite severe breathing difficulty ("silent chest")
👉 Children may not always tell you they are struggling to breathe. Changes in their behaviour can sometimes be the first warning sign.
3️⃣ What should you do immediately?
• keep your child sitting upright
• stay calm and reassure them
• give the reliever inhaler exactly as instructed in your child's asthma action plan
• always use a spacer if one has been prescribed
• continue watching your child's breathing closely
• call emergency services immediately if symptoms do not improve or become worse
👉 Acting early gives treatment the best chance to work.
4️⃣ What should you NOT do?
• do not make your child lie flat
• do not delay treatment while hoping symptoms will pass
• do not rely only on home remedies
• do not force your child to eat or drink if they are struggling to breathe
• do not leave your child alone during a severe asthma attack
👉 Delaying treatment can allow the attack to become more severe.
5️⃣ When should you call emergency services? 🚑
Call emergency services immediately if your child:
• cannot speak or cry because of breathlessness
• is struggling to breathe even after using the reliever inhaler
• has blue or grey lips or fingertips
• has severe chest pulling in with each breath
• becomes drowsy, confused or difficult to wake
• has a "silent chest" with very little air movement
• collapses or loses consciousness
👉 Never wait if your child's breathing is getting worse.
6️⃣ What happens at the hospital?
Your child may receive:
• oxygen
• repeated reliever medicines
• steroid medicine to reduce airway inflammation
• close monitoring of breathing and oxygen levels
• admission to hospital if symptoms remain severe
👉 Most children recover well when treatment starts early.
7️⃣ Recovery
After an asthma attack:
• your child should be reviewed by their healthcare professional
• medicines may need adjusting
• inhaler technique should be checked
• the asthma action plan should be updated if necessary
👉 An asthma attack is an opportunity to improve long-term asthma control.
🟢 Important Message
Most childhood asthma attacks can be treated successfully, especially when recognised early.
👉 Never ignore worsening breathing or unusual tiredness in a child with asthma.
FAQ
• Can a child have an asthma attack without wheezing?
Yes. Some children, especially during severe attacks, may have very little wheezing because very little air is moving through the lungs.
• Should I always use a spacer with the inhaler?
Yes, if your healthcare professional has recommended one. A spacer helps more medicine reach the lungs.
• Can my child sleep after an asthma attack?
Only if their breathing has improved and your healthcare professional has advised it is safe. If symptoms continue or worsen, seek urgent medical care.
• Can colds trigger asthma attacks in children?
Yes. Viral infections such as the common cold are one of the most common asthma triggers in children.
• Does one asthma attack mean my child's asthma treatment should be reviewed?
Usually, yes. A review helps ensure the treatment plan and medicines are still appropriate.
🧠 Why We Delay
Parents often think their child only has a bad cold or that the wheezing will settle on its own.
Others may worry about overreacting or hope that another dose of the reliever inhaler will solve the problem.
Unfortunately, children's breathing can worsen quickly during an asthma attack.
👉 Seeking help early is much safer than waiting until your child becomes severely breathless.
