Chest indrawing in a child — what it means and what to do.

Chest indrawing is the single most useful sign a parent can recognise to tell apart a child who is breathing comfortably from a child who is in trouble. It is more reliable than counting breaths — and it is something you can see across the room.

What chest indrawing looks like.

With each breath in, you may see one or more of:

• The skin between the ribs being sucked inward.
• The skin just below the ribcage being sucked inward, sometimes deeply.
• The dip at the base of the neck (suprasternal notch) being pulled in.
• The skin above the collarbones (supraclavicular) being pulled in.
• In babies, the lower chest sinks in noticeably while the tummy pushes out — "see-saw" breathing.
• In babies, the head may bob slightly with each breath because the neck muscles are working.

You may also see:

• Nose flaring — the nostrils widen with each breath in.
• Pursed-lip breathing in older children, especially with wheezing.
• The child sitting up to breathe rather than lying flat.

Why chest indrawing happens.

Air normally moves easily into and out of the lungs. When the small airways are narrowed (such as in asthma, bronchiolitis or croup) or the lungs are stiff (such as in pneumonia or bronchiolitis with fluid build-up), the breathing muscles have to work harder to pull air in. The negative pressure inside the chest gets stronger — and because a child's chest wall is soft, that negative pressure pulls the soft tissue inward visibly.

Common causes.

• Asthma flare: wheeze, prolonged breathing out, indrawing. Often improves dramatically with a reliever inhaler — but if it does not, that is an emergency.
• Bronchiolitis (under 2 years): after a viral cold, with wheeze or crackles, poor feeding, and visible indrawing especially at night.
• Pneumonia: fever, fast breathing, indrawing, sometimes one-sided chest pain.
• Croup: a barking cough, noisy breathing in (stridor), and indrawing — usually a young child, often at night.
• Foreign body aspiration: sudden onset of cough, choking and noisy breathing, often one-sided. This is an emergency.
• Anaphylaxis / severe allergic reaction: swelling, hives, breathing difficulty after exposure to a trigger. This needs immediate emergency care.

Mild vs significant indrawing.

The distinction matters. Mild indrawing may be acceptable during a self-limiting illness; significant indrawing is not.

• Mild: visible only between the ribs, only during cough, with no other red flags, in a child who is alert, feeding, pink, and not distressed. Watch closely and reassess often.
• Significant: visible at rest, below the ribcage, with neck muscle use, with head bobbing in a baby, with any other red flag, in a child who looks unwell, sleepy, pale, or unable to feed. This is for in-person care.

What to do right now.

1. Stay calm. The child will sense your calm.
2. Position the child comfortably — usually sitting upright. Do not force them to lie flat.
3. If the child has known asthma and an action plan, give the reliever inhaler as instructed, with a spacer.
4. Look for the red flags listed above. If any are present, go to in-person pediatric emergency care immediately.
5. Do not give over-the-counter cough syrups or sedating medicines to a child who is indrawing significantly.
6. If unsure, in-person assessment is always the safer answer than waiting online.

When it is not an emergency.

Brief, mild indrawing during a cough fit in an otherwise well child can be acceptable as long as it settles quickly and there are no other red flags. Newborn babies may have mildly visible chest movement that is not true indrawing. When in doubt, in-person review is better than online review for indrawing concerns.
