Bronchiolitis is a common viral infection that makes breathing difficult in young children. When your baby is hospitalised with this condition, doctors may offer two types of breathing support: high-flow nasal cannula (HFNC), which delivers oxygen through small tubes in the nose, or continuous positive airway pressure (CPAP), which uses gentle air pressure to keep airways open. A new review of 10 studies involving nearly 1,000 children compared these two methods to see which works better.
Researchers from multiple countries examined whether either method was more effective at helping children recover and preventing the need for stronger breathing machines.
Both methods work equally well, but HFNC is gentler
The key finding: both HFNC and CPAP are equally effective at treating bronchiolitis. Neither one is significantly better at preventing treatment failure or reducing the need for more intensive support. However, there is one important difference. Children using HFNC experienced noticeably fewer side effects, including less nasal irritation, skin breakdown, and general discomfort. Since your child is already struggling to breathe and feeling unwell, comfort during treatment matters considerably for their recovery and your peace of mind during a stressful hospital stay.
Age and weight may influence which method suits your baby best
The research suggests HFNC may be especially suitable for babies older than 3 months and weighing more than 6 kg. For very young or smaller infants, both methods appear to work equally well with similar comfort levels. This means your doctor can tailor the choice based on your individual child's characteristics rather than a one-size-fits-all approach.
Ask your doctor about HFNC as a starting point
- Request HFNC first if your baby is over 3 months old, since it causes fewer side effects while remaining equally effective.
- Watch for nasal redness, skin irritation, or signs of distress with either method, and report these immediately to your medical team.
- Remember both options are safe and effective—if your doctor recommends CPAP instead, it will still help your child recover well.
