Breathing air study for bronchiolitis and obstructive bronchitis

We are investigating whether substances in the exhaled air of young children can help predict how long a child will need to stay in hospital when being treated for obstructive bronchitis or bronchiolitis. This examination is non-invasive and painless; the child simply exhales into a disposable collector (a type of balloon) developed for this purpose.

Children aged 0 to 3 years who are hospitalised at UKBB due to obstructive bronchitis or bronchiolitis.

Your participation helps us to better understand lung diseases in young children, to recognise early signs of more severe courses and to prepare future studies and treatments.

None.

All data will be treated confidentially.
Upon participation, the study team receives access to the clinical data recorded in the hospital system that is relevant to the study, which is treated confidentially in accordance with the law and immediately pseudonymised. There is no direct medical benefit for the individual patient.

• Information provided by the study team and signature to consent to participation.
• Daily, simple breath samples during hospitalisation (approx. 1 minute, in the patient's room, inflation of the balloon).
• A short questionnaire for parents.

Participation period: 2025-2026 in the respective patient room at UKBB.

You or your child can withdraw from participation at any time without giving reasons.

Please note that your data will be registered when contact is established. If you are not interested in participating in a study, your data will be deleted immediately. Further information about our research: www.sinueslab.ch
