简要总结
This is a prospective, observational cohort study. For the study part on noninvasive neurally adjusted ventilatory assist (NIV-NAVA) the design is interventional. For all participants prospective data collection will be conducted by chart review and by downloading ventilatory data from the ventilator. A registration of respiratory severity score will be done by a caregiver during the weaning period. This consists of a visual assessment of the work of breathing every 2 hours. For participants on NIV-NAVA consenting to the interventional part of the study a titration procedure will be conducted, afterwards serial electrical impedance tomography and lung and diaphragm ultrasound measurements will be done.

入选标准
- •Preterm infants (< 37 weeks GA) supported with non-invasive respiratory support for at least 24 hours. Non-invasive respiratory support can consist of non-invasive NAVA, nasal continuous positive airway pressure (nCPAP) or high flow nasal canula (flow > 2 liters/min).The support can be given as primary respiratory support or as respiratory support after weaning from invasive ventilation (= after extubation).
- •Infants can only be enrolled after written and signed informed consent by the parents.
排除标准
- •Infant born after a gestational age of 37 weeks or more.
- •Infants with major congenital malformations or chromosomal abnormalities (eg trisomy 18, congenital diaphragmatic hernia…)
