Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Infants under 30 weeks gestation who require respiratory support at birth will receive positive pressure delivered by gases (oxygen and air) that are heated and humidified using a heated humidifier unit. Infants requiring ongoing respiratory support will continue to receive heated and humidified gases during transport to the neonatal intensive and special care unit (NISC).
The intervention will be given for the duration of the stabilisation in the delivery room and transport from the delivery room to the NISC. This will differ on a case by case basis and be directed by the attending clinican.

Treatment: Other
Comparator / control treatment
Infants under 30 weeks gestation who require respiratory support at birth will receive positive pressure delivered by unconditioned gases (oxygen and air) which is the current standard care. Infants requiring ongoing respiratory support will continue to receive unconditioned gases (oxygen and air) during transport to the neonatal intensive and special care unit (NISC).
The standard care treatment will be given for the duration of the stabilisation in the delivery room and transport from the delivery room to the NISC. This will differ on a case by case basis and be directed by the attending clinican.
