Meet the team behind the CIRCA DIEM study.

A sub-study is an ‘add-on’ study that helps to answer specific questions within a larger research project. If you decide to participate in the CIRCA DIEM study, you or your child may be invited to take part in one of the CIRCA DIEM sub-studies.

Neonatal high-frequency oscillatory ventilation: where are we now?High-frequency oscillatory ventilation (HFOV) is an established mode of respiratory support in the neonatal intensive care unit. Large clinical trial data is based on first intention use in preterm infants with acute respiratory distress syndrome. Clinical practice has evolved from this narrow population. HFOV is most often reserved for term and preterm infants with severe, and often complex, respiratory failure not responding to conventional modalities of respiratory support.


The CIRCA DIEM Study is a multicentre study, involving several different hospital sites across Australia. Here, you can find out more about which hospitals recruit babies into the CIRCA DIEM Study.

Respiratory and chest wall mechanics in very preterm infantsData on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung and Ccw to determine their relative contribution to static compliance of the respiratory system in very preterm infants at 36 wk postmenstrual age. We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia and impacted breathing variables.

Continuous Telemetric In Utero Tracheal Pressure Measurements in Fetal LambsNormal in utero lung development and growth rely upon the expansion of airspaces and the controlled efflux of lung liquid into the amniotic space. Infants with congenital diaphragmatic hernia (CDH) also have lung hypoplasia due to occupation of the chest cavity by the stomach and bowel and, in the most severe cases, the liver. Balloon tracheal occlusion reduces the severity of lung hypoplasia in fetuses with CDH but increases the risk of premature birth.
