Description of intervention(s) / exposure
In infants with Congenital Diaphragmatic hernia, we will observe the differences in lung ventilation in different positions.
The exposure will be the routine position changes, such as, supine, quarter turn from supine or side lie. Infants are normally positioned approximately every 6 hours. EIT and Physiological data will be collected after routine position changes - immediately, at 30 minutes, 1 hour, 2 hours and 6 hours after each position change. Recordings will continue for a total of 24 hours.
Participants will receive routine position changes regardless of their involvement in this study.

Statistical methods / analysis
The Mater Mothers Hospital receives on average, 30 CDH patients per year. As such, over a 4-month period, we expect a sample size of 10 infants.
Results will be presented as mean and standard deviation (SD) for the demographic and baseline clinical data. Generalised estimating equations will be used to determine differences and interactions between positions for each dependent variable. A p-value of < 0.05 will be considered statistically significant. All statistical analyses will be performed using SPSS (v26.0, Lead Technologies, Inc., Chicago, IL, USA).

Summary
Brief summary
Congenital diaphragmatic hernia (CDH) is a condition requiring immediate medical and multidisciplinary management, including physiotherapy. Positioning is a commonly used physiotherapy technique supported by the literature. However, the extent of its improvement on the respiratory system is unknown due to the limitations of the measuring equipment. Current measuring tools lack the ability to detect regional changes in the lungs. Electrical impedance tomography (EIT) has shown to be safe and effective in other areas of the healthcare system but has not been used for infants with CDH. This study will use EIT to assess the effectiveness of positioning in infants with CDH.
