Overview
Brief Summary
Electrical impedance tomography (EIT) is an evolving monitoring tool for respiratory support in neonatal and pediatric intensive care. In this observational study basic EIT parameters will be measured on 20 healthy newborn infants during spontaneous breathing and assess the effect of position changes in ventilation distribution.
Detailed Description
NEO SensorBelts will be used to observe ventilation distribution in healthy newborn infants during quiet spontaneous breathing. Child's position will be changed 5 times every 10 minutes in a random order. Positions observed will be: left lateral, right lateral, supine, prone face to left, prone face to right and supine with the bed tilted 30 degrees. Total duration for the recording will be 1 hour.

Outcomes
Primary Outcomes
Right-to-left ventilation distribution
Time Frame: 1 hour
Changes in right-to-left ventilation distribution following position changes will be calculated
Anteroposterior ventilation distribution
Time Frame: 1 hour
The ventral-to-dorsal center of ventilation will be calculated as described in (Frerichs et al., Acta AnaesthesiolScand. 1998; 42:721-726) as a value between 0 and 100%, higher values indicating a more dorsal distribution of ventilation.
