Clinical Trial Summary

To measure changes in physiologic parameters in extremely low birthweight (ELBW) infants on high-flow nasal cannula compared to nasal continuous positive airway pressure (nCPAP).

Description:

After informed consent is obtained, eligible infants who are stable on nCPAP therapy of 5-7 cm H20 achieved with a ventilator, an underwater "bubble" system, or a variable-flow device will be enrolled.

All subjects will have physiologic data and electrical impedance tomography collected at:

1. Baseline nCPAP for 15 minutes

2. Upon transition to high flow nasal cannula at 8 LPM for 6 hours. Data collection is obtained after infant is calm for 15 minutes at the beginning and end of this 6 hour period

3. Then upon return to baseline NCPAP for a final 15 minutes of data collection.
