What this Trial Is About
Researchers are studying lung volume changes in preterm infants receiving synchronized noninvasive positive pressure ventilation (sNIPPV) for respiratory distress syndrome and other lung conditions. This observational study aims to understand how synchronized breaths affect lung aeration compared to non-synchronized or backup inflations, using Electrical Impedance Tomography (EIT) to measure these effects. The goal is to clarify the intrapulmonary mechanisms behind sNIPPV's benefits in preventing respiratory failure. Participants will have an EIT belt and pulse oximeter sensor attached during a nursing care session. The study involves switching ventilation modes between sNIPPV and continuous positive airway pressure (CPAP) to record lung function during spontaneous, synchronized, non-synchronized, and backup breaths. Measurements are taken at multiple predefined timepoints over a 180-minute recording period, with ventilator settings held constant throughout. During the study, lung volume changes, regional aeration, heart rate, oxygen levels, and lung ultrasound scores will be continuously monitored and analyzed. The EIT device records lung impedance and ventilation distribution to assess breathing patterns. Data collection concludes after the next nursing session when sensors are removed. This process helps researchers evaluate how different ventilation modes impact lung function in very young preterm infants.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Approximately 1 nursing care session
Participants will have an Electrical Impedance Tomography (EIT) belt and a pulse oximeter sensor attached during the final nursing care session before the study begins.
1 visit (in-person)
Duration - 3 hours
Participants will be observed continuously while receiving synchronized noninvasive positive pressure ventilation (sNIPPV). Lung volume changes and respiratory parameters will be recorded over a 180-minute period including baseline spontaneous breathing periods using CPAP.
