About this trial

This is an interventional treatment trial for Infant, Premature, Diseases focused on measuring CPAP, Bronchopulmonary Dysplasia, Ventilator Induced Lung Injury, V/Q mismatch

Eligibility Criteria

24 Hours - 35 Weeks (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Born at 27-35 weeks gestational age (GA) by best obstetric estimate, determined by the clinical obstetric team during antepartum admission.
  2. Age limits: 24 hours of age - 35 weeks corrected gestational age.
  3. On continuous CPAP support between 4-8 cm H2O for greater than 24 hours, as document on the bedside infant flow sheet.
  4. Supplemental oxygen requirement, with a fraction of inspired oxygen (FiO2) 0.25 for at least 2 consecutive hours, as documented on the bedside infant flow sheet.

Exclusion Criteria:

  1. Congenital anomalies, as determined by the clinical supervising physician.
  2. Current or prior air leak syndrome, as determined by the clinical supervising physician.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Continuous positive airway pressure (CPAP) level changes

Arm Description

Protocol guided changes in CPAP level from clinical baseline, with responsiveness in V/Q mismatch guiding subsequent changes; limited to a range of -2 to +3 cm H2O from baseline

Outcomes

Primary Outcome Measures

Ventilation/Perfusion Mismatch
Measured by non-invasive computerized technique based on curvilinear characteristics generated by a best-fit curve connecting the fractional inspired oxygen and corresponding peripheral oxygen saturation pairs; measured as difference in degree of right-shift between baseline and "best" CPAP

Secondary Outcome Measures

Best CPAP Level
Defined as the lowest CPAP level associated with an improvement greater than 5% in V/Q mismatch relative to the preceding CPAP level

5. Study Description

Brief Summary
Continuous positive airway pressure (CPAP) is used in premature infants to maintain lungs open and facilitate gas exchange. When ventilation/perfusion (V/Q) mismatch is present, areas of the lung that are open for gas exchange do not match up with the areas of the lung that are receiving blood for gas exchange. This study measure the responsiveness of V/Q mismatch to changes in the amount (or level) of CPAP.
