Brief Title

Seattle-PAP Bubble Nasal CPAP and Work of Breathing

Official Title

A Study to Evaluate the Efficacy of Seattle-PAP for the Respiratory Support of Premature Infants

Brief Summary

      The investigators propose to test the hypothesis that Seattle bubble nasal continuous
      positive airway pressure (Seattle-PAP) supports respiratory physiology in very low birth
      weight (VLBW) infants more effectively than standard bubble nasal continuous positive airway
      pressure.

Detailed Description

      The primary outcome variable is work of breathing (WOB) over a two hour period, estimated
      from pressure-rate products, which are assessed with 6 Fr (2 mm) catheters placed in the
      distal esophagus for monitoring esophageal pressures (Pes), thereby estimating changes in
      pleural pressures during breath cycles. The following endpoints would also be assessed:
      Oxygen saturations and Fraction of Inspired Oxygen (FiO2) needed to keep saturations in
      acceptable ranges, Heart Rates (HR), transcutaneous carbon dioxide (TcPCO2), and respiratory
      rates throughout the 6 hour study period.

      Objective determination of when an infant requires more or less respiratory support is
      difficult, but measurements of pressure-rate products as estimates of work of breathing,
      using esophageal catheters, can estimate an infant's respiratory effort. However, objective,
      simple-to-use, low cost, and non-invasive methods and tools to determine an infant's
      respiratory effort do not exist currently.

      This study also is designed to test the hypothesis that infants' chest and abdominal
      movements can be assessed quantitatively from video images in ways that can be correlated
      with intrathoracic pressures, as measured with esophageal catheters.
