Abstract:BackgroundThe breathing intolerance index (BITI) is used to evaluate respiratory muscle tolerance. The higher the ratio of the inspiratory time to the total breathing time and the ratio of the tidal volume to the vital capacity, the more easily the respiratory muscles become fatigued. The BITI is high with chronic respiratory failure, and values of 0.15 or more indicate the need for assisted ventilation.ObjectiveThis study aimed to examine the changes in the BITI of very low birth weight infants (VLBWIs) and d… Show more
