Mechanical ventilation increases human distress and the cost of hospitalization during a critical illness. While minimal consensus exists on predictors of weaning outcomes across samples, prior research suggests that respiratory parameters related to oxygenation and ventilation are likely correlates of weaning outcomes and that patients with enlarged abdomens may experience respiratory changes and a delay in complete weaning. The purpose of this study was to examine the effects of four positions on selected respiratory parameters in mechanically ventilated patients with large abdomens. The conceptual framework was the Weaning Continuum Model (Knebel et al, 1994). The convenience sample consisted of patients on mechanical ventilation who were breathing spontaneously and whose measure of abdominal girth fit the study criterion (target n=50). The design was quasi-experimental. Positions included a baseline pre-test position with the head of bed at 30 degrees, and three experimental positions with head of bed 45 degrees, head of bed 45 degrees in reverse trendelenberg, and head of bed at 90 degrees. After five minutes in each position, measures were taken of oxygen saturation, spontaneous tidal volume, spontaneous respiratory rate, spontaneous minute volume, and rapid shallow breathing index. Patients returned to baseline position after each set of measurements. Statistical analysis included Pearson correlations, ANOVA, and multiple regression. The results of the study may guide acute care nurses in optimal positioning of mechanically ventilated patients and may add to what nurses know about successfully weaning patients from mechanical ventilation.
