Brief Summary

Lower lobe atelectasis of the lung is common in Acute Respiratory Distress Syndrome (ARDS) and has the potential to adversely impact lung compliance and intra-pulmonary shunt. The cephalic shift of the diaphragm and dorsal atelectasis associated with the commonly used supine position might also contribute to this shunt. Reports indicate that obese patients may be more likely to develop dorsal atelectasis than non-obese patients. The investigators hypothesized that opening the body position angle at the waist from a typical head of bed at 30 degrees to one similar to a more upright reverse trendelenburg position, would alter the position of the diaphragm downward, allowing for improved aeration of lung bases. Thus, the investigators examined the upright body positioning in mechanically ventilated patients with ARDS primarily by evaluating for effects on oxyhemoglobin saturation (O2sat), Tidal Volume (TV) and Respiratory Rate (RR).

Outcome Measures

Primary Outcomes (1)

  • Number of participants with change in hemodynamic stability from baseline when placed in upright position

    Hemodynamic stability will be determined by changes from baseline in blood pressure or heart rate when participants are placed in an upright position.

    Three hours

Secondary Outcomes (3)

  • Number of participants with change in Oxyhemoglobin Saturation from baseline when placed in upright position

    Three hours

  • Number of participants with Change in Tidal Volume from baseline when placed in upright position

    Three hours

  • Number of participants with change from baseline in Respiratory Rate when placed in upright position

    Three hours

Other Outcomes (1)

  • Number of participants with change from baseline in respiratory system compliance when placed in upright position

    Three hours

Study Arms (1)
