EE: Body Positions (2013)

  • Assessment
    Is there a difference in accuracy of RMR measurements related to the effects of different body positions in the critically ill population?
    • Conclusion

      Limited research reports that posture can affect measurement of resting metabolic rate (RMR) in some critically ill patients. One study reported that energy expenditure was significantly greater in the supine position than in the 30-degree head of bed elevation post-operatively, possibly attributed to increased work of breathing because these patients were not mechanically ventilated. Further research is necessary to determine if there are differences between sitting upright and lying semi-recumbent at 30 degrees in intubated vs. non-intubated patients.

       

       

    • Grade: III
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    • Evidence Summary: Is there a difference in accuracy of RMR measurements related to the effects of different body positions in the critically ill population?
