Energy Expenditure

EE: Rest Period Duration (2013)

• Assessment
  How long of a rest period is needed prior to the measurement of resting metabolic rate (RMR) to ensure accuracy in the critically ill population?

  • Conclusion

    One study reports that rest periods greater than 30 minutes are not necessary in critically ill adults. Additional research is needed to confirm this and to determine the minimum time to recover after routine ICU care, taking sedation level into account.  

     

  • 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.
