  • Assessment
    For healthy adults, how many times within a 24-hour period should indirect calorimetry measurements be taken to ensure accuracy?
    • Conclusion

      Two high quality studies (one in healthy females and one in males and females) recommend a single measurement is sufficient to represent resting metabolic rate (RMR) in a 24-hour period; though the first 5 minutes should be discarded.

    • Grade: II
      • 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.

    How many times within a 24-hour period should indirect calorimetry measurements be taken to ensure accuracy acccording to a study in a Veterans Health Administration transitional skilled care unit ?
    • Conclusion

      Setting: Veterans Health Administration transitional skilled care unit

      One study of moderate research quality in males residing in a Veterans Health Administration transitional skilled care unit recommends a single measurement is sufficient to represent resting metabolic rate (RMR) in a 24-hour period; though the first 5 minutes should be discarded.

    For critically ill, ventilated patients, how many times within a 24-hour period should indirect calorimetry measurements be taken to ensure accuracy?
    • Conclusion

      One measurement is sufficient for hospitalized, ventilated patients in a 24-hour period if steady state is achieved. In individuals unable to achieve steady state or tolerate measurement conditions,* two or more nonconsecutive single measurements may improve measurement value.
