  • Assessment
    What is the energy measurement difference when using different types of gas collection devices, such as facemask, mouthpieces with nose clips, or canopy (e.g., ventilated hood)?
    • Conclusion

      Under rigorous control with no air leaks occurring, four studies of neutral design suggest comparable RMR measures in free-living adults can be achieved using either canopy, mouthpiece and nose clip, or facemask gas collection devices.  However, in one neutral quality study, mean RMR was 7% higher for facemask and 9% higher for mouthpiece compared to canopy.  Because of conflicting data and recent advances in technology, further studies comparing gas collection devices are needed, including in clinical populations.

      The first 5 minutes of data should be discarded no matter which of the three collection devices are used.

    • 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.
