EE: Gas Collection Devices (2013)

• Assessment
  Is there a difference in RMR measurements related to different types of gas collection devices (such as face mask, mouthpieces with noseclips, or ventilated hood/canopy) in healthy and non-critically ill individuals?

  • Conclusion

    Based on the research reviewed, there is conflicting evidence regarding RMR measurements made comparing a ventilated hood with either mouthpiece/noseclip or face mask in healthy adults; this may be due to differences in patient comfort. One study in healthy children reported no significant differences between RMR measurements comparing mouthpiece/noseclip vs. face mask. Additional research comparing gas collection devices is needed.

  • 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 RMR measurements related to different types of gas collection devices (such as facemask, mouthpieces with noseclips, or ventilated hood/canopy) in healthy and non-critically ill individuals?
