EE: Gas Collection Devices (2013)

Assessment
Is there a difference in accuracy of RMR measurements related to different types of gas collection devices (such as facemask, mouthpieces with noseclips or ventilated hood/canopy) in the critically ill population?
- Conclusion
  There were no original research studies identified regarding the differences in RMR measurement accuracy between different types of gas collection devices in critically ill adults.
- Grade: V
  - 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.
