Measurement of VO2, VCO2, and evaporative water loss with a flow-through mask
Abstract
Equations for the calculation of VO2, VCO2, and evaporative water loss were derived for use of a paramagnetic gas analyzer with a flow-through respirometry system and an open or closed mask. The magnitude of errors involved in the determination of VO2 with no CO2 absorbent are small (+/-3%) but may be greater if no H2O absorbent is used, unless an appropriate correctionis made for evaporative water loss. Data collected for hummingbirds (Selasphorus sasin) and monitor lizards (Varanus gouldii) indicate the validity ofthe technics described for the measurement of RQ and evaporative water lossand demonstrate the use of paramagnetic gas analyzers in monitoring respiratory patterns.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
