One-step N2-dilution technique for calibrating open-circuit VO2 measuring systems

摘要: A simple one-step procedure that eliminates the need to calibrate O2 analyzer or measure flow past animal is described for calibrating an open-flow respirometry system. The technique particularly useful situations of high ambient humidity and large active animals where a mask employed capture expired gases. measured N2 used equations describing are given, accuracy method discussed in detail. errors associated with compared those more conventional procedures usually smaller.
