H19 VO2 & RER

This BSL PRO lesson records absolute volume of O₂ and CO₂ in a 60-second interval.

The lesson was updated in May 2015 for BSL 4.0.1 and in Jan 2012 to include an optional 2-point calibration; the graph template gtl and the gtl settings PDF were updated to reflect this change.

Experimental Objectives

1. To obtain absolute VO₂ and RER values for a subject at rest (optional segments include hyperventilation and recovery from exercise).
2. To demonstrate the relationship between VO₂ and RER.

Tasks Performed by the Student

• breath through a mouthpiece
• exercise (optional)
• hyperventilate (optional)
