Note: GASYSS3 Gas Analysis System requires SS11LB Airflow Transducer.

Lesson Version Log

• December 2019: new version for GASSYS3 Gas Analysis System and SS11B Airflow Transducer
• May 2015: updated for BSL 4.0.1
• Jan 2012: optional 2-point calibration added

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)

Lesson Hardware

GASSYS3 is the currently shipping Gas Analysis Module and it requires the SS11LB Airflow Transducer.
The lesson can also be recorded using an older GASSYS2 with SS11LA and module-specific template and instructions.
