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.

fNIR Imaging Education System

fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. fNIR optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources […]
