Research with Lumen

Get In Touch

Unlike metabolic carts, Lumen focuses exclusively on CO2 and does not measure oxygen levels or consumption.

Results are delivered in real time through a simplified research-friendly version of the Lumen app and stored for later reference.

How Lumen works

  • Participant breathes in through Lumen
  • Holds breath for 10 seconds
  • Breathes out through Lumen

The Lumen device measures CO2 and flow rate during the exhale to identify the peak CO2 level equivalent to alveolar gaseous concentration.
