Learn how to calculate EE from VCO2 measurement as a surrogate to IC.

Hear results from a preliminary study demonstrating how:

  • The estimation of the EE:VCO2 may be sufficiently accurate to be considered as an alternative to IC:EE
  • EE:VC02 is more precise than frequently used predictive equations
  • To consider what RQ should be used when applying the VC02 alternative to REE
  • The study is being expanded to automate the EE:VCO2 calculation with the goal of informing patient-centric nutrition plans to avoid under or overfeeding, help reduce length of stay, and improve outcomes with complex ICU, intubated and ECMO patients
