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
