Date: February 22, 2023
Time: 3:00 – 4:30 PM ET

Estimating calorie needs during hospitalization can be a complex assignment given the dynamic nature of energy requirements that vary based on body composition, disease state, and surgical interventions. Indirect Calorimetry (IC) is the gold standard of energy measurement in the hospital setting and is a great tool to help understand resting energy requirements. IC can be utilized in many patient populations, including those spontaneously breathing and on a ventilator. Although every assessment will routinely provide resting energy expenditure (REE) and respiratory quotient (RQ), it is essential for users to understand all test results and be able to overcome technical challenges according to specific clinical circumstances. This webinar will take a bedside approach to highlight common and unique scenarios while utilizing indirect calorimetry and provide user tips for IC assessment during mechanical ventilation, mask, and canopy tests.

    Learning Objectives

    1. Describe the role of indirect calorimetry in determining the caloric needs of hospitalized patients.
    2. Determine patient populations who would benefit from indirect calorimetry as part of the patient assessment.
    3. Identify which values are necessary to interpret results provided by indirect calorimetry.
