Abstract

Resting metabolic rate (RMR) measurement by indirect calorimetry is often used in acute care; however, indirect calorimetry is rarely performed on patients treated at home with complex therapies such as home parenteral nutrition (HPN). A new handheld indirect calorimeter is now available to measure RMR and oxygen consumption (VO₂). This is a case study of a 35-year-old female who had her RMR and VO₂ measured at rest while receiving cyclic HPN and while off of HPN over a period of 8 days. Results indicate that her RMR was higher while receiving HPN. Measuring RMR in patients receiving HPN may be very beneficial to avoid underfeeding and overfeeding. It will be important for the clinician to note if the patient is receiving HPN at the time of the measurement because RMR may be affected by HPN infusion.
