COSMED's Fitmate has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup. “First principles” systems are advantageous in validation testing because their calibration is based solely on easily measured and verified quantities such as length and time (See: Gore CJ, Catcheside PG, French SN, Bennett...

COSMED's Quark CPET has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup. “First principles” systems are advantageous in validation testing because their calibration is based solely on easily measured and verified quantities such as length and time (See: Gore CJ, Catcheside PG, French SN, Bennett...

Adequate nutrition is of paramount importance in critically ill patients, as it can result in less muscle wasting, decreased length of hospital stay and decreased mortality.  Since metabolism, resting energy expenditure (REE) and nutritional status are changing during the different phases of critical illness, it is difficult to ensure adequate nutritional intake. Indirect calorimetry is considered...

Evidence is growing that the individual adjustment of energy targets guided by indirect calorimetry (IC) can improve outcome. With the development of a new generation of devices that are easier to use and rapid, it appears important to share knowledge and expertise that may be used to individualize nutrition care. Despite the focus of this tutorial being on one contemporary device, the principles...
