Nutrition and the use of metabolic assessment in the ventilator-dependent patient
Abstract:
Nutritional support is an important aspect of care in hospitalized patients, especially those receiving mechanical ventilation. While nutritional assessments can help guide the clinician in determining appropriate caloric intake requirements and refeeding schedules, few tools exist to evaluate the consequences of over- or underfeeding. Metabolic assessment using indirect calorimetry is a new method of nutritional assessment for use at the bedside of the weaning patient. The data obtained from a metabolic assessment can be used to adjust formulas and total caloric intake as well as differentiate between dead space and elevated carbon dioxide production as reasons for persistent hypercarbia.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
