Estimating Nutrition Needs Flashcards
a person is catabolic under these 3 conditions
malnutrition, hypermetabolism, inflammation
Why is protein catabolized rapidly during stress?
for utilization of amino acids for gluconeogenesis
during the metabolic stress response, energy expenditure is ______
increased
during the metabolic stress response, nitrogen losses are
increased
during the metabolic stress response protein synthesis is
increased
during the metabolic stress response blood sugar
increases (hyperglycemia)
during the metabolic stress response, clearance of fatty acids _____ leading to hypertriglyceridemia
decreased
RDA of protein for healthy adults
0.8- 1
If a patient’s BMI is <30 in the ICU protein needs can be estimated at
1.2-1.5 g/kg actual body weight
Indications to use indirect calorimetry
BMI <20.5, BMI >80, concern for overfeeding, unexplained high vent needs
contraindications of indirect calorimetry
chest tube leak, ET cuff leak, ECMO, FIo2 >60%, claustrophobia, high volume overload, recent HD
If performing IC on a continuously fed patient, how long should the TF be held?
7 hours
If performing IC on a bolus fed patient, how long should the TF be held?
4 hours
How often should IC be performed in the critically ill?
every 3-4 days
Name the essential amino acids
