Question

Quizplus · Accepted Answer

Excessive calorie intake can raise PaCO₂ sufficiently to make it difficult to wean a patient from the ventilator.A balanced regimen with both lipids and carbohydrates providing the nonprotein calories is optimal for patients with respiratory compromise,and these patients need to be reassessed continually to ensure that caloric intake is not excessive.
