Answer to Question 1
Because nutrient metabolism involves both inspiration of oxygen and expiration of carbon dioxide, and mechanical ventilation is affected by each of these, certainly nutrition support plays a role.
Most importantly, overfeeding, and thus an increase of carbon dioxide production, may increase dependency on mechanical ventilation if underlying respiratory status is impaired.
Additionally, malnutrition affects all muscles and ability to perform work.
This weakens respiratory muscles, which further alters ability to ventilate normally.
Malnutrition may also impair immune function, which increases risk of infection and other complications.
Since mechanical ventilation impairs one's ability to engage in oral food intake, nutrition support is required to prevent malnutrition/further clinical complications.
