Why is nutritional support critical in managing ARDS?

Nutritional support is vital in managing Acute Respiratory Distress Syndrome (ARDS) primarily to maintain energy balance and support recovery. Patients with ARDS often experience increased metabolic demands due to the physiological stress of the condition, including inflammation and the increased work of breathing. Providing adequate nutritional support helps to meet these heightened energy needs, ensuring that the body has the necessary resources to heal and recover.

Additionally, proper nutrition contributes to immune system function and helps prevent the catabolism (breakdown) of lean body mass, which is crucial during recovery. Maintaining energy balance also aids in overall rehabilitation, ensuring that patients regain strength and can better tolerate mechanical ventilation and other interventions.

While weight gain may be a secondary consideration, the primary focus is on supporting the patient's metabolic needs and enhancing recovery. Reducing gastrointestinal motility is generally not a goal in ARDS management, as maintaining gut health is important for overall recovery. Although preventing infections is critical in the care of ARDS patients, adequate nutrition plays a more direct role in maintaining energy balance and supporting recovery.
