What is a primary treatment to support lung function in patients with respiratory issues?

Oxygen supplementation is a primary treatment to support lung function in patients with respiratory issues because it directly addresses the deficiency of oxygen that may occur in conditions such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, and other respiratory disorders. Many patients with compromised lung function experience hypoxemia, which is low oxygen saturation in the blood. Administering supplemental oxygen increases the amount of oxygen available to the body, helping to improve oxygenation of tissues and alleviate symptoms like shortness of breath, fatigue, and confusion that can arise due to inadequate oxygen supply.

Other treatment options may play important roles in managing specific conditions but do not primarily target the immediate need for adequate oxygenation in respiratory patients. For instance, increased carbohydrate intake isn't specifically beneficial for lung function and could even lead to increased production of carbon dioxide during metabolism, which may exacerbate respiratory issues. Fluid restriction is typically not associated with improving lung function; instead, it may be indicated in situations where fluid overload is a concern. Antibiotic therapy is crucial for managing infections but primarily addresses underlying causes rather than directly improving lung function.
