Question: 1 / 400

How do respiratory infections impact the body's oxygen levels?

They increase oxygen levels

They have no effect on oxygen levels

They can decrease oxygen levels

Respiratory infections can significantly impact the body's oxygen levels by causing a decrease in oxygen saturation. When an individual is infected, the respiratory system can become compromised due to inflammation, mucus production, and the presence of pathogens in the airways and lungs. These changes can obstruct airflow, reduce gas exchange in the alveoli, and lead to impaired oxygen uptake.

During infections such as pneumonia, bronchitis, or viral illnesses like influenza, the efficiency of the lungs in oxygenating blood is reduced. As a result, oxygen levels in the bloodstream may fall, leading to hypoxemia, which can affect overall bodily functions and result in symptoms like shortness of breath and fatigue.

This understanding is critical, as healthcare professionals must monitor and manage oxygen levels in patients with respiratory infections to ensure adequate oxygen delivery to tissues and prevent complications.
