How does hyperbaric oxygen therapy primarily affect leukocytes?

1. Decreases function and efficiency

2. Increases their function and efficiency

3. Has no effect on leukocytes

4. Causes them to rupture

The correct answer is: Increases their function and efficiency

Hyperbaric oxygen therapy primarily increases the function and efficiency of leukocytes, which are the white blood cells crucial for the immune response. When subjected to hyperbaric conditions, oxygen levels in the blood significantly increase, facilitating a hyperoxic environment. This heightened oxygenation enhances the leukocytes' ability to locate and eliminate pathogens, improving their bactericidal activity. The therapy also stimulates the production of reactive oxygen species (ROS) and promotes important processes such as chemotaxis, phagocytosis, and the overall immune response. By improving the metabolic functions of leukocytes, hyperbaric oxygen therapy plays a vital role in promoting healing, particularly in chronic wounds and infections, where compromised blood flow and oxygenation are prevalent. In summary, the correct choice reflects the positive impact of hyperbaric oxygen therapy on leukocyte functionality, aligning with the therapeutic goals of enhancing the body's capacity to combat infections and heal wounds.
