Oxygenation and perfusion to the wound site play a pivotal role in the wound healing process. Adequate blood flow is essential because it delivers not only the necessary oxygen but also nutrients and immune cells that are critical for tissue repair and regeneration. Oxygen is vital for cellular metabolism and energy production, both of which are key in the healing phases, including hemostasis, inflammation, proliferation, and maturation. When oxygen levels are compromised, healing can be delayed, and the risk of infection increases.

Perfusion ensures the transportation of these vital components to the wound site. Poor circulation can lead to ischemia, thereby prolonging inflammation and creating an unfavorable environment for healing. Optimal oxygenation and perfusion are necessary for effective collagen synthesis, angiogenesis (formation of new blood vessels), and the overall restoration of skin integrity.

While factors such as the age of the patient, choice of wound care product, and timing of dressing changes also play a role in the healing process, they do not match the critical importance of oxygen and blood flow in terms of cellular and physiological support needed for effective wound healing.
