Questions and Answers
What role does oxygen play in wound healing?
What role does oxygen play in wound healing?
- It only promotes platelet aggregation.
- It reduces inflammation in the wound.
- It has no significant impact on wound healing.
- It aids in preventing infection and stimulates tissue repair. (correct)
What occurs in the microenvironment of an early wound due to high oxygen consumption?
What occurs in the microenvironment of an early wound due to high oxygen consumption?
- It becomes depleted of oxygen and is often hypoxic. (correct)
- The risk of infection significantly decreases.
- It becomes more oxygen-rich than normal.
- All healing processes are accelerated.
What is one of the potential benefits of hyperbaric oxygen therapy?
What is one of the potential benefits of hyperbaric oxygen therapy?
- It may improve the healing process in hypoxic conditions. (correct)
- It promotes only surface healing, not deeper tissue repair.
- It increases the risk of infection in wounds.
- It eliminates the need for wound cleanliness.

Wound Hypoxia
Low oxygen levels in a wound, hindering healing.

Study Notes
Oxygenation
- Oxygen is crucial for wound healing
- Prevents infection, promotes angiogenesis (formation of new blood vessels), and collagen synthesis and re-epithelialization
- High oxygen consumption by active cells in the wound creates a hypoxic microenvironment
- Impaired oxygenation hinders wound healing
- Hyperbaric oxygen therapy can improve healing in a hyperbaric oxygen chamber
- 100% oxygen exposure can accelerate healing
Infection
- Contamination: Presence of non-replicating microorganisms without causing any infection
- Colonization: Presence of replicating microorganisms in the wound without causing damage
- Infection: Presence of replicating microorganisms in the wound causing tissue injury (needs antibiotics)
