What Researchers Did
Researchers retrospectively and prospectively analyzed transcutaneous oxygen measurements in room air and under hyperbaric oxygen conditions in 190 patients with foot wounds to determine their effect on healing.
What They Found
A responder group, defined by transcutaneous oxygen measurements greater than 200 mmHg under hyperbaric oxygen, showed a sensitivity of 0.80 and a positive predictive value of 0.88 for wound healing. This predictive ability was observed in 190 patients with foot wounds, regardless of room air measurements, when hyperbaric oxygen was used as an adjunct.
What This Means for Canadian Patients
This research suggests that measuring transcutaneous oxygen levels during hyperbaric oxygen therapy could help predict wound healing for Canadian patients with challenging foot and ankle wounds. Such objective measurements could guide treatment decisions, potentially improving outcomes by identifying those most likely to benefit from hyperbaric oxygen as an adjunctive therapy.

Study Limitations
As a retrospective study, it may be subject to inherent biases and limitations in controlling all variables.
