What Researchers Did
Researchers conducted a retrospective review of 142 patients undergoing hyperbaric oxygen therapy for lower-extremity wounds to evaluate if in-chamber transcutaneous oxygen measurement could determine optimal treatment pressure.
What They Found
Overall, 59% of patients achieved healing. Among those treated at 2 atmospheres absolute (ATA), the healing rate was 70.6% if transcutaneous oxygen pressure (TcPO2) was greater than 250 mmHg, compared to 11.8% if TcPO2 was less than 250 mmHg (P<0.001). Additionally, 41% of patients with TcPO2 less than 250 mmHg at 2 ATA attained TcPO2 greater than 250 mmHg at 2.4 ATA.
What This Means for Canadian Patients
This suggests that in-chamber transcutaneous oxygen measurement can help personalize hyperbaric oxygen therapy by identifying the most effective pressure for wound healing. Patients may benefit from adjusted treatment pressures to maximize therapeutic outcomes and minimize risks.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The retrospective design and focus on lower-extremity wounds are key limitations of this study.
