Oxygen therapy to heal diabetic foot wounds

This is a registry study that will look back at 10 years of patient records to compare two groups: people who received hyperbaric oxygen therapy (HBOT) — a treatment where you breathe pure oxygen in a pressurized chamber — along with standard wound care, versus people who received standard care alone. The study will measure whether adding this oxygen therapy helps prevent amputations, reduces hospital stays, and improves survival in people with diabetic foot ulcers.

Diabetic foot ulcers can be serious and sometimes lead to amputation. Researchers want to understand whether adding hyperbaric oxygen therapy to standard treatment can help heal these wounds better and prevent complications like amputation.
