A practical, evidence-based clinical guide to deciding when hyperbaric oxygen therapy belongs in diabetic foot ulcer care - and when it does not.
Hyperbaric oxygen therapy (HBOT) remains one of the most debated adjuncts in advanced wound care. Positive trials and biological rationale coexist with negative modern studies, low-certainty recommendations, treatment burden, and uncommon but serious risks.
For clinicians facing a nonhealing foot ulcer, the question is not whether HBOT always works or never works. It is whether this patient is likely to benefit after perfusion, infection control, debridement, offloading, metabolic management, and adequate standard care have been addressed.
This clinician-focused guide will help readers:Understand why diabetic foot ulcers fail to heal and where wound hypoxia may contribute.
Evaluate randomized trials, systematic reviews, guidelines, and conflicting clinical evidence.
Distinguish systemic chamber-delivered HBOT from topical and normobaric oxygen therapies.
Identify candidates using Wagner grade, perfusion, treatment response, contraindications, and ability to complete therapy.
Plan treatment, measure response, and decide when HBOT should be continued or stopped.
Recognize adverse effects, serious risks, and essential hyperbaric medicine safety systems.
Practical resources include patient-selection and pretreatment safety criteria, the elements of informed consent, monitoring and adverse-event documentation standards, evidence tables, a patient handout, six teaching cases, and a one-page clinical decision algorithm.
Written for wound-care physicians, podiatrists, hyperbaric clinicians, vascular specialists, nurses, researchers, and healthcare trainees, this evidence-based clinical guide connects diabetic wound healing, chronic wound management, and limb preservation with disciplined decision-making.
HBOT helps some patients, cannot help most, burdens all, and harms a few. This book provides the framework needed to distinguish those groups - and to use HBOT responsibly without overselling its benefits or ignoring its limitations.
