Rationale

The section was expanded to include recent systematic review evidence regarding the diagnostic performance of TcPO₂ in diabetic populations and its emerging role as a monitoring tool for regenerative therapies. Abbreviations were expanded on first use as required.

Content Changes

* AssessesTranscutaneous oxygen pressure (TcPO₂) assesses skin oxygenation,oxygenation and predicts wound healing.healing potential.
* >50 mmHg = good healing potential.
* <20 mmHg = poor healing potential. [@schepers2010] [@conte2019-gvg]
* TcPO₂ serves as a bedside predictor for wound healing and amputation risk in patients with diabetes, though its diagnostic performance is variable. [@chuter2023-performance]
* It is also used as a physiological marker to monitor the efficacy of umbilical cord mesenchymal stem cell (UC-MSC) therapy for diabetic foot ulcers (DFU) and peripheral artery disease (PAD). [@zhang2026-safety]
