Rationale

The section was updated to include more recent evidence regarding the diagnostic and prognostic utility of TcPO₂. Chuter (2023) provides a high-level systematic review confirming its role in the diabetic population, which is a primary use case for this test. Zhang (2026) was integrated to show the utility of TcPO₂ in monitoring response to advanced therapies, broadening the clinical application described in the text. Abbreviations were expanded per instructions.

* AssessesTranscutaneous oxygen pressure (TcPO₂) assesses skin oxygenation,oxygenation and predicts wound healing.healing potential.
* In patients with chronic limb-threatening ischemia (CLTI) or diabetic foot ulcers (DFU), values >50 mmHg =suggest good healing potential.
*potential, whereas <20 mmHg =indicate poor healing potential.potential [@schepers2010] [@conte2019-gvg][@conte2019-gvg].
* Systematic reviews confirm that TcPO₂ is a reliable non-invasive bedside test for predicting wound healing and amputation risk in the diabetic population [@chuter2023-b].
* TcPO₂ also serves as an objective measure of microcirculatory improvement following regenerative interventions, such as mesenchymal stem cell therapy [@zhang2026-b].
