What this trial studies

This observational study aims to evaluate the use of normobaric oxygen therapy in patients with chronic permanent ischemia of the lower limbs, a severe condition characterized by insufficient blood flow. The study will assess the proportion of patients receiving this therapy in routine clinical practice and its potential benefits in improving patient outcomes. By analyzing the Wound, Ischemia, Foot Infection Score (WIfI score), the research will explore improvements in various aspects of the condition, providing insights into the therapy's effectiveness. The hypothesis is that normobaric oxygen therapy may offer medical benefits compared to standard care without oxygen therapy.

Who should consider this trial

Good fit: Ideal candidates for this study are hospitalized patients diagnosed with chronic permanent ischemia, indicated by resting TcpO2 values below 30mmHg.

Not a fit: Patients with acute or decompensated heart or respiratory failure, or those with severe chronic obstructive pulmonary disease (COPD), are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence supporting the use of normobaric oxygen therapy as a beneficial treatment for patients with critical limb ischemia.

How similar studies have performed: While there have been studies on hyperbaric oxygen therapy, the specific application of normobaric oxygen therapy in this context is less explored, making this approach relatively novel.
