CO₂ foot bathing salvaged 83% of limbs at risk of amputation in circulation studies
CO2 foot bathing (1,000 ppm, 37°C, 10 min twice daily for >2 months) salvaged 83.1% of critical limb ischemia (Fontaine IV) limbs with ulceration or gangrene from amputation in peripheral arterial disease patients.
What this means for you
When circulation to the feet and legs is severely compromised, tissue can break down rapidly. This finding suggests that dissolved CO₂ absorbed through the skin may help restore enough blood flow to support tissue recovery — a response that matters for anyone managing poor peripheral circulation, cold extremities, or slow-healing wounds in the lower limbs.
