A shelf-stable oxygen pill could someday replace the need for blood transfusions during emergency surgeries.

Traditional blood transfusions require matching blood types and keeping the supply refrigerated, which is often impossible in emergencies. This conceptual framework proposes an oral supplement based on perfluorocarbons that carries oxygen directly through the digestive system. Once swallowed, the complex creates a systemic reserve of oxygen that the body can draw from if the heart or lungs are struggling. It would be blood-group independent, meaning it could be given to anyone instantly regardless of their type. This liquid breath in pill form would fundamentally change how we handle trauma and massive blood loss on the fly.
