Summary
This completed study with 15 healthy volunteers tested how breathing low-oxygen and high-carbon-dioxide gas mixtures for six minutes changes heart function and blood flow. Researchers measured cardiac output and perfusion index under three conditions: low oxygen alone, high carbon dioxide alone, and both together. The goal was to understand the body's immediate response to these gas changes.
