Carbon Dioxide
What It Means
Reflects the body’s acid–base balance and how effectively it regulates pH through respiration and kidney function.
Why It Matters
CO₂ helps show how well the body is managing metabolic load, stress, and recovery through buffering systems.
Why It Matters
Viewed with electrolytes (sodium, chloride, potassium), CO₂ trends can highlight shifts in hydration, breathing patterns, and recovery needs.
