This evaluation measures end-tidal carbon dioxide (CO2) in order to identify and retrain breathing habits that compromise respiration and decrease cognitive and physiologic performance. When breathing habits have compromised reflex-generated CO2 they can cause, trigger, exacerbate, and perpetuate a wide range of effects (i.e., symptoms and deficits) that often are attributed mistakenly to other unrelated causes. The use of this precise CO2 analyzing instrumentation is the only effective means to determine if a learned breathing habit compromises respiration and performance
