The tests that measure your breath. CO₂ tolerance, BOLT, resting rate, exhale control, power capacity.
Auralize measures one slow, controlled exhale after a guided warm-up. It is a proprietary respiratory-control baseline—not a blood-gas test or a BOLT breath hold.
BOLT times a comfortable post-exhale pause to the first clear urge to breathe. It is a subjective training baseline—not a direct oxygen, CO₂, or lung-function measurement.
A quiet breathing-frequency count that provides one useful respiratory vital sign. It must be interpreted with age, health, symptoms, medication, and measurement conditions.
A short Auralize task that records how long you can sustain a controlled, quiet exhale under a repeatable protocol.
A short assessment that estimates your readiness for power-breathing rounds and sets the pacing for future practice.
