When your SpO₂ levels reach 85% or lower on your pulse oximeter, it means you are in hypoxia. Simply reaching this number is enough to trigger the benefits! We advise holding your breath for around 2 minutes after your SpO₂ levels drop to this percentage. If you can not hold your breath for 2 minutes then take in a sip of air and exhale again to hold your breath a bit longer.
