5 minute breath-up, 20 breaths, empty stomach, one warm-up with a few contractions. Generally contractions at 3.15-3.45. All SpO2 measurements from MEDAIR IPX2 OXY finger - value taken at its lowest point usually 25 seconds after breath hold.

How long does the effect of (hyper)ventilation stay in the body:
Hyperventilation (or heavy ventilation) reduces the levels of CO2 and postpones the urge to breath. Lovely. On the other hand it agitates your system, mainly your heartrate - not so good. So is there a way of getting rid of the some of the CO2 without getting a higher heart rate? How long will the effects of hyperventilation remain in the body. If you hyperventilate for 30 secs (20 quick breaths) and then delay the start of the breathhold.

What are the conclusions? Well, it is not so important to breath deep or heavy during the last 30 seconds before a breath hold. Better is to use those 30 seconds to calm down. There is actually better values if waiting 30 sec, but that could be explained by the effects of a spleen release of the first breath hold (5 minutes rests where used inbetween the breath holds).
