1:53 Exhaled Breathhold with SpO2 and heart monitor (audio!)
I really pushed myself here, trying to get to 2 minutes, but fell a few seconds short. The oxygen saturation dropped from 99% to 64% after the end of breathhold. It was tough! Strong contractions near the end. Heartbeat visible in abs and neck. Watch in HD quality to clearly see the monitor.
