What happens if you only breathe your own exhaled air. Do not do this unsupervised. The subject in the video is under medical supervision.

  • I'm quite surprised that your heart rate remained at 80bpm, even as the amount of breathable oxygen got seriously low.

  • @Robh1966

    This happens with freedivers. the heartrate either stays normal or goes lower when breath holding until O2 levels are restored at the surface.
