Marichich set a new breath-holding record. This was reported by Zamin.uz.
This result places him among ordinary seals, as seals can fill their lungs with 90 percent air in one breath. In humans, this figure is only 20 percent.
The freediver used pure oxygen to remove excess nitrogen from his blood. He breathed pure oxygen for ten minutes and then held his breath.
As a result, the oxygen level in his blood increased fivefold compared to usual. A healthy adult lung typically can absorb 450 milliliters of oxygen because only 21 percent of air consists of oxygen.
When breathing pure oxygen, the lungs absorb three liters of oxygen with each breath, expelling nitrogen from the blood. For most people, the safe breath-holding time after breathing pure oxygen is eight minutes.
This is significantly less than Marichich's time without air. This achievement is important for expanding the respiratory capabilities of the human body.
