World Record Shattered: Diver Achieves Unprecedented Breath-Holding Dive of 29 Minutes and Beyond Underwater
In a breathtaking feat of endurance and determination, Vitomir Maričić, a Croatian diver, has set a new world record for the longest time spent underwater without breathing. On June 14, 2023, Maričić held his breath for an astonishing 29 minutes and three seconds, shattering the previous record by almost five minutes.
Before attempting this remarkable feat, Maričić underwent a denitrogenation process using a tank of pure oxygen. This process fills red blood cells with as much oxygen as possible and dissolves oxygen into the blood plasma, allowing his lungs to take in around three liters of oxygen per breath. Pure oxygen also helps wash nitrogen out of the blood, supercharging it with oxygen.
The performance took place in a three-metre pool inside the Bristol Hotel in Opatija, Croatia. The event was witnessed by five official judges and around 100 spectators, with the record being officially recognized by Guinness World Records.
In a medical setting, doctors might use this technique to expand an unconscious patient's 'safe apnea time'. However, it's important to note that under normal circumstances, this is something that cannot happen. Even with the assistance of pure oxygen, holding your breath for half an hour is still a major achievement.
Maričić's blood oxygen levels were five times the normal limit before he held his breath. Typically, the lungs of a healthy adult hold about 450ml of usable oxygen. The use of pure oxygen significantly increased Maričić's breath-holding capacity.
Before purging his blood of excess nitrogen, Maričić breathed pure oxygen for 10 minutes. This is a crucial step in the denitrogenation process, as it ensures that his body is as oxygen-rich as possible before holding his breath.
Maričić's feat has earned him the Guinness World Record for the "longest time breath held voluntarily underwater". This technique, while not commonly used for breath-holding records, is employed in medical situations.
The Daily Mail reported on this incredible achievement, highlighting the extraordinary determination and physical prowess required to achieve such a feat. Maričić's record-breaking performance is a testament to human resilience and the lengths people will go to push the boundaries of what is possible.
