Fyristillið tykkum at taka eina síðstu anding, og so halda ondina í 4 minuttir og 24 sekund, meðan fyrst ein vekt dregur tykkum 214 metrar niður, og ein ballón síðani hálar tykkum upp aftur. Og enntá skula steðga eina løtu á veg upp aftur, 10 metrar undir vatnskorpuni, til at umganga dykkarasjúku. Kava so djúpt, at blóðplasma setur inn í lunguni… sum er gott, tí at tú so umgongur at tey kollapsa. Og við serligum samankroystiligum dykkarabrillum, so at eyguni ikki verða sogin úr høvdinum. Hetta heimsmet eigur eysturríkarin Herbert Nitsch, frá eini kaving í Grikkalandi í 2007.
Herbert Nitsch 214m (702ft) World Record No-limits Dive 2007 in HD from Dan Burton Photography on Vimeo.
Imagine a CLOSED plastic container filled with air is slowly submerged in water. As water pressure increases around it, the container is soon or later forced to crush into itself. Now imagine our lungs as being that plastic container. But what happens when you Freedive? Clearly there is no extra air going into our lungs to equalize the pressures. For years, Doctors used to believe that if Freedivers go deeper than a certain depth, their lungs would “crush” and death would occur. But freedivers s proved them wrong. After further experiments and observations, it was found that a “blood shift” mechanism is present in the human body. As we go deeper in water, blood starts to “shift” from other parts of our bodies and begins to flood our lungs to equalize the outside water pressure. Our heart rate slows down and blood pressure increases.

Handan plastfløskan er vist nokk til at blása út í, og síðani taka luft inn aftur úr, til at tola trýstið í oyrunum
Herbert Nitsch, in his 172m No Limits world record, blew out into a balloon as he descended, sucking the air back in to equalise his ears as he got deeper. Most No Limits divers also use ‘wet equalisation’ when there is no air left for their ears, a practice involving removing their nose clip and flooding their sinuses with water to push any remaining air into their ears.

The eqex, designed by Herbert himself, is the Coca-Cola bottle hanging underneath. Herbert was filling it with air from his lungs at 30meters depth. Afterwards, below 100 meters, he was using this air to equalize!

Puha, tey stríðast eisini við vandanum fyri ‘djúphavs-narkosu’
Narcosis: This, on many occasions, was the initial problem that caused the rest. The free diver made wrong or delayed decisions due to deep waters narcosis.
Og eisini nokk so nice, so bíðaði hann við áðrenn hasar 10 seinastu metrarnar, til andivøddarnir byrjaðu at krampa. Og svam so róliga upp til síðstu metrarnar.
Using his gained time, Herbert would make a decompression stop at about 10meters depth before surfacing, until the diaphragm contractions would start.
Og so bremsaði sletan á botninum frá 4 m/s (14 km/t) til 0 uppá ein hálvan metur (sum følist)
The bottom stop made of water bottles with drilled tennis balls was the best possible stop used. Of course the bottles exploded and can be heard on the bottom camera audio! This crash was hurtful for the diver and also for the sled.
