Six minutes is Ye Jian's limit, but for many people, six minutes of underwater hypoxia has already lost their lives.
Da Yu sighed again in her heart, and then converged her mind for the second test. No matter how powerful she was, she would not belong to the navy, nor would she belong to the storm commando.
But the female soldier can surpass the male soldier, whether she belongs to her own unit or not is an exciting thing.
Ye Jian didn't know the churn in Dayu's heart, walking out of the testing room, she quickly adjusted her body's various states to enter the high C02 tolerance and adaptation test.
This is the training that the frogman must learn, and it is also a must-test for the selection of members of the Storm Commando.
"This is the form of our C02 tolerance training. You can take a look at it." The giant shark who accompanied and recorded the whole process became quiet, standing in the clear water and said to Ye Jian, who was ready for work: "The body rest time is 15%. The second is decreasing, while the apnea time remains the same. We have a 30-minute test. You may feel a little uncomfortable, and you may even experience nausea and vomiting."
"There is a coral island below. You need to dive into the bottom of it. The bottom is about 15 meters from the sea. Remember Ye Jian, we need to record your best personal scores and your worst scores. Within thirty minutes, I To find out whether your grade average is passing."
Gao co2 is a dangerous test that does not carry any air source and only dives into the water with one breath. When Ye Jian closed her breath and dived to the bottom of the sea, she closed her eyes and kept her swimming like a fish while she closed her breath. Swim into the bottom of the coral.
The oxygen content in the blood began to drop, and the high concentration of carbon dioxide gradually made the body feel uncomfortable. The diaphragm muscles that began to twitch told Ye Jian that she needed to breathe and needed to rise out of the water to get oxygen.
Relax, relax, the body must relax, let your body and spirit not become afraid of the increasing CO2 content in the body, listen to the sound of water, feel the joy of fish swimming by, avoid being disturbed by factors such as fear , Ye Jian didn't ascend water quickly until the blood oxygen level was low to the limit.
"The rest time should not be too long, otherwise the accumulated C02 will be excreted because the rest time is long enough, and it will not achieve the purpose of accumulating high C02. Once it surfaced for more than 30 seconds, the cumulative effect of C02 would be very bad. Ye Jian, you have to control the ventilation within 20 seconds to dive into the sea again."
Da Yu's very strict voice kept reminding Ye Jian, and when he waited for Ye Jian with a chronograph in one hand to dive into the sea again, the expression on his face would become solemn.
The 20-second breath exchange is actually harsh for a recruit, but he really wants to know whether Ye Jian can surpass the recruit again, and the risk factor is a bit big for the recruit within 20 seconds to breathe.
For recruits, the risk factor for air exchange within 20 seconds is a bit high, but for the Storm Commando, it takes a long time to exchange air after 20 seconds.
Each breath in the process of full breathing will exchange the gas in the lung capacity. The frogman rests for 15 seconds and immediately enters the next round of high c02. Give Ye Jian an extra 5 seconds. After several rounds of testing, it is finally considered feasible and conservative. .
He dived into the bottom of the sea 15 meters under one breath, and Ye Jian, who held his breath for 2 minutes, rushed up again and rested for 15 seconds. This cycle continued for 30 minutes. After the whole test, Ye Jian, who was hardworking and hardworking, felt that all his strength seemed to be exhausted. Was evacuated.
The big shark looked at the female soldier who was wet all over and kept the arrogant soldier even when she was tired, and then looked at the record on the table, the apple jelly knot was very light and lightly sliding up and down a few times... This record is enough for the comrades in their team. I was so shocked that I dropped my chin.
