(1)It is the elimination of carbon dioxide
(2)Maybe it’s a problem that can affect you before you run out of oxygen
(3)Human respiration is primarily determined by carbon dioxide concentration
(4)When the concentration of carbon dioxide in the blood increases >> Breathing becomes short >> promotes oxygen supply and lowers carbon dioxide concentration >> Breathing becomes normal
(5)Works in this order
(6)Of course, even if the oxygen level in the blood decreases, it’s stimulated by breathing. Secondary
(7)What would happen if the concentration of carbon dioxide in the air exceeded the normal level of 004? The Industrial Revolution is 0028
(8)- Ventilated room 0025~007 clear
(9)- a poorly ventilated room
(10)007~01 Something’s not good
(11)01-02 Headache and stiff shoulders Your dryness may be due to lack of ventilation!
(12)03~05 Dizziness, nausea, sleepiness, decreased attention
(13)I’m sure I’m in the wrong place
(14)More than 3 respiratory problems appear
(15)4 or more headaches, tinnitus, increased blood pressure, decreased heart rate, fainting vomiting
(16)6+ respiratory rate increased dramatically
(17)I’m pretty sure it’s my grave
(18)8 to 10 unconscious cyanosis
(19)More than 20 central nervous system disorders are beyond the point of normal recovery
(20)30+ deaths
(21)So even if there’s enough oxygen in an enclosed area, if you don’t get rid of carbon dioxide well, you can’t guarantee the safety of the people there
(22)A famous case is Apollo 13
(23)It’s quite a famous anecdote that astronauts didn’t run out of oxygen to breathe after the accident, but if they couldn’t get rid of the CO2 accumulated inside Apollo 13, they would die from the above symptoms, and they would suffer from a single-standard integration after an incompatible mistake
(24)How did you install a carbon dioxide removal device by applying duct tape
(25)What about a submarine
(26)Carbon dioxide removal from submarine CO2 scrubbing is one of the important equipment in submarines because the crew suffers from low-level symptoms and cannot come back to life, let alone operate
(27)In the past, we used a lot of carbon dioxide absorbent called soda lime calcium hydroxide sodium hydroxide, and now we use lithium hydroxide, and we need to make sure that these air purifiers with carbon dioxide removal function work well in submarine test navigation
(28)If you look on the Internet, there is an anecdote that the Navy inspected hard when it was acquired from a former 209 or German shipyard to confirm that the air purifier had a low carbon dioxide removal performance and demanded action. Source
(29)Despite these equipment, the carbon dioxide concentration in the submarine is about 04 to 1, which is about 10 times higher than the normal atmosphere, so I think I know how poor the submarine working environment is and why the crew is deteriorating their health
(30)Was there a CO2 removal system in the submersible that crashed this time? Five people in that narrow ship, pretty quickly
(31)CO2 levels will go up
(32)In conclusion, there’s no fine dust these days. Let’s ventilate at night
