OSHA's maximum safe level is 3% (30,000 ppm); lethal concentration (death in 30 minutes) is 10% (100,000 ppm)

Higher than 50
0.4% w/v in your blood is the lethal does of alcohol.A liter of hard liquor, such as spirits or vodka.
2.8 blood alcohol level in a female
yes
CO2 in the blood stream can be measured from bicarbonate in the blood or pCO2 (partial pressure). Normal CO2 measured from bicarbonate is 22-28 mEq/L Normal pCO2 is 35-45 mmHg
That is a potentially lethal BAC.
An increase in blood CO2 levels will result in an increase in carbonic acid formation, and therefore lower the pH.
The questions leads towards which physiological important gases the blood contains.When the blood moves TO the lungs it has both CO2 (carbondioxide) and O2 (oxygen). However the level of oxygen is lower, and the level of CO2 is higher than with blood coming from the lungs.
If the concentration of CO2 in the lungs was higher or equal the concentration in the blood, there will be no diffusion of CO2 in the air of the lungs. The person will suffocate in this situation.
Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.
CO2 regulates the body breathing functions. The normal range is 23 to 32. A level of 31 is within the normal range. High levels of CO2 could indicate a breathing problem.
Basically, because you do not exhale, metabolic waste products (such as CO2) remain in the blood.
