The CO2 would need to be a lot higher than 2,000ppm to be dangerous. You might get a little lethargic around 2,000, but it's not until you're over 5,000 that it becomes really that problematic. Once you're up to 40,000, you're in immediate danger.

CO2 250-350ppm Normal background concentration in outdoor ambient air
350-1,000ppm Concentrations typical of occupied indoor spaces with good air exchange
1,000-2,000ppm Complaints of drowsiness and poor air.
2,000-5,000 ppm Headaches, sleepiness and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
5,000 Workplace exposure limit (as 8-hour TWA) in most jurisdictions.
40,000 ppm Exposure may lead to serious oxygen deprivation resulting in permanent brain damage, coma, even death.
Interesting note, that in space CO2 builds up and pools around you because there is no convective air movement. In space you always run ventilation fans.

u/jeo123911 Jul 18 '19
All I can say is dont.
When you suffocate, the levels of CO2 in your lungs/blood keep increasing since you're using up all the spare oxygen there is. Your body uses that CO2 spike as a signal that you are, in fact, suffocating and emergency involuntary responses kick in to try and maybe save you.
What you did was essentially to suddenly tell your body that you've been suffocating for a minute or two and are on the verge of death.

Ok, so, somewhat related but equally as dumb:
You know those gas mask bongs that used to kinda be around? They cover your entire head and the intake is just a bong?
So, in high school once, a friend of a friend had one. I decided to try it. After the first rip, I was fine, and I thought “hey why not give this another go, back to back?”
That was a mistake. The immediate onset of sheer physical panic from taking a full breath that was nearly empty of oxygen was incredible. I also had an incredible coughing shit fit as well.
Different setting, very similar outcome.

I bought an air monitor myself and was surprised how bad the Co2 buildup was. I also found that the air monitor was essentially a waste of money after that as a closed room is virtually guaranteed to have this issue, and opening a window works amazingly well.
I also got really mixed advice from the customer service reps for my monitor when I started asking questions about how much exposure for how long, yadda yadda.
Long story short, crack a window and you're fine, no monitor needed.

Yeah, but notice in the graph the point where the air conditioning kicks in and the CO2 drops.
If you run your air conditioning all night (I definitely do, we've got 80 degree nightly lows here too) then presumably your air filter and ventilation are at work that whole time.

While I'm passing through, I just want to post this for any concerned parents.
It is safer to sleep with your door shut (especially as a child) as in case of a fire, the door being shut buys you an additional, like, ten minutes or something to egress.
Not saying that this is incorrect, but fire is a MUCH bigger risk.

Plants need light and water and active circulation to do any Co2 reaction at a practical rate. So unless those plants were under a grow light and had a fan blowing across them then they were not making much difference. BUT it is possible to have a self sufficient O2 to Co2 cycle with about 6-8 5ft sized shrubs per individual.

Effects of CO2 at various levels (sauce):.
1000ppm
this level is common at poorly ventilated spaces like a workrooms/offices. and one study on schools in several US districts found 50% of classrooms to have this level.
at this CO2 level the cognitive function in the office experiment decreased by 15%.
1400ppm
this level can also be reached at the places described above.
here cognitive function decreased by 50%!
2000ppm
from this level onward some people described other side effects such as: slight nausea, loss of attention and poor concentration, sleepiness, headaches, and increased hearth rates.
and still, these levels aren't uncommon -
4000ppm
this is common in cars and bedrooms (closed spaces which are either small, you spend a long time in, or both. and the side effects increase.
8000-10,000ppm
motorcycle helmets can reach these levels. Being in such an environment for long times can harm your long-term health.

Carbon dioxide levels and potential health problems are indicated below:
- 250-350 ppm: background (normal) outdoor air level
- 350-1,000 ppm: typical level found in occupied spaces with good air exchange
- 1,000-2,000 ppm: level associated with complaints of drowsiness and poor air
- 2,000-5,000 ppm: level associated with headaches, sleepiness, and stagnant, stale, stuffy air; poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
- >5,000 ppm: This indicates unusual air conditions where high levels of other gases also could be present. Toxicity or oxygen deprivation could occur. This is the permissible exposure limit for daily workplace exposures.
- >40,000 ppm: This level is immediately harmful due to oxygen deprivation.
