CO2 levels and guidelines
Below are some CO2 reference levels in general:

400~600ppm

Background (normal) outdoor air level.

600~1,000ppm

Typical level for occupied spaces with good air exchange.

1,000~1,500ppm

Start ventilation of the room.

1,500~2,000ppm

Level associated with complaints of drowsiness and poor air.
Ventilation recommended!

2,000~5,000ppm

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.
Ventilation strongly recommended!

>5,000ppm

Exposure may lead to serious oxygen deprivation resulting in permanent brain damage, coma, and death.
Requires immediate ventilation!
