Drowsiness leading to confusion and labored breathing occurs with increasing CO2 exposure above 2,000 PPM. Ambient air is about 350 PPM CO2. Zeroing a sensor on ambient air means your reading is 350 PPM. Low Oxygen Alarm values are 19.5% (warn) and 18% (evacuate). When the CO2 IDLH of 3% is reached, the Oxygen level is not near alarm but the effects of 3% CO2 are severe headaches and confusion!
