What is the difference between inhaled and exhaled air?

Inhalation is the process of intake of air into lungs, whereas exhalation is the process of letting air out from lungs. The composition of air which is inhaled is oxygen and nitrogen mix, while the composition of air which is exhaled is carbon dioxide and nitrogen mix.

Why CO2 is more and o2 is less in exhaled air?

Answer: Exhaled air which contains: more carbon dioxide produced as a waste product of energy production. less oxygen as it has been used in respiration.

How much CO2 do we breathe out?

So breathe easy. The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level—a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)

What does your body do if carbon dioxide levels change?

Hypercapnia is excess carbon dioxide (CO2) build-up in your body. The condition, also described as hypercapnea, hypercarbia, or carbon dioxide retention, can cause effects such as headaches, dizziness, and fatigue, as well as serious complications such as seizures or loss of consciousness.

What are safe levels of CO2 in rooms?

Normal CO2 Levels acceptable levels: < 600 ppm. complaints of stuffiness and odors: 600 – 1000 ppm. ASHRAE and OSHA standards: 1000 ppm. general drowsiness: 1000 – 2500 ppm.
