  2. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [141] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

  3. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    Carbon dioxide has unique long-term effects on climate change that are nearly "irreversible" for a thousand years after emissions stop (zero further emissions). The greenhouse gases methane and nitrous oxide do not persist over time in the same way as carbon dioxide. Even if human carbon dioxide emissions were to completely cease, atmospheric ...

  4. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–oxygen_bond

    A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [ 1 ] [ 2 ] [ 3 ] : 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides , carbonates and metal carbonyls , [ 4 ] and in organic compounds such as alcohols , ethers , and carbonyl compounds .

  7. Respiratory quotient - Wikipedia

    en.wikipedia.org/wiki/Respiratory_quotient

    The respiratory exchange ratio (RER) is the ratio between the metabolic production of carbon dioxide (CO 2) and the uptake of oxygen (O 2). [3] [4] The ratio is determined by comparing exhaled gases to room air. Measuring this ratio is equal to RQ only at rest or during mild to moderate aerobic exercise without the accumulation of lactate.

  8. Pulmonary gas pressures - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_gas_pressures

    The alveolar oxygen partial pressure is lower than the atmospheric O 2 partial pressure for two reasons.. Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg.

  9. Blood gas tension - Wikipedia

    en.wikipedia.org/wiki/Blood_gas_tension

    Carbon dioxide is a by-product of food metabolism and in high amounts has toxic effects including: dyspnea, acidosis and altered consciousness. [8] Arterial blood carbon dioxide tension. P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 mmHg and 45 mmHg. [9] Venous blood carbon dioxide tension
