2. Carbon dioxide molecule. pCO2, pCO2, or is the partial pressure of carbon dioxide (CO 2), often used in reference to blood but also used in meteorology, climate science, oceanography, and limnology to describe the fractional pressure of CO 2 as a function of its concentration in gas or dissolved phases. The units of p CO 2 are mmHg, atm ...

End tidal CO2 (PETCO2) MeSH. D019296. [edit on Wikidata] Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO. 2) in the respiratory gases. Its main development has been as a monitoring tool for use during anesthesia and intensive care. It is usually presented as a graph of CO.
The atmospheric pressure is roughly equal to the sum of partial pressures of constituent gases – oxygen, nitrogen, argon, water vapor, carbon dioxide, etc.. In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas as if it alone occupied the entire volume of the original mixture at the same temperature.

Arterial carbon dioxide partial pressure (P a CO 2) 4.7–6.0 kPa 35–45 mmHg [13] The carbon dioxide partial pressure (PaCO 2) is an indicator of CO 2 production and elimination: for a constant metabolic rate, the PaCO 2 is determined entirely by its elimination through ventilation. [14]
The carbon dioxide content of the blood is often given as the partial pressure, which is the pressure which carbon dioxide would have had if it alone occupied the volume. [73] In humans, the blood carbon dioxide contents are shown in the adjacent table.
Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. [1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with ...
In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. The concentration of carbon dioxide (CO 2) in the atmosphere reach 427 ppm (0.04%) in 2024. [1]
