General Information about CO2

Carbon dioxide is the combination of two atoms of oxygen joined with a single atom of carbon. Its chemical formula CO 2, is almost as well-known as that of water, H 2 O, and it is frequently referred to by its formula rather than its name. In nature’s chain of life, the mutual dependence of plant and animal life is maintained through the link of carbon dioxide.

CO2 Gas Concentration Defined |

When measuring gases like carbon dioxide, oxygen, or methane, the term concentration is used to describe the amount of gas by volume in the air. The 2 most common units of measurement are parts-per-million, and percent concentration. Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 ...

Pulse Oximetry > Fact Sheets > Yale Medicine

Pulse oximetry offers many advantages over traditional methods of measuring blood oxygen levels. Whereas traditional methods usually involve drawing a sample of arterial blood—a potentially painful experience for patients that requires around 15 minutes, at minimum, to analyze blood samples—pulse oximetry is noninvasive and provides near-immediate readings.
