SpO2 is the saturation of oxygen in the blood as measured by a pulse oximeter. A pulse oximeter is non-invasive and measures the SpO2 through the capillary bed, often at a fingertip. This is different from SaO2, which measures the oxygen saturation of arterial blood and requires blood sampling.
The "O2" in SpO2 stands for the two atoms of oxygen that make up an oxygen molecule. The "S" stands for the saturation of hemoglobin in the blood, or the percentage of hemoglobin, which carries oxygen. The "p" stands for the pulse, which differentiates SpO2 from the SaO2 laboratory blood test.Learn More
SN2 reactions are organic chemistry reactions in which an ion called the nucleophile attacks the center of another molecule and replaces one of the ions, called the leaving group. These types of reactions are called nucleophilic substitution reactions, and there are two types, SN1 and SN2. SN1 reactions occur in two steps, but SN2 reactions occur in a single step.Full Answer >
SO2, commonly known as sulfur dioxide, has an sp3 hybridization. The molecular geometry of sulfur dioxide consists of two oxygen atoms bonded to the central sulfur atom.Full Answer >
The chemical formula Al2(CO3)3 refers to the chemical aluminum carbonate. This chemical compound of aluminum, carbon and oxygen is unstable and rapidly decomposes to aluminum hydroxide and carbon dioxide.Full Answer >
The name for the compound having the chemical formula H2CO3 is carbonic acid. It is formed from the reaction of carbon dioxide with water. Conversely, carbonic acid also disintegrates to produce carbon dioxide and water, which makes the reaction balanced, or in a state of equilibrium.Full Answer >
