DRUG CLASS AND MECHANSIM: Colchicine is an oral drug used for treating acute gout and familial Mediterranean fever (FMF). In acute gout there is severe inflammation in response to the presence of uric acid crystals that form in bony joints.This causes severe pain, redness, and swelling of the affected joint(s).RESCRIBED FOR: Colchicine is used for the treatment of acute flares of gout. It also is used for treating FMF in adults and children 4 years of age or older.
A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a blood gas analysis or arterial blood gas (ABG) test. Your red blood cells transport oxygen and carbon dioxide throughout your body. These are known as blood gases. As blood passes through your lungs, oxygen flows into the blood while carbon dioxide flows out of the blood into the lungs.
The PaO2, like I said, is the partial pressure of O2 in arterial blood-- typically measured via ABG. SaO2 doesn't measure tissue perfusion. It measures as a percentage the amount of hemoglobin molecules which are oxygenated (oxyhemoglobin) in arterial blood.PaO2 = measures oxygen in the blood (80-100).aO2 (and its indirect measurement SpO2) describe the amount of oxygen bound to hemoglobin in arterial blood. The term saturation likens hemoglobin to a sponge that becomes saturated with oxygen. The measurement is given as a percentage. PaO2 describes the amount of oxygen dissolved in arterial blood plasma.
