CaO2 or âOxygen Contentâ gives a definite amount of ALL the oxygen in the blood. It is the only method that takes into account how much hemoglobin is actually present in the body and uses the PaO2 and SaO2 values to get the amount of oxygen. It uses the units âml O2/dlâ (milliliters of oxygen per deciliter of blood).
Cold & flu health centre. Bronchitis. Bronchitis is a common infection causing inflammation and irritation to the main airways of the lungs. Symptoms of bronchitis include coughing up yellow-grey mucus, sore throat, wheezing and having a blocked nose. Acute bronchitis may be responsible for the hacking cough and phlegm production that sometimes accompany an upper respiratory infection. In most cases, the infection is viral in origin, but sometimes it's caused by bacteria.

It is sometimes caused by other kinds of germs, such as bacteria (bak-TEE-ree-ah), yeast, or a fungus. 2  Acute bronchitis can be caused by breathing air that has chemical fumes, dust, or pollution. 3  Smoke, such as from a cigarette or a fire, may also cause bronchitis.
