Introduction
A female patient is brought into the emergency room. She is complaining of shortness of breath and extreme difficulty in breathing after a vigorous run. Suspecting respiratory acidosis, a condition in which the blood pH is too acidic, the emergency room doctor orders a blood gas test.
What is blood gas? A blood gas is exactly that...it measures the dissolved gases in your bloodstream. This provides one of the best measurements of what is known as the acid-base balance. The body is an active chemical reaction, requiring a precise balance of the acids and bases, a measurement known as pH. The normal pH is 7.40. There are four parameters which are measured: Oxygen (O2), Carbon Dioxide (CO2), Bicarbonate (HCO3-), and pH (Reece, 2002).
Many people today exercise as a way of improving their health and physical abilities. When we exercise, our heart rate, systolic blood pressure, and cardiac output (the amount of blood pumped per heart beat) all increase. Blood flow to the heart, the muscles, and the skin increase. The body's metabolism becomes more active, producing increased levels of carbon dioxide (CO2) and hydrogen ions (H+) in the muscles. This metabolism is cellular respiration (Silverthorn, 2002).
Cellular Respiration is the process used by living cells to break down sugar molecules (glucose) that living things get when eating plants or animals. This breakdown involves oxygen and results in the production of energy, carbon dioxide and water: Glucose + oxygen --> CO2 + H2O + ATP (energy) (Silverthorn, 2004). ATP is used as our energy source; however, CO2 is a byproduct and must be removed from the body. When CO2 mixes with water in the interstitial fluid, the reaction is carbonic acid (H2CO3). Additionally, carbonic acid breaks apart into bicarbonate (HCO3-) and H+. It is the free H+ that lowers the pH level, thus lead to the disruption of the acid-base balance. Fortunately the body has a...
