How To Write A Laboratory Blood Gas Analysis

The test that were conducted on J.T. were a laboratory blood test, pulse oximetry test, an arterial blood gas analysis, a pulmonary function test, and a chest x-ray. The laboratory blood test may not directly tell if a person has COPD but they are important to note the possible causes of one’s symptoms and are useful for ruling out other disorders. A laboratory blood test also includes an arterial blood gas analysis which is useful to determine if one’s lungs are working properly and begs to answer the question: is one bringing in adequate oxygen and getting rid of carbon dioxide? A pulse oximetry test is useful to see how well oxygenated your blood is. Moreover, the pulmonary function test measure ventilation or the amount of air one can take
With a laboratory blood test, your healthcare provider can assess any deviations in your lab values such as your serum electrolytes which is useful in determine potential causes and ruling out others for COPD and the arterial blood gas analysis is useful because your healthcare provider can see your oxygen and carbon dioxide levels in your blood. If your oxygen levels in your blood plasma are not in the normal range this means your body is not receiving enough oxygen and this is useful in diagnosing COPD. Conversely if your blood carbon dioxide levels are high, this would mean that your body is doing a poor job of excreting carbon dioxide which is also an important detection as well. Pulse oximetry test are another way to measure oxygenation in the blood. Pulse oximetry tells the percent of oxygen that a person’s body is able to carry. If this number is low that could mean that the person is hypoxic and is a common feature of COPD. Moreover, pulmonary function test measures the lung capacity and functioning of your lungs. One pulmonary function test that is particularly useful for people with COPD and for diagnosing COPD is spirometry. When testing for COPD two values are important: the FVC (forced vital capacity) and FEVC1 (forced expiratory volume). The FVC measures your lung capacity or the maximum amount of air you can exhale after taking a full inhale, while the FEV1 measures the amount of air that can be exhaled forcefully after one second. These baseline measures for these numbers depend on different factors such as your age and height. It has been shown that the FEV1/FVC ratio is less than 70% in people with COPD and the FEV1 percentage predicted shows the severity of the obstruction. Lower than 80% is considered moderate COPD, and below 50% of is severe. Last, chest X-rays often show whether a person has emphysema, a condition associated with COPD, and can be detected as
