Blood gas analysis is generally done to check the function of the lung organ that is the place where red blood cells carry oxygen and carbon dioxide from and to the whole body. In addition, this test can be done to check the condition of the heart and kidneys, as well as symptoms caused by disruption of oxygen distribution and carbon dioxide, or pH balance in the blood, such as nausea, shortness of breath, and decreased consciousness. This test is also performed on patients who are using a breath aid to monitor its effectiveness. Do you plan to find out the best finger oximeters for blood gas check needs?
Blood gas analysis is carried out to measure the acid-base level (pH) to find out if the blood is too acidic (acidosis) or alkaline (alkalosis), and to find out whether the oxygen pressure in the blood is too low (hypoxia), or carbon dioxide is too high (hypercarbia). These conditions can be related to the body’s metabolic system or respiratory system.
There is no special preparation that the patient needs to do before undergoing a blood gas analysis. The doctor or nurse will do an Allen test or check the smooth flow of blood vessels by pressing the blood vessels on the wrist for a few seconds.
If the patient is being given additional oxygen, the doctor will release the oxygen hose for about 20 minutes before performing a blood gas analysis test. However, this can be done if the patient is not completely dependent on the additional oxygen. For certain conditions, the doctor will give a local anesthetic to relieve pain that can occur when the needle is inserted into an artery.
After a blood gas test, the patient will feel pain and discomfort when taking blood for a few minutes afterward, because the arteries are sensitive enough. Patients are advised not to immediately leave the room to monitor things that might occur, such as dizziness, nausea, or fainting immediately after blood is taken.
Usually, patients can receive the test results about 15 minutes after blood collection. If further analysis is needed, results will be given to referring doctors.
