“Life isn't just about taking in oxygen and giving out carbon dioxide.”

Carbon dioxide (CO 2) is an odorless colorless gas. It is a waste made by your body. Your blood carries carbon dioxide to your lungs. You inhale carbon dioxide every day and inhale oxygen without having to think about it. CO2 blood test measures the amount of carbon dioxide in the blood. If the amount of carbon dioxide in the blood is too much or too little, there is a possibility of a health problem. Carbon dioxide blood test is often part of a series of tests called electrolyte panels. The electrolyte helps to balance the acid and alkali content in the body. Most of the carbon dioxide in your body is bicarbonate, which is an electrolyte. The electrolyte sheet can be part of daily inspection. This test can also help monitor or diagnose conditions related to electrolyte imbalance. These include kidney disease, pulmonary disease and hypertension

Blood oxygen analysis, also known as blood gas analysis, measures the amount of oxygen and carbon dioxide in the blood. When you breathe, your lungs inhale oxygen (inhale) and spit out carbon dioxide (spit out). If the concentration of oxygen and carbon dioxide in the blood is not well balanced, there is a possibility that the lungs are not functioning properly. Most blood tests are done from veins. In this test, health care providers collect blood samples from arteries. That is because oxygen from the artery is higher than venous blood. Samples are usually taken from the artery of the wrist. This is called radial artery. Samples may be taken from the arteries of the elbow or groin. If you are testing newborn babies, you can sample it from your baby's heel or umbilical cord
