It is well known that diabetes manifests into several complications for people who have heart failure, kidneyfailure,uncontrolled diabetes, sleep disorders, severe infections, or after a drug overdose.
Ordinarily, to control blood sugar levels, doctors suggest tests such as lipid profile, fasting pp blood sugar and HbAIC tests .and prescribe medication, diet and exercise.
Ina few cases where complication has already setin, it may not be possible control to optimum level of blood sugar level and it may go haywire and cause deterioration in health. In such cases expert docrors advise special diagnostic tests to find out why.
One such test is ABG test (Arterial bloodgas test
An arterial blood gas (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. This test is used to check how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood.
As blood passes through your lungs, oxygen moves into the blood while carbon dioxide moves out of the blood into the lungs. An ABG test uses blood drawn from an artery, where the oxygen and carbon dioxide levels can be measured before they enter body tissues. An ABG measures:
•Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood and how well oxygen is able to move from the airspace of the lungs into the blood.
•Partial pressure of carbon dioxide (PaCO2). This measures the pressure of carbon dioxide dissolved in the blood and how well carbon dioxide is able to move out of the body.
•pH. The pH measures hydrogen ions (H+) in blood. The pH of blood is usually between 7.35 and 7.45. A pH of less than 7.0 is called acid and a pH greater than 7.0 is called basic (alkaline). So blood is slightly basic.
•Bicarbonate (HCO3). Bicarbonate is a chemical (buffer) that keeps the pH of blood from becoming too acidic or too basic.
•Oxygen content (O2CT) and oxygen saturation (O2Sat) values. O2 content measures the amount of oxygen in the blood. Oxygen saturation measures how much of the hemoglobin in the red blood cells is carrying oxygen (O2).
Blood for an ABG test is taken from an artery. Most other blood tests are done on a sample of blood taken from a vein, after the blood has already passed through the body's tissues where the oxygen is used up and carbon dioxide is produced.
An arterial blood gas (ABG) test is done to:
•Check for severe breathing problems and lung diseases, such as asthma, cystic fibrosis, or chronic obstructive pulmonary disease (COPD).
•See how well treatment for lung diseases is working.
•Find out if you need extra oxygen or help with breathing (mechanical ventilation).
•Find out if you are receiving the right amount of oxygen when you are using oxygen in the hospital.
•Measure the acid-base level in the blood of people who have heart failure, kidney failure, uncontrolled diabetes, sleep disorders, severe infections, or after a drug overdose.
