The health care provider may test circulation to the hand before taking a sample of blood from the wrist area the provider inserts a small needle through the skin into the artery the sample is quickly sent to a laboratory for analysis. Arterial blood gas (abg) analysis is an essential part of diagnosing and managing a patient's oxygenation status and acid-base balance the usefulness of this diagnostic tool is dependent on being able to correctly interpret the results. A blood gas test measures the amount of oxygen and carbon dioxide in the blood it may also be used to determine the ph of the blood, or how acidic it is the test is commonly known as a blood gas.
Arterial whole blood is almost always used for blood gas analysis but, in some cases, as with babies, whole blood from a heelstick is collected instead blood may also be taken from the umbilical cord of a newborn. An arterial blood gas (abg) test measures oxygen and carbon dioxide levels in your bloodit also measures your body's acid-base (ph) level, which is normally balanced when you are healthy. Arterial blood gas analysis is a common investigation in emergency departments and intensive care units for monitoring patients with acute respiratory failure. Arterial blood gases (abgs) are an important routine investigation to monitor the acid-base balance of patients  they may help make a diagnosis, indicate the severity of a condition and help to assess treatment.
Arterial blood for blood-gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist, a nurse, a paramedic or a doctor blood is most commonly drawn from the radial artery because it is easily accessible, can be compressed to control bleeding, and has less risk for occlusion. The blood gas analysis cannot yield a specific diagnosis a patient with asthma may have similar values to another patient with pneumonia alternatively, a patient with chronic obstructive pulmonary disease and respiratory failure may have similar results to a patient with pulmonary oedema.
The arterial blood gas analysis, obtained while the patient is breathing a known fraction of inspired oxygen (f io 2), is the gold standard for assessing oxygenation, ventilation, and acid-base status. Find your blood gas analyzer easily amongst the 50 products from the leading brands (radiometer, roche, nova biomedical, ) on medicalexpo, the medical equipment specialist for your professional purchases. How to interpret blood gas results two methods: reviewing your test results closely considering other data community q&a your doctor may run a blood gas analysis or arterial blood gas (abg) test if you are showing the signs of an oxygen, carbon dioxide, or ph imbalance such as confusion or difficulty breathing. Arterial blood gas analysis is an important routine investigation to monitor the acid-base balance of patients, effectiveness of gas exchange, and the state of their voluntary respiratory control.
Interpreting an arterial blood gas (abg) is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel abg interpretation is especially important in critically ill patients. Blood gas analysis provides information on a critically ill patient's respiratory and metabolic status via measurement of ph, carbon dioxide (pco 2) and oxygen (po 2) together with other vital information such as electrolytes, lactate and hemoglobin. Blood gas testing the right solution whether you run one test per day or 100 - in the lab or at the point of care radiometer offers you a wide selection of blood gas analyzers with features and functionality that match your facility's needs.
Arterial blood gas analysis can be used to assess gas exchange and acid base status as well as to provide immediate information about electrolytes it is also useful to have access to any previous gases. Blood gas analysis gives a snapshot of a person's blood ph, o2 and co2 content the following components are generally included in blood gas analysis: ph-a measure of the balance of acids and bases in the blood. Abg analysis can be easy test your knowledge on the web's most interactive blood gas learning tool.
