Analysis Blood Gas

Analysis blood gas. Bicarbonate using the ph co 2 and the henderson hasselbalch equation. 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. When interpreting arterial blood gas abg results it is essential to know what abg values are considered normal. Purpose an abg analysis evaluates how effectively the lungs are delivering oxygen to the blood and how efficiently they are.

Definition blood gas analysis also called arterial blood gas abg analysis is a test which measures the amounts of oxygen and carbon dioxide in the blood as well as the acidity ph of the blood. Your red blood cells transport oxygen and carbon dioxide throughout your body. This test measures the partial levels of these substances using a small blood sample. From this baseline you can then begin to recognise significant variations in a patient s results which could indicate clinical deterioration.

Doctors often use the test in. These are known as blood gases. Arterial blood for blood gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist a nurse a paramedic or a doctor. Learn about the interplay between blood gas and acid base analysis and how carbon dioxide affects arterial ph.

Master arterial blood gas analysis based on an understanding of relevant physiologic principles. The test is commonly known as a blood gas analysis or arterial blood gas abg test. Arterial blood gas analysis is used to measure the ph and the partial pressures of oxygen and carbon dioxide in arterial blood. The source of blood is an artery unlike the routine blood tests which involve withdrawing blood from a vein.

The investigation is relatively easy to perform and yields information that can guide the management of acute and chronic illnesses this information indicates a patient s acid base balance the effectiveness of their gas exchange and the state of their ventilatory. Arterial blood gas abg analysis is a blood test which measures the acidity ph and the levels of oxygen and carbon dioxide in the blood. Blood gas machines directly measure three variables and calculate the remainder. A blood gas test is also called an arterial blood gas test or a blood gas analysis.
