Blood Gases Analysis
The most common acid base imbalance seen in the paediatric population is a metabolic acidosis secondary to infections catabolic states or severe dehydration.
Blood gases analysis. 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. 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. Your red blood cells transport oxygen and carbon dioxide throughout your body. Master arterial blood gas analysis based on an understanding of relevant physiologic principles.
This test measures the partial levels of these substances using a small blood sample. The test is commonly known as a blood gas analysis or arterial blood gas abg test. Learn about the interplay between blood gas and acid base analysis and how carbon dioxide affects arterial ph. From this baseline you can then begin to recognise significant variations in a patient s results which could indicate clinical deterioration.
These are known as blood gases. Results show blood oxygen and carbon dioxide levels ph levels and lung function. Arterial blood gas analysis can be used to assess gas exchange and acid base status as well as to provide immediate information about electrolytes. Arterial blood gas abg analysis informs the physician about the activity of two systems the.
A blood gas test is also called an arterial blood gas test or a blood gas analysis. 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. Doctors often use the test in. It is also useful to have access to any previous gases.
Blood gas analysis is a key investigation in a patient with a suspected imd particularly during acute episodes of illness. Arterial blood for blood gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist a nurse a paramedic or a doctor. You ll cover crucial factors that determine oxygenation of blood in the lungs and oxygen transport and delivery to peripheral tissues. The source of blood is an artery unlike the routine blood tests which involve withdrawing blood from a vein.
Arterial blood gas analysis is used to measure the ph and the partial pressures of oxygen and carbon dioxide in arterial blood.
