Blood Gas Analysis Normal Range

Blood gas analysis normal range. Your red blood cells transport oxygen and carbon dioxide throughout your body. Some abg results also show hemoglobin and serum electrolyte values. 4 5 6kpa base excess be. Normal values for ph range from 7 35 7 45.

This will determine if the changes in the blood gas are due to the respiratory system or metabolically driven. The test is commonly known as a blood gas analysis or arterial blood gas abg test. A normal reference range is 5 15 mmhg. The normal range for ph is 7 35 7 45.

Blood gas analysis cannot be used as a screening test for early pulmonary disease. 10 14kpa pco2. Blood ph has to be maintained within a tight normal range to avoid cellular death. These are known as blood gases.

80 100 millimeters of mercury mmhg partial pressure of carbon dioxide. Arterial blood gas test normal values shows values for ph oxygen carbon dioxide bicarbonates lactic acid levels and oxygen saturation. Arterial blood gas is usually advised to patients suffering from respiratory illnesses or under critical care. This can be achieved by buffer mechanisms which can be either renal or respiratory in nature.

The following are normal ranges for results of a blood gas test. Normal values for arterial blood gas abg normal values are given below. In the context of arterial blood gases the most common occurrence will be that of respiratory acidosis. Carbon dioxide is dissolved in the blood as carbonic acid a weak acid.

However in large. 2 2 mmol l. The difference expressed as p a a o 2 increases with age cigarette smoking and increasing fio 2. Acidosis is an abnormal process that increases the serum hydrogen ion concentration lowers the ph and results in acidaemia.

In combination with the hco3 the nurse will be able to fully comprehend the blood gas. As the ph decreases 7 35 it implies acidosis while if the ph increases 7 45 it implies alkalosis. Be sure to know the normal ranges and units for the analyser you will be using. This determines if the blood is acidotic or alkalotic.

Metabolic problems will require respiratory compensation and this occurs rapidly eg by increasing ventilation to blow off co 2 on the other hand respiratory problems leading to acid base abnormalities. 22 26 mmol l. 80 100 mmhg 10 6 13 3 kpa determine ph status. The next value is the carbon dioxide level and this will tell you if the problem is respiratory in origin as co 2 is regulated by the lungs berman et al.

Severe disease may be present before significant changes are seen in blood gases. And even with a normal ph level acidosis or alkalosis may still be present as the body can compensate to balance the ph next examine the paco2.
