Blood Gas Analysis Normal Values
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.
Blood gas analysis normal values. A normal pao 2 in a patient on high flow oxygen. This is abnormal as you would expect the patient to have a pao 2 well above the normal range with this level of oxygen therapy. This is particularly important if your patient is known to have chronic respiratory disease with existing chronic abg changes. 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. A normal paco 2 in a hypoxic asthmatic patient. Arterial blood gas is usually advised to patients suffering from respiratory illnesses or under critical care. The normal range for p a co 2 is 35 to 45 mmhg.
Results show blood oxygen and carbon dioxide levels ph levels and lung function. By kemal gunaydin introduction measurements of pao2 paco2 sao2 ph and bicarbonate values are made with arterial blood gas abg analysis in order to determine the acid base balance and respiratory regulation. In combination with the hco3 the nurse will be able to fully comprehend the blood gas. This determines if the blood is acidotic or alkalotic.
What does the arterial blood gas analysis measure. Instead it provides the values of the following five parameters. A sign they are tiring and need itu intervention. A blood gas test is also called an arterial blood gas test or a blood gas analysis.
The partial pressure of oxygen it is the pressure of oxygen in the arterial blood dissolved in plasma and is denoted by p02. 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. Arterial blood gas abg analysis is an important laboratory method that provides reliable information about the patient s metabolic status and respiratory physiology. Some abg results also show hemoglobin and serum electrolyte values.
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 vascular occlusion the selection of which radial artery to draw from is based on the outcome of an allen. Normal values for arterial blood gas abg normal values are given below. An arterial blood gas or abg for short is a test that measures the blood levels of oxygen pao2 carbon dioxide paco2 and acid base balance ph in the body the test results are used by medical professionals to assess how well oxygen is being distributed throughout the body and how well carbon dioxide is being removed. Be sure to know the normal ranges and units for the analyser you will be using.
Arterial blood gas analysis is not interpreted as positive or negative or as high or low. Note that these may vary slightly between analysers.
