The normal range for ph is 7 35 7 45. An abg is performed and reveals the following.
Normal values for arterial blood gas abg normal values are given below.
Abg normal ranges. 7 49 7 35 7 45. Ph 7 35 acidemia ph 7 45 alkalemia. A ph of less than 7 0 is called acid and a ph higher than 7 0 is called basic alkaline.
The base excess indicates the amount of excess or insufficient level of bicarbonate in the system. As the ph decreases 7 35 it implies acidosis while if the ph increases 7 45 it implies alkalosis. An abg is performed on the patient who is not currently receiving any oxygen therapy.
An acidosis or alkalosis may be present even if the ph is in the normal range 7 35 7 45 you will need to check the paco 2 hco 3 and anion gap. A negative base excess indicates a base deficit in the blood. Normal reference range is between 5 to 3.
The ph of blood is usually between 7 35 and 7 45. In the context of arterial blood gases the most common occurrence will be that of respiratory acidosis. Abg value normal results range.
Be sure to know the normal ranges and units for the analyser you will be using. Oxygen saturation sao2 95 to 100. The ph measures hydrogen ions h in blood.
Note that these may vary slightly between analysers. This is particularly important if your patient is known to have chronic respiratory disease with existing chronic abg changes. This measures the pressure of co2 dissolved in the blood and how well carbon dioxide has the ability to move out of the body.
They have no significant past medical history and are not on any regular medication. Normal is considered to be from 22 to 26 mmol l. Partial pressure of oxygen pao2 75 to 100 millimeters of mercury mmhg partial pressure of carbon dioxide paco2 35 to 45 mmhg.
This is usually the primary disorder. The aforementioned components all have different normal values and represent different aspects of the blood gas. Is there alkalemia or acidemia present.
14 11 13 kpa 105 mmhg 82 5 97 5 mmhg ph. Bicarbonate hco3 22 to 26 milliequivalents per liter meq liter. Is the disturbance respiratory or metabolic.
According to the national institute of health typical normal values are. What is the relationship between the direction of. The normal range for paco2is 35 to 45 mmhg.
Finally bicarbonate ions or hco3 will tell you if the problem is related to metabolic changes in your patient and refers to the renal system berman et al.
