Study of Normal Arterial Blood Gas Parameters in Sari , Iran

It is very important to know about ABG in order to evaluate the oxygenation potency of lungs especially in critically ill patients - Many factors such as geographical position do affect ABG . This cross-sectional study was done on 83 healthy young persons having no systemic or other kinds of diseases affecting arterial blood gases . Information on PH , Pao2 , ao2 , Spo2 and Spo2 were gathered from each person . The obtained results were statistically analyzed using t-test . The mean Pao2 and Paco2 were 111.77 and 41.49 mmHg respectively (see also tables) . In the present study , special geographical position of Sari in the vicinity of the Caspian Sea, has affected the abovementioned parameters , so that pao2 is much higher . Therefore , higher levels of arterial oxygen is to be considered hypoxia in order to prevent the hypoxia risk .
