[ correlation between arterial blood gases and venous blood gases among the mechanically ventilated patients admitted in intensive care unit]

ABSTRACT

Background: While the arteriopuncture is a painful and relatively risky procedure and may be complicated by some problems, venopuncture required for assessing the venous blood gases [VBG] is an easier procedure with fewer complications. Considering the mentioned notion, substituting the VBG values for of ABG values can prevent such complications. This study was carried out with the aim of determining whether the VBG values can be replaced for ABG values in the management of mechanically ventilated patients admitted in ICU wards
