Arterial blood gases (ABGs) are routinely done in critical clinical settings to ascertain acid-base status. Due difficulties and the potential side effects following arterial sampling, much research has been find possibility of using venous samples as an alternative. However, this comparison needs be evaluated various contexts. Hence, systematic review aims explore differences, appropriateness,...

The arterial blood gas (ABG) is a frequently ordered laboratory test. Laboratory tests should be ordered to make accurate diagnoses, change management, monitor the response to management [1,2]. The continued frequency of ABG valuation may be influenced by routine work-patterns and easy access via arterial lines [3]. Many laboratory analysis including ABG are repeated too early [4].
