WCN25-996 CORRELATION OF VENOUS BLOOD GAS WITH ARTERIAL BLOOD GAS VALUES IN PATIENTS ADMITTED TO EMERGENCY DEPARTMENT

ABG is of utmost value for monitoring and driving the management of patients with multiple diseases. Though extremely useful, it has its own limitations and adverse effects like increased risk of errors in sample collection, over or under heparinization, mixing of venous blood, and delay in analysing. Drawing arterial blood is a very painful procedure and can be an issue in critically ill patients who have to undergo repeated procedures. Indwelling arterial catheters may cause bloodstream infections, local thrombosis, arterial vasospasm, aneurysm formation and rarely, thrombosis of radial artery leading to ischemia.
