Design outcomes

Primary

MeasureTime frame
To compare the first pass success rate in anatomical snuff box arterial sampling with conventional distal forearm among patients requiring arterial blood gas analysis in emergency departmentTimepoint: Till blood sample is obtained—

Secondary

MeasureTime frame
1.To compare the number of attempts between anatomical snuff box with distal forearm access in patients requiring arterial blood gas in emergency department. 2.To Compare the diameter and depth of radial artery from skin at anatomical snuff box radial artery access site with distal forearm radial artery access site using ultrasonography. 3. To compare the failure rate (after maximum 3 attempts) between anatomical snuff box access with distal forearm access in patients requiring arterial blood gas in emergency department. 4.To compare the complications between anatomical snuff box radial artery access with distal radial artery access in patients undergoing arterial blood gas in the emergency department. Timepoint: 12 hours after the sampling—
