Why is a tourniquet not used when collecting arterial blood gases?
may compromise the sample
may elevations in potassium sample
arterial blood is under pressure

ulnar pulse rate synchronizes with the radial pulse
pulse rate increases in the radial artery
color appears in the hand within 5 to 10 seconds
