A semiquantitative assessment of the degree of pallor also may be helpful. While the patient is supine, the degree of pallor is assessed. If pallor manifests when the extremity is level, the pallor is classified as level 4. If not, the extremity is raised 60°. If pallor occurs in 30 seconds or less, it is a level 3; if in less than 60 seconds, level 2; and if in 60 seconds, level 1. If no pallor occurs within 60 seconds, it is level 0.
