Embodiments of extremity supports comprise a stabilizer and at least one window. In one embodiment, the window is a transparent portion of the stabilizer. In another embodiment, the window is an opening in the extremity support. In yet another embodiment, a window is an area of the extremity support that does not impede a health care worker's view of the lower part of an extremity. ## Claims ### Claim 1 A method for assessing a patient's extremity for signs of infiltration and extravasation during peripheral intravenous (IV) therapy comprising: (a) locating a venipuncture site on the extremity of the patient; (b) affixing to the patient an extremity support at the venipuncture site on the extremity of the patient, wherein the extremity support comprises a stabilizer having (i) an upper portion, a middle portion and a lower portion, (ii) at least one window, and (iii) a first strap that is attached to the upper portion of the stabilizer and a second strap that is attached to the lower portion of the stabilizer; wherein the upper portion and the lower portion of the stabilizer are wider than the middle portion of the stabilizer; and wherein the stabilizer inhibits movement of the extremity and does not surround the extremity; (c) wrapping the first strap and the second strap around the extremity of the patient to secure the extremity support to the patient; and (d) palpating the extremity for signs of infiltration and extravasation during IV therapy without removing the extremity support. ### Claim 2 (depends on 1) The method of claim 1, wherein the extremity support comprises three straps. ### Claim 3 (depends on 1) The method of claim 1, wherein the stabilizer further comprises at least one slit to accommodate the first strap. ### Claim 4 (depends on 1) The method of claim 1, wherein the stabilizer further comprises at least one anchor; and wherein the first strap is affixed to the anchor. ### Claim 5 (depends on 1) The method of claim 1, wherein the extremity support is an arm support. ### Claim 6 (depends on 1) The method of claim 1, wherein the extremity support is a leg support. ### Claim 7 (depends on 1) The method of claim 1, wherein the stabilizer is transparent. ### Claim 8 (depends on 1) The method of claim 1, wherein the stabilizer is plastic. ### Claim 9 (depends on 1) The method of claim 1, wherein the stabilizer comprises at least two windows. ### Claim 10 (depends on 1) The method of claim 1, wherein the stabilizer further comprises ventilation holes. ### Claim 11 (depends on 1) The method of claim 1, wherein the stabilizer is contoured to fit a patient's extremity. ### Claim 12 (depends on 1) The method of claim 1, wherein the stabilizer further comprises padding. ### Claim 13 (depends on 1) The method of claim 1, wherein the first strap is mesh, cloth, stretch wrap, burn net, gauze, cotton cloth, or nylon. ### Claim 14 (depends on 1) The method of claim 1, wherein the first strap comprises elastic or silicon. ### Claim 15 (depends on 1) The method of claim 1, wherein the stabilizer further comprises at least one slit to accommodate the second strap. ### Claim 16 (depends on 1) The method of claim 1, wherein the stabilizer further comprises at least one anchor; and wherein the second strap is affixed to the anchor. ### Claim 17 (depends on 1) The method of claim 1, wherein the second strap is mesh, cloth, stretch wrap, burn net, gauze, cotton cloth, or nylon. ### Claim 18 (depends on 1) The method of claim 1, wherein the second strap comprises elastic or silicon. ### Claim 19 (depends on 1) The method of claim 1, wherein the stabilizer is in the shape of an hourglass.
