Abstract: Embodiments for intravenous extremity supports for pediatric and adult patients that allow health care workers to visually assess and/or palpate an extremity during IV therapy without removing the extremity support are disclosed. 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.
