Abstract
A pulse-oximeter photoplethysmographic sensor unit that includes a light source and a deformable pressure reducing relief layer. The pressure relief layer is disposed proximate to the light source between a subject's extremity and the light source. The relief layer is translucent to the light from the light source. The deformable relief layer is a removable, disposable gel pad attachable to the light source and may include opaque side walls increasing light transmission while reducing ambient light transmission. The relief layer may have an index of refraction between the index of refraction of the light source and that of a subject's extremity. The pulse-oximeter sensor unit may have an attachment mechanism such as a spring biased clam-shell clamp or a wrap around strip.
