An embodiment for determining a blood-oxygen level (e.g., SpO2) of a subject includes exposing a body portion of the subject to more than two wavelengths of electromagnetic energy, receiving a portion of the more than two wavelengths redirected by the body portion, converting the received portion of the redirected more-than-two wavelengths into signals each representing a respective group of at least one of the more than two wavelengths, and determining the blood-oxygen level (e.g., SpO2) of the subject in response to the signals. For example, such an embodiment can determine the blood-oxygen level of the subject with little or no skin-tone bias. That is, such an embodiment can determine the blood-oxygen level of the subject independently of the subject's skin tone, i.e., with little or no skin-tone-induced corruption of the determined blood-oxygen level.

Existing pulse oximeters have impaired accuracy in measuring blood oxygen levels (SpO2) in patients of color, where the presence of melanin in the skin tends to interfere with measurements of pulse oximetry, resulting in an overestimation of SpO2. Thus, the pulse oximeter often reports a higher oxygen saturation for patients with darker skin tones, often with increasing bias as the actual saturation (SaO2) decreases. This bias is further reinforced by calibration based on individuals with light skin pigmentation, which may lead to inequitable healthcare for patients of color. Our proposed solution is to modify current pulse oximetry calculations—which utilize the relative tissue absorbance of red and infrared light to estimate SpO2—to account for the concentration of melanin by additionally measuring the skin absorbance of UV˜A light. This derived concentration of melanin can then be used to modify the pulse oximetry algorithm output, thus estimating SpO2 more accurately for patients of color.

A kit for creating and healing a simulated wound includes a fabric patch that can be saturated with a liquid to become translucent. The patch includes an image of a simulated wound, such as a cut, scratch, or abrasion. Water is applied to a person's skin. The patch is applied to the wetted skin and is saturated by the water, causing the fabric forming the patch to become translucent so that the color of the user's skin is at least partially visible through the patch. This creates the illusion that the simulated wound image is an actual injury. The kit also includes a simulated bandage. The bandage has a gripping portion, such as a patch of “hook” materials from a “hook-and-loop” fastener, on its bottom surface. When the gripping portion of the bandage is contacted with the patch, the gripping portion engages with the fabric so that when the bandage is pulled away from the skin, the patch and the simulated wound are also pulled away from the skin, creating the illusion that the wound has been healed.
