Section 1.1: Light Sensitivity in Medical Devices

Light plays a crucial role in the functionality of medical equipment, which can lead to performance disparities across different demographics. For instance, laser hair removal technology is most effective on individuals with dark hair and light skin due to the contrast, while it struggles with lighter hair colors.

According to the Cleveland Clinic, “Laser hair removal is most effective for people with thick, dark hair and light skin. The contrast between skin color and hair color makes it easier for the hair to absorb heat.” This reality can leave individuals feeling disheartened, as they may have invested in a service that does not yield the desired results. Alternatives like shaving or waxing exist, but the issue highlights a broader concern regarding device biases.

Section 1.2: The Focus on the Black Community

Recent studies have increasingly examined the biases affecting the Black community in healthcare settings. This focus is vital, as the prejudices inherent in medical technology can significantly hinder timely treatment for serious health conditions.

A study revealed that forehead thermometers were less accurate for individuals with darker skin tones. Similarly, pulse oximeters—small devices used to measure blood oxygen levels—have demonstrated reduced accuracy in people of color. These inaccuracies can pose serious risks, particularly if these are the only diagnostic tools available in smaller medical facilities.

Section 1.3: The Consequences of Inaccurate Readings

Consider the implications of relying on inaccurate devices. The potential for missed early detection is alarming, especially since health campaigns emphasize that early diagnosis can save lives.

Research on forehead thermometers highlighted discrepancies in fever detection among different racial groups. For instance, the rate of fever detected in Black patients was reported at 10.1% using temporal thermometers, compared to 13.2% with oral thermometers. In contrast, the figures for White patients were 10.8% and 10.2%, respectively.

The ramifications of such inaccuracies can be dire. Delayed treatments, unrecognized symptoms, and ultimately, a heightened risk of severe health consequences occur when individuals do not receive timely and accurate care.

Section 1.4: Everyday Health Tools

The bias in medical technology extends beyond clinical settings. Everyday health tools can also disadvantage Black individuals. For example, certain automatic soap dispensers and faucets may fail to recognize darker skin tones, leading to frustrating experiences in public restrooms.

Electrical engineer Achuta Kadambi shared a personal anecdote, stating, “Being fairly dark-skinned myself, I sometimes cannot activate no-touch soap dispensers and faucets that detect light bouncing off the skin.” Such encounters underscore the everyday challenges faced due to technological biases.

Section 1.5: The Importance of Advocacy

The stories of people of color waiting longer for medical treatment often stem from the failure of machines to accurately reflect their symptoms and concerns. This reality underscores the necessity for individuals to advocate for themselves and others within marginalized communities.
