Health Monitoring Devices

The intent of the study was to determine the influence of skin type and wavelength on light reflectance for pulse rate detection. PPG sensors detecting changes in blood flow are assessed for effectiveness on dark and light skin tones. Studies have shown that green light lacks precision and accuracy, and may not read at all […]

The ability to measure physical activity through wrist-worn devices provides an opportunity for cardiovascular medicine. However, the accuracy of commercial devices is largely unknown. The aim of this work is to assess the accuracy of seven commercially available wrist-worn devices in estimating hea… This research paper assesses the accuracy of seven commercially available wrist-worn devices, […]

Medical devices employing AI stand to benefit everyone in society, but if left unchecked, the technologies could unintentionally perpetuate sex, gender and race biases. Medical devices utilising AI technologies stand to reduce general biases in the health care system, however, if left unchecked, the technologies could unintentionally perpetuate sex, gender, and race biases. The AI […]

Many devices and treatments work less well for them This article explores how the pulse oximeter, a device used to test oxygen levels in blood for coronavirus patients, exhibits racial bias. Medical journals give evidence that pulse oximeters overestimated blood-oxygen saturation more frequently in black people than white.

Pulse oximeters give biased results for people with darker skin. The consequences could be serious. COVID-19 care has brought the pulse oximeter to the home, it’s a medical device that helps to understand your oxygen saturation levels. This article examines research that shows oximetry’s racial bias. Oximeters have been calibrated, tested and developed using light-skinned […]

But what do we do when we discover […]

Many popular wearable heart rate trackers rely on technology that could be less accurate for consumers who have darker skin, researchers, engineers and other experts told STAT. An estimated 40 million people in the US alone have smartwatches or fitness trackers that can monitor heartbeats. However, some people of colour may be at risk of […]

Consumer wearables are devices used for tracking activity, sleep, and other health-related outcomes (e.g. Apple Watch, Fitbit, Samsung, Basis, Mio, PulseOn, Who Consumer wearables are devices used for tracking activity, sleep and other health-related outcomes, intended to help people reach their wellness goals. However these wearables are less accurate for people with darker skin tones, […]
