The device was medical grade and measured heart rate and blood oxygen levels, similar to a pulse oximeter. The wearable device was battery powered and each one connected to a tablet that was kept at the patients’ bedside. The tablets had a 3 G or 4 G sim card and sent the data to a cloud where multiple patients’ data were viewable by HCWs outside the patients’ rooms and isolation area.

The Avoximeter 4000 is a blood oximeter that performs hemoglobin, O2 Hb, COHb, and methemoglobin direct measurements on blood samples of about 50 µL by analyzing light absorption at 5 different wavelengths. The drawn blood is injected into a single-use cuvette, which is inserted into the device. Results are delivered in 7 to 10 seconds. This device can easily be transported by virtue of its reasonable size (20.3 cm×25.4 cm×9.5 cm) and weight (1.8 kg).

In this paper, we prove the following three hypotheses: (1) skin tone has a significant effect on pulse oximeter measurements (hypothesis 1), (2) images of skin tone can be used to calibrate for pulse oximeter error (hypothesis 2), and (3) Sp O2 can be measured with a smartphone camera using the screen as a light source (hypothesis 3).
Through quantitative analysis, we demonstrate how skin tone affects pulse oximeters.

Oxygen saturation, defined as the fraction of oxygen-saturated hemoglobin relative to total blood hemoglobin, is measured either through an invasive method by sampling arterial blood to analyze the arterial oxygen saturation (Sa O2) via a co-oximeter or with readings collected noninvasively using a pulse oximeter to measure the peripheral or pulse oxygen saturation (Sp O2) level [10].
