Studies suggest that SpO2/FiO2 and PaO2/FiO2 ratios are reasonably well correlated, particularly when PaO2/FiO2 ratios are less than 300, 18 – 22 and ARDS mortality and ventilator days are similar when disease severity is defined by SpO2/FiO2 ratios. These issues could be addressed through use of pulse oximetry-based peripheral blood oxygen saturation (SpO 2)/FiO 2 (SpO 2/FiO 2) ratios, which are ubiquitously available and noninvasive. 2 These studies highlight the need for more readily available severity classification methods to facilitate early recognition, phenotyping, and assessment of therapeutic response in both patients with ARDS AHRF and patients with non-ARDS AHRF. Furthermore, there is a surprising paucity of information regarding severity of illness classification and risk stratification in patients with non-ARDS AHRF, and recent work suggests mortality rates may be comparable in patients with ARDS and non-ARDS AHRF, with similar degrees of hypoxemia. 5, 14 – 17 However, the absence of standardized practices regarding ABG use and the increasing focus on early identification and treatment of patients with AHRF limit the utility of ABG-based, reactive evaluation strategies. Several studies suggest that repeated measurements of the PaO2/FiO2 ratio 24 or more hours after ARDS onset may improve the accuracy of classification and prognosis. German doctors are currently using the wearable as a cheap way to monitor COVID-19 patients, for example.Inconsistent use of PaO2/FiO2 ratios may be a barrier to AHRF classification and prognostication. (According to Withings, the ScanWatch is so good that it’s utilized in some medical settings. smartwatch market, as it’s a certified medical device. It’s an incredibly unique product in the U.S. Of course, this makes ScanWatch the first wearable to get FDA approval for ECG and SpO2-based health detection features. While other smartwatches have ECG and SpO2 sensors, they don’t claim to detect atrial fibrillation or breathing disturbances so they can skip the FDA. release is a result of the FDA approval process, which is required for any product that claims to detect medical conditions. First, the ScanWatch actually launched last year in Europe and Australia. There’s a few things that we need to clarify up front. with FDA approval for its unique health monitoring features. And after what seems like a lifetime (I can’t remember January 2020 at all), the ScanWatch is finally available in the U.S. During CES 2020, we found ourselves drawn to the Withings ScanWatch, a stylish wearable with SpO2 sensors and advanced algorithms.
