This is a cross-sectional diagnostic study. In this study, wrist oxygen saturation (SwO2) will be measured by Huami smart wearable device, SpO2 of pulse oxygen saturation monitor with medical device registration certificate and SaO2 of arterial blood gas analysis will be used as reference values. A total of 180 group data will be measured in 30~50 patients with SaO2/ SpO2 between 80%∽100%. The investigators aim to evaluate the accuracy of blood oxygen saturation detection function of huami smart wearable device.

Primary | Wearable device oximetry accuracy Arms | Record the pulse oximetry and pulse rate values measured at the same time by the medical monitor and the Huami Smart Wearable Pulse Oximetry Device, respectively. After an interval of 30 seconds, repeat the above steps to start the second measurement and record the measured value. After an interval of 30 seconds, repeat the above steps to start the third measurement and record the measured value. The average of three measurements was taken as data for the test group. Pulse oximetry monitor/desktop ECG monitor with a medical device registration certificate was selected as reference device A. The mean value of qualified pulse oximetry measured by pulse oximetry monitor/desktop ECG monitor was used as control group A measurement. Wearable device oximetry accuracy Arms (root mean square value of the SwO2-RefSpO2 difference) using a medical device registration certificate pulse oximetry monitor/tabletop ECG monitor as a reference. |

Secondary | Wearable device blood oxygen saturation accuracy Arms | Record the pulse oximetry and pulse rate values measured by the Huami Smart Wearable Pulse Oximetry Device. After an interval of 30 seconds, repeat the above steps to start the second measurement and record the measured value. After an interval of 30 seconds, repeat the above steps to start the third measurement and record the measured value. The average of three measurements was taken as data for the test group.A carbon monoxide blood gas analyzer (CO-oximeter) was selected as reference device B. Arterial blood was sampled and arterial oxygen saturation (SaO2) was obtained from the blood gas analyzer as a control group B measurement.Wearable device blood oxygen saturation accuracy Arms (expressed as root mean square value of the SwO2-SaO2 difference) using a carbon monoxide - blood gas analyzer (CO-oximeter) as reference. | 30mins | |
