Question

My Sleep score or quality in Samsung Health's Sleep was Good. How did the watch detect signs of sleep apnea?

Answer 1

If user's Samsung Health version is confirmed to be v6.28 or lower from the log data or question

Samsung Health's Sleep score or quality does not use blood oxygen measurements (sleep stage information is used), but Samsung Health Monitor's Sleep apnea feature tracks how many relative decreases in blood oxygen you have during sleep to detect signs of sleep apnea. Therefore, the measurement results from the two apps are not related to each other. Please refer to the information provided within Samsung Health Monitor app based on the detection result of sleep apnea risk, and talk to your doctor first  if the watch has detected signs of sleep apnea.

Answer 2

If user's Samsung Health version can't be confirmed, or confirmed to be v6.29 or higher from the log data or question

The measurement results from the two apps are affected by blood oxgen saturation levels, but in different ways in each app. Samsung Health's Blood oxygen saturation reflected in Sleep score is the ratio of oxygen saturation values below 90% compared to total sleep. Blood oxygen saturation information used for the Sleep apnea feature is frequency of relative decreases in blood oxygen level. Therefore, the measurement results from the two apps are not related to each other. Please refer to the information provided within Samsung Health Monitor app based on the detection result of sleep apnea risk, and talk to your doctor first  if the watch has detected signs of sleep apnea.
