The Fitbit Versa 4 does not have a dedicated feature to detect sleep apnea like the Samsung Galaxy Watch 7. Fitbit devices, including the Versa series, can track sleep patterns and vital signs, but they are not designed to diagnose sleep apnea directly. They use sensors like accelerometers and photoplethysmography (PPG) to monitor movement and heart rate, which can indirectly suggest potential sleep disturbances, but these are not specific indicators of sleep apnea[1][3][4].
On the other hand, the Samsung Galaxy Watch 7 includes a sleep apnea detection feature that uses its blood oxygen sensor to monitor oxygen levels during sleep. This feature is designed to identify potential cases of moderate to severe obstructive sleep apnea and is cleared by the US Food and Drug Administration (FDA). It requires wearing the watch for at least two nights over a 10-day period to function effectively. While it does not provide a definitive diagnosis, it can alert users to consult a healthcare professional for further evaluation[2][5][8].
Fitbit devices, including the Versa series, can provide insights into sleep quality and patterns, which might indirectly suggest the need for a sleep apnea test if other symptoms are present. However, they do not offer a specific sleep apnea detection feature like the Samsung Galaxy Watch 7[3][4]. If you suspect sleep apnea based on symptoms such as frequent snoring, daytime fatigue, or other related issues, it is advisable to consult a healthcare professional for a proper diagnosis and treatment plan[9].
