背景技术Background Art
睡眠呼吸暂停对健康危害大，全球近10亿人有睡眠呼吸暂停问题，如果呼吸暂停时间过久，会导致血氧降低，低血氧会损伤心、脑等器官，影响身体健康。睡眠呼吸暂停引发的过低血氧可能会激发恶性心血管事件，比如常见的夜间心肌梗死死亡。然而，睡眠呼吸暂停综合征患病知晓率不到20％，临床上需要在多组设备的监测下进行筛查，不适用于家庭日常。Sleep apnea is a serious health hazard. Nearly 1 billion people worldwide have sleep apnea. If apnea lasts too long, it will cause low blood oxygen, which can damage the heart, brain and other organs and affect physical health. Low blood oxygen caused by sleep apnea may trigger malignant cardiovascular events, such as common nocturnal myocardial infarction and death. However, the awareness rate of sleep apnea syndrome is less than 20%, and clinical screening requires monitoring under multiple sets of equipment, which is not suitable for daily home use.

T is the sleep reference heart rate, which can be the average heart rate of the user in the sleep state, reflecting the user's basic heart rate level during sleep; Δa is the range of change of the user's heart rate in the sleep state based on the average heart rate.
在另一些实施例中，第二电子设备可以通过加速度传感器、陀螺仪等运动传感器获取用户的运动参数，进而，可以基于该运动参数分析用户的运动情况，在用户处于静止时，则确定用户处于睡眠状态。In other embodiments, the second electronic device may obtain the user's motion parameters through motion sensors such as acceleration sensors and gyroscopes, and then analyze the user's motion conditions based on the motion parameters, and when the user is stationary, determine that the user is in a sleeping state.
可以理解，第二电子设备还可以结合心率传感器和运动传感器获得的数据融合检测用户的睡眠状态，此时，在采集到的心率处于第一心率范围且用户处于静止时，才确定用户处于睡眠状态。It is understandable that the second electronic device can also combine the data obtained by the heart rate sensor and the motion sensor to detect the user's sleeping state. At this time, it is determined that the user is in a sleeping state only when the collected heart rate is within the first heart rate range and the user is stationary.
S204、第二电子设备检测用户是否发生睡眠呼吸暂停。S204: The second electronic device detects whether the user has sleep apnea.
第二电子设备包括如图2B中所示的血氧传感器，通过血氧传感器采集用户的血氧饱和度，具体可以参见上述图2B的相关描述，此处不再赘述。第二电子设备在检测到用户处于睡眠状态且血氧饱和度小于第一血氧阈值时，确定用户发生睡眠呼吸暂停，进一步地，可以执行步骤S206。反之，第二电子设备在检测到所述用户处于睡眠状态，但血氧饱和度不小于第一血氧阈值时，确定用户未发生睡眠呼吸暂停，则返回执行步骤S202。The second electronic device includes a blood oxygen sensor as shown in FIG2B , and the blood oxygen saturation of the user is collected through the blood oxygen sensor. For details, please refer to the relevant description of FIG2B above, which will not be repeated here.

The total power is the sum of the powers of the first ultrasonic wave reflected by all points of the upper body of the user.
第一电子设备在用户反射的第一超声波的总功率小于目标阈值时，确定用户的睡姿为仰卧，进一步地，可以执行下述步骤S216。反之，第一电子设备在用户反射的所述第一超声波的总功率不小于目标阈值时，确定用户的睡姿不为仰卧，则可执行步骤S215。When the total power of the first ultrasonic wave reflected by the user is less than the target threshold, the first electronic device determines that the user's sleeping posture is supine, and further, the following step S216 can be executed. Conversely, when the total power of the first ultrasonic wave reflected by the user is not less than the target threshold, the first electronic device determines that the user's sleeping posture is not supine, and step S215 can be executed.
其中，第一电子设备可以根据用户的身高和用户与第一电子设备的距离，确定上述目标阈值。在上述距离不变时，身高越大，目标阈值越大；在上述身高不变时，距离越大，目标阈值越小。The first electronic device may determine the target threshold according to the height of the user and the distance between the user and the first electronic device. When the distance remains unchanged, the target threshold increases with the height; when the height remains unchanged, the target threshold decreases with the distance.

When the acquired heart rate is within the first heart rate range, the first electronic device determines that the user is in a sleeping state, and further, step S304 can be executed. On the contrary, when the acquired heart rate is not within the first heart rate range, the first electronic device can return to execute step S302.
其中，第一心率范围是以所述用户的睡眠基准心率为中心的心率范围，可以表示为“T±Δa”。其中，T为睡眠基准心率，睡眠基准心率可以是用户在睡眠状态下的平均心率，反映了用户在睡眠期间的基础心率水平；Δa为用户在睡眠状态下心率基于平均心率的变化幅度。The first heart rate range is a heart rate range centered on the user's sleep reference heart rate, which can be expressed as "T±Δa". T is the sleep reference heart rate, which can be the average heart rate of the user in the sleep state, reflecting the user's basic heart rate level during sleep; Δa is the range of change of the user's heart rate in the sleep state based on the average heart rate.
S304、第一电子设备检测用户是否发生呼吸暂停。S304: The first electronic device detects whether the user has respiratory arrest.
第一电子设备接收第二电子设备发送的生理信息，该生理信息包括用户的血氧饱和度。第一电子设备在检测到用户处于睡眠状态且所述血氧饱和度小于第一血氧阈值时，确定用户发生睡眠呼吸暂停，进一步地，可以执行步骤S306。反之，第一电子设备在检测到所述用户处于睡眠状态，但血氧饱和度不小于第一血氧阈值时，确定用户未发生睡眠呼吸暂停，则返回执行步骤S302。The first electronic device receives physiological information sent by the second electronic device, and the physiological information includes the blood oxygen saturation of the user. When the first electronic device detects that the user is in a sleeping state and the blood oxygen saturation is less than the first blood oxygen threshold, it determines that the user has sleep apnea, and further, step S306 can be executed. On the contrary, when the first electronic device detects that the user is in a sleeping state, but the blood oxygen saturation is not less than the first blood oxygen threshold, it determines that the user does not have sleep apnea, and returns to execute step S302.

在另一些实施例中，第二电子设备还可以通过运动传感器采集用户的运动参数，并将运动参数发送至第一电子设备。第二电子设备可以基于生理信息、运动参数和第一声音等综合判断用户是否处于睡眠状态，是否发生呼吸暂停。具体的，第一电子设备在基于运动参数识别用户处于静止、血氧饱和度低于第一血氧阈值、且第一声音检测不到呼吸声时，确定用户处于睡眠状态，且发生呼吸暂停；反之，第一电子设备在基于运动参数识别用户处于静止，血氧饱和度不低于第一血氧阈值、且第一声音检测到呼吸声时，确定用户处于睡眠状态，但未发生呼吸暂停。或者，第一电子设备在基于运动参数识别用户处于静止，且血氧饱和度低于第一血氧阈值或第一声音检测不到呼吸声时，确定用户在睡眠状态下发生呼吸暂停；反之，第一电子设备在基于运动参数识别用户处于静止，但血氧饱和度不低于第一血氧阈值且第一声音检测到呼吸声时，确定用户在睡眠状态下未发生呼吸暂停。可以理解的，第一电子设备在基于运动参数识别用户未处于静止，则可以确定用户未处于睡眠状态。In other embodiments, the second electronic device may also collect the user's motion parameters through a motion sensor and send the motion parameters to the first electronic device. The second electronic device may comprehensively judge whether the user is in a sleeping state and whether apnea occurs based on physiological information, motion parameters, and the first sound. Specifically, when the first electronic device identifies that the user is stationary based on the motion parameters, the blood oxygen saturation is lower than the first blood oxygen threshold, and the first sound cannot detect the breathing sound, it determines that the user is in a sleeping state and apnea occurs; conversely, when the first electronic device identifies that the user is stationary based on the motion parameters, the blood oxygen saturation is not lower than the first blood oxygen threshold, and the first sound detects the breathing sound, it determines that the user is in a sleeping state, but apnea does not occur. Alternatively, when the first electronic device identifies that the user is stationary based on the motion parameters, and the blood oxygen saturation is lower than the first blood oxygen threshold or the first sound cannot detect the breathing sound, it determines that the user has apnea in the sleeping state; conversely, when the first electronic device identifies that the user is stationary based on the motion parameters, but the blood oxygen saturation is not lower than the first blood oxygen threshold and the first sound detects the breathing sound, it determines that the user has not apnea in the sleeping state. It can be understood that when the first electronic device recognizes that the user is not stationary based on the motion parameters, it can determine that the user is not in a sleeping state.

On the contrary, when the total power of the first ultrasonic wave reflected by the user is not less than the target threshold, it is determined that the user's sleeping posture is not supine, and the first electronic device can return to step 302 to detect whether the user is in a sleeping state.
其中，第一电子设备可以根据用户的身高和用户与第一电子设备的距离，确定上述目标阈值。在上述距离不变时，身高越大，目标阈值越大；在上述身高不变时，距离越大，目标阈值越小。The first electronic device may determine the target threshold according to the height of the user and the distance between the user and the first electronic device.
