Unverified连续高频采样与续航直接冲突，整夜连续监测（8小时1Hz）通常耗电快，选择前确认单次充电支持至少一整夜（≥10小时）连续记录，否则半夜断电丢数据88% similarUnverified整夜监测续航需≥10小时且带震动报警的机型电池要能同时支撑，实测选标称续航≥12小时的型号，避免因低电量在后半夜自动关机丢失数据87% similarUnverified夜间监测续航需≥8-10小时连续工作，且支持无线充电或双电池轮换，避免夜间断电导致监测盲区；标称续航常在满血氧持续采样下大幅缩水，实际按标称70%估算86% similarUnverified报警可靠性与续航权衡：血氧连续监测（每秒采样）耗电快，续航多为10-16小时需每日充电；传感垫型多为外接电源或续航数月的低功耗方案。追求整夜无中断监测应选带充电底座+电量低报警的产品86% similarUnverified监测指标越全（心率+血氧+体温）传感器功耗越高，续航通常缩短至8-12小时需每日充电；只测心率血氧的可达数天，需权衡：整晚监测选双电池轮换设计的机型避免充电空窗84% similar
