心血管疾病如心衰也可导致血氧饱和度下降。 2.脉率:血氧仪上以PR表示,单位是:次/分,用于监测脉搏,它的正常值往往是在60-100之间。在紧张或运动时脉率会增快,静息时减缓。特殊体质如运动员静息脉率也可小于60次/分,属于正常生理现象。在各种心律失常时可出现脉率的异常,如心房颤动、房室传导阻滞。
1)指脉氧仪夹在手指上(可选用食指、中指、无名指),显示屏朝上,确保手指无抖动;(注:部分“指脉氧夹”没有夹上手指后自动开机功能,需要按一下设备上的按键开机)便携式指脉氧仪无按键款便携式指脉氧仪按键款 2)等待5秒左右,屏幕显示检测结果:其中%SpO2为血氧指标、PRbpm为脉搏。 3.“指脉氧”正常应为多少...
这个是血氧饱和度 正常的话是100的，目前是轻度的缺氧的了。
你的这种情况需要去医院检查确诊，平时要注意饮食调理，不要吃辛辣刺激性食物，油腻食物，要吃柔软易于...
