摘要：
Embodiments of the disclosure provide an oximeter, including a blood oxygen collecting unit that has a first light emitting unit, a second light emitting unit, and a light receiving sensor, the first light emitting unit emitting a red light, the second light emitting unit emitting an infrared light, and the light receiving sensor receiving the red light emitted by the first light emitting unit and the infrared light emitted by the second light emitting unit and not absorbed by the human body, and converting them into an electrical signal, a storage unit that stores a first threshold value, a microprocessor that calculates a blood oxygen saturation of the human body based on the electrical signal detected by the light receiving sensor, and includes a judging unit that judges whether the blood oxygen saturation is lower than the first threshold value, and a display unit.
