Need to buy batteries by yourself Blood oxygen saturation measurement range: 70%-99% Blood oxygen saturation measurement accuracy: within the range of 70%-99%±2%, ≤70% is undefined Blood oxygen saturation resolution: blood oxygen saturation ±1%, Pulse rate measurement range: 30BPM-250BPM Pulse rate measurement accuracy: ±1BPM or measurement value ±1% (whichever is greater) Blood perfusion index measurement range: 0.2%-30% Blood perfusion index PI: ≥0.2%, ±0.1% Power consumption: less than 30MA. Automatic shutdown: when no finger is inserted, it will automatically shut down after 8 seconds Storage humidity: 15%-80% when working, 10%-80% when storing Battery model: 2*1.5V (2 AAA alkaline, the product does not contain batteries) Working temperature: 5℃-4℃ Atmospheric pressure: 70Kpa-106kpa Material: ABS+PC Product size: 60*30*30mm Product net weight: 36g Monitoring parameters SpO2: Oxyhemoglobin photometer (SpO2) Patient type: suitable for all people over 4 years old Measuring range: 70-99% Analysis: 1% Accuracy: 70%--99%±2% Insufficient oximeter: an important indicator of offline situations. Under normal circumstances, the blood oxygen saturation value should not reach 94%. If the oxygen saturation is lower than 94%, the oxygen supply is considered insufficient. Heart rate pulse repetition frequency (PR) BPM: Measuring range: 30 bpm-250 bpm bpm solution: 1 Accuracy: 1% or 1 bpm Heart Rate (Heart Rate): refers to the number of times the heart beats per minute. It means how fast the heart beats within a certain period of time. The same person, the heart rate slows down during quiet or sleep, and increases during exercise or when emotionally excited! Perfusion indicator PI value: Measuring range 0.2%-30% PI Resolution: 1% PI refers to the Perfusion Index (PI), and the PI value reflects the pulsating blood flow, that is, reflects the blood perfusion ability. The greater the pulsating blood flow, the greater the pulsating component and the greater the PI value. Therefore, the measurement site (skin, nails, bones, etc.) and the patient's own blood perfusion (arterial blood flow) will affect the PI value. Since sympathetic nerves affect heart rate and arterial blood pressure (influencing pulse arterial blood flow), the human body's neuromodulation system or mental state will also indirectly affect the PI value. Therefore, under different anesthesia states, the PI value will be different. #oximeter #ChildPulseOximeter #Baby #oximetry
