5.1. Measurement Accuracy Considerations

• Saturasyon oksijèn: Accuracy is ±2% for readings between 70% and 99%. For readings below 70%, accuracy is not defined.
• Batman kè Accuracy is ±1% or ±1 BPM, whichever is greater.
• Weak Perfusion: The oximeter can accurately display oxygen saturation and pulse rate even with a pulse filling degree as low as 0.6%.
• Entèferans limyè: Compared to measurements in a dark room, the deviation in oxygen saturation under natural light and illuminated conditions is less than ±1%.

6. Antretyen

6.1. Netwayaj

• Netwaye sifas oksimèt la avèk yon twal mou.ampened with medical alcohol (75% ethanol) or isopropyl alcohol.
• Do not immerse the device in water or any cleaning solution.
• Ensure the device is completely dry before reuse.

6.2. Depo

• Store the oximeter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Remove batteries if the device will not be used for an extended period to prevent battery leakage.
