JianyouCare Fingertip Pulse Oximeter Portable OLED Blood Oxygen Monitor

The JianyouCare fingertip pulse oximeter is a modern portable medical device designed for quick and accurate measurement of blood oxygen saturation, heart rate, and respiratory rate. This compact oximeter uses advanced OLED screen technology, providing clear display information in four directions. The fingertip pulse oximeter is ideal for individuals who want to monitor their heart health at home, in the hospital, or while traveling.

Main features of the fingertip pulse oximeter

• Oxygen saturation (SpO2) — measures blood oxygen saturation from 70 to 99 percent with 2 percent accuracy. If readings are below 94 percent, it indicates insufficient oxygen levels in the body.
• Heart rate (PR) — determines pulse from 30 to 250 beats per minute, providing real-time heart activity data at any time.
• Perfusion index (PI) — measures blood circulation quality from 0.2 to 30 percent, showing blood supply to finger tissues.
• Respiratory Rate (RR) — detects the respiratory rate, which is 16–20 breaths per minute for adults, 20–30 for children, and up to 44 for newborns.
• OLED display — the blue and yellow dual-color display ensures clear vision from any angle and easy-to-read information.
• Four display modes — flexible display directions allow viewing data from four different positions, improving ease of use.
• Energy saving — two AAA batteries last for more than 40 hours, and the automatic shutdown after 8 seconds without a signal further enhances economy.
