The BPL Smart Oxy Finger Pulse Oximeter is a portable medical device used to measure a person's blood oxygen saturation level (\(SpO_{2}\)), pulse rate, and Perfusion Index (PI). It is designed for both home and clinical use, featuring a color OLED display, audible and visual alarms for abnormal readings, and enhanced accuracy during motion. This oximeter is ideal for patients with respiratory or heart conditions like Asthma, COPD, or heart failure, as well as for monitoring fitness levels or post-operative oxygen saturation.
