The OXY-55 pulse oximeter is a non-invasive handheld device designed for spot-check or continuous monitoring of blood oxygen saturation (SpO2) and heart rate (PR) in adult, pediatric, and neonatal patients, both at home and in hospital. It uses advanced oxyhemoglobin photoelectric inspection technology combined with capacity pulse scanning and recording. The device displays SpO2, heart rate, bar graph, pulse waveform, and perfusion index (IP) values.
