Nonin Model 7500 Pulse Oximeter is a lightweight, portable pulse oximeter delivering accurate SpO₂ and pulse rate monitoring with Hybrid Averaging™ and PureSAT® technology, supporting reliable clinical decisions across hospital, homecare, and transport settings.
The Nonin Model 7500 Pulse Oximeter provides caregivers with accurate oximetry information¹, supporting timely and confident clinical decisions when it matters most.
Equipped with Nonin Hybrid Averaging™, the Model 7500 reduces the impact of sudden SpO₂ fluctuations caused by motion artifacts or other transient conditions, while maintaining the rapid response associated with Standard/Fast Averaging. This helps minimise nuisance alarms, improve actionability, and support patient and caregiver confidence.
Lightweight, compact, and portable, the Model 7500 is suitable for monitoring infant, pediatric, and adult patients across a wide range of clinical and homecare environments. Its durable construction supports frequent and repeated use.
Multiple indicators support reliable readings, including a colour-coded pulse strength bar graph, pulse quality indicator, and sensor fault indicator.
Built to withstand continued heavy and repeated use in clinical and homecare settings.
Operates on AC line power or an internal battery, providing up to 16 hours of operation with a 4-hour recharge.
Stores up to 70 hours of recorded data for review.
Includes patient security mode and user-defined default settings to support customised patient configurations.
A colour-coded bar graph and saturation-related audible tone provide at-a-glance assessment at each pulse.
Identifies motion or signal quality changes that may require sensor site adjustment.
Uses intelligent pulse-by-pulse filtering to deliver precise oximetry measurements.
Can operate as a standalone device or interface with other equipment.
The Model 7500 includes a selectable Hybrid Averaging option that reduces nuisance alarms related to brief desaturations caused by motion or other transient factors. This feature supports focused clinical response and may reduce unnecessary emergency visits.
The Model 7500 incorporates advanced Nonin technologies, including PureSAT® pulse oximetry for intelligent signal filtering and PureLight® sensor technology combined with a bright LED display and large screen for clear visibility.
For both clinical and at-home monitoring, dependable and easy-to-use equipment is essential. The Model 7500 delivers responsive measurements across a wide range of patient conditions, from hospital to home environments.
