Choosing the right SpO2 sensor

Sensor selection depends on three things: the monitor you're using, the patient population, and whether you need reusable or single-patient-use. Clip sensors (such as the Nonin 8000AA range) suit adult spot-checking and are quick to apply. Soft sensors (8000S series) conform to the digit and are better tolerated for continuous or overnight monitoring. Flex sensors with FlexiWraps (8000J, 8001J, 8008J) are designed for paediatric, infant and neonatal patients where a clip won't fit securely. Forehead reflectance sensors (8000R) are used where peripheral perfusion is poor and finger readings become unreliable.

Nonin WristOx2 3150 sensor compatibility

The WristOx2 3150 uses a 16-pin connector and requires WO2-specific sensors — the 8000SS-WO2 (small), 8000SM-WO2 (medium) and 8000SL-WO2 (large). Standard Nonin PureLight sensors will not connect directly to the WristOx2 without the Sensor Adapter Cable, which is stocked separately. Replacement wrist bands (3150WB) and the 3150SC PC download cable for nVISION data transfer are also available.

Reusable and disposable options

Reusable sensors offer lower cost per use in settings with reliable cleaning protocols. FlexiWrap disposable adhesive wraps allow a reusable Flex sensor to be used across multiple patients while maintaining infection control — each wrap is single-patient-use and supplied 25 to a bag. Wraps are model-specific, so the 8000JFW fits the 8000J adult sensor only, the 8001JFW the 8001J neonatal sensor, and the 8008JFW the 8008J infant sensor.
