Key Features and Benefits of This Multi-Y Pulse Oximetry Sensor
- One sensor for all patient sizes: The Y-type emitter/detector head attaches to different sites with a wrap or adhesive strip, so a single sensor covers adult, pediatric, infant and neonatal monitoring.
- Masimo RD SET signal technology: Built to work with monitors and patient cables that accept Masimo RD SET sensors for SpO2 and pulse rate readings.
- Reusable design: Cleaned and reused between patients, lowering cost per use compared with single-use adhesive sensors.
- Practical 1.0 m cable: A short bedside length that reduces cable clutter and connects to an RD SET patient/extension cable.
- Complete set: Supplied as 1 set per bag with the Y-sensor, a foam wrap holder and adhesive attachment strips (as pictured).
- Certified quality:
