The Masimo LNCS infant SpO2 sensor is a reusable soft tip pulse oximetry probe built to the Masimo 2258 LNCS Y-I reference specifications. It has a 1.0m (3.3 ft) cable and a soft silicone tip sized for infant fingers and toes. It gives continuous oxygen saturation (SpO2) and pulse rate readings on monitors that use Masimo LNCS technology.
Key Benefits of This Infant Soft Tip SpO2 Sensor
- Gentle on small patients: The soft silicone tip wraps closely around an infant digit, so it stays in place without pressing hard on delicate skin.
- Less signal loss from light and motion: The enclosed tip keeps out ambient light, which helps readings stay steady when the infant moves.
- Lower cost per patient: One reusable sensor can be cleaned and used many times, so you buy fewer single-use adhesive sensors.
- Plugs straight in: The LNCS connector goes directly into Masimo LNCS patient cables and LNCS-equipped monitors. No adapter is needed.

Where This Reusable Infant SpO2 Sensor Is Used
- Neonatal intensive care units (NICU) and special care nurseries
- Pediatric wards and paediatric emergency departments
- Infant sedation and procedural monitoring
- Neonatal and pediatric transport with portable monitors and defibrillators
- Pediatric sleep studies and overnight oximetry
How to Apply and Care for the Sensor
Application
- Choose a well-perfused finger or toe that fits the infant soft tip.
- Slide the digit fully into the tip so the emitter and detector line up across the nail bed.
- Route the cable away from the patient and secure it loosely to reduce tugging.
- Check the site at regular intervals and move the sensor as your facility’s protocol requires.
Cleaning
- Unplug the sensor from the monitor before cleaning.
- Wipe the tip and cable with 70% isopropyl alcohol or a mild hospital-grade disinfectant.
- Let it air dry fully before the next use. Do not soak or autoclave it.
Frequently Asked Questions
What is the Masimo 2258 reference infant soft tip SpO2 sensor?
It is a reusable pulse oximetry sensor built to the Masimo 2258 LNCS Y-I reference specifications. It has a soft silicone tip sized for infants and a 1.0m cable. It measures SpO2 and pulse rate on Masimo LNCS monitors.
Is this sensor reusable?
Yes. It is a reusable sensor that you clean between patients, so it costs less over time than single-use adhesive infant sensors.
How is it different from the Masimo 2258 multi-site Y sensor?
The original Masimo 2258 is a multi-site Y-sensor that is held on with wraps. This version has a fixed soft tip made for infant fingers and toes, so it goes on quickly without extra wraps or tape.
What patient weight or size is it for?
It is sized for infants. For older children or adults, choose a pediatric or adult soft tip or hard shell sensor instead. For very small neonates, a neonatal wrap sensor is the usual choice.
Does it need an adapter cable?
No. The LNCS connector plugs straight into Masimo LNCS monitors and LNCS patient cables. You only need an adapter if your monitor uses a different Masimo connector, such as an LNOP or Rainbow port.
Is this sensor new?
Yes. Every sensor is supplied new in its sealed bag.
