Find an SpO2 sensor compatible with your monitor

In short: Which SpO₂-Sensor fits, decides the Connection to the monitor, Not the device name. First check the socket and the number of pins, then the patient group. Many systems use an adapter cable between the sensor and the monitor, which determines the sensor type.

Connection systems by manufacturer#

Each manufacturer uses its own connectors. Therefore, the same sensor design is not automatically compatible with a different device. The following overview matches the common systems to the monitors for which we stock sensors.

Why the adapter cable makes all the difference#

In most systems, the sensor isn't directly integrated into the monitor. An adapter cable connects them, translating the sensor's functionality to the monitor's. This has two implications: A home with a mix of devices can manage with just a few sensor types, provided the appropriate adapter cables are available. And if a sensor doesn't work on a neighboring monitor, the problem is often not with the sensor itself, but with the wrong cable.

• An adapter cable to GE Datex measures 2.4 m and serves, among others, Dash 2000, Solar 8000 and the Tram modules 451, 451N and 851.
• Nellcor sensors are available with and without OxiMax technology. The version must be compatible with the device; the connector type alone is not sufficient.

Patient group and sensor size#

Sensors are categorized according to body weight and measurement location. The abbreviations follow the same pattern for most manufacturers.

Y-sensors eliminate the need for different sizes: they can be placed on fingers, toes, or hands, thus covering multiple sizes. Ear sensors are an alternative if blood flow in the hand makes measurement difficult.

Find the right sensor in four steps#

• Look at the socket. The number of poles and the shape on the monitor determine the system, not the device name on the casing.
• Check the adapter cable. If one is present, the sensor aligns itself with its sensor side.
• Select patient group. Weight and measuring point determine design and size.
• Specify whether it's single-use or reusable. Adhesive sensors are intended for single use, finger clips and silicone pouches for reuse.

Frequently Asked Questions#

How can I tell which SpO2 sensor is compatible with my monitor?

The connector is located on the device itself, not on the device name. Count the pins and compare the shape: Philips and HP use an 8-pin D-connector, Nihon Kohden a 14-pin, Nonin a 7-pin, and Nellcor the 9-pin DB9. If an adapter cable is used, the sensor will align itself according to the sensor side of the adapter.

Can I use a sensor from a different manufacturer?

Only if the connection and signal processing match. Compatible sensors are available for many systems; they are marked as such in our product range. A mechanically compatible connector alone is not enough: Nellcor also distinguishes between versions with and without OxiMax.

What distinguishes disposable from reusable sensors?

Disposable sensors are adhesive sensors for one patient and are supplied in packs of 20 or 25. Reusable sensors such as finger clips, silicone pouches, and ear clips are designed for repeated use and are reprocessed between patients.

What do I need an SpO2 adapter cable for?

It connects the sensor and monitor and determines which sensor type is compatible. The standard length is between 2.4 m and 3.0 m. With a mixed set of devices, it's worthwhile to standardize using adapter cables: then a few sensor types are sufficient for many monitors.

Which sensor size is appropriate for which patient?

The sizing is based on body weight: NeoPT for premature infants, Neo for newborns under 3 kg, Inf for infants, Pdt for children, Adt for adults from about 40 kg. Y-sensors cover several sizes because they are attached to the finger, toe or hand.

Do you also carry sensors for older monitors?

Yes. Our product range extends from current systems to devices such as Philips Viridia, Datex Cardiocap, and the early BSM series from Nihon Kohden. Please tell us the device type and year of manufacture, and we will check the compatibility.
