SpO2 sensor cables are not universally interchangeable. The correct replacement depends on the patient monitor brand and model, SpO2 technology, connector design, pin layout, patient type and reference number.
Are all SpO2 sensor cables compatible?
No. Sensors that look similar can use different electronics, connector keying and pin assignments. Always match the monitor model and existing sensor reference before ordering.
How do I know which SpO2 sensor I need?
Check the patient monitor brand and exact model, the sensor part number, connector shape and pin count, and whether the monitor uses a specific technology platform such as Nellcor or Masimo.
What is the difference between reusable and disposable SpO2 sensors?
Reusable sensors are designed for repeated use when handled and cleaned according to the manufacturer instructions. Disposable sensors are generally intended for single-patient or short-term use depending on the product and clinical setting.
Do adult and paediatric SpO2 sensors use the same cable?
Not always. Patient application, probe design and cable assembly can differ between adult, paediatric, infant and neonatal sensors.
Can I choose an SpO2 sensor only by connector shape?
No. Connector shape alone is not enough. Two sensors can appear physically similar but use different pin configurations or signal technology.
Where can I find replacement SpO2 sensors in Australia?
Medical Equipments Australia lists a broad range of reusable replacement options. Browse the Reusable SpO2 Sensors category. For brand compatibility guidance, see the SpO2 Sensor Compatibility Guide, the Philips, Nellcor, Masimo, Mindray and GE SpO2 Replacement Buying Guide, and the SpO2 Connector and Cable Guide.
