An SpO₂ sensor is part of a pulse oximeter system, used to measure the oxygen saturation of your blood non-invasively. It works by shining two light wavelengths (red and infrared) through your skin (usually a fingertip or earlobe). The sensor detects how much light is absorbed by oxygenated vs. deoxygenated haemoglobin to estimate the percentage of blood that is carrying oxygen.
Philips SpO₂ sensors use a pair of LEDs (red + infrared) and a photodetector to measure how much light passes through the capillary beds (usually a finger, toe, or alternate site). The monitor calculates oxygen saturation (SpO₂) and pulse rate from these signals — critical for monitoring patients in ICU, OR, or transport settings.
-
Compatibility matters: SpO₂ sensors are not universal — you must match the sensor type and connector to the specific monitor brand/model (e.g., Philips FAST, Masimo algorithm, or Nellcor Oximax), as connectors and signal processing standards differ between manufacturers.
-
Reusable vs. Disposable:
-
Reusable sensors (like many Philips and Nellcor probes above) are intended for multiple patients and can be cleaned/ disinfected according to hospital protocols.
-
Disposable sensors are single-patient use and help prevent cross-contamination (not shown above but available depending on brand and monitor type).
-
-
Age/size matter: Choose adult, paediatric, or neonatal versions depending on patient size — adult finger clips aren’t suitable for neonates, and vice versa.
-
Patient Monitor Compatibility: Philips SpO₂ sensors (like the M1191T, M1192T, M1193T series) are part of a T-Series portfolio designed for use with Philips patient monitors (IntelliVue, SureSigns, Fast-series, etc.) and many OEM monitors. These sensors plug into the monitor or SpO₂ measurement module and provide continuous arterial oxygen saturation and pulse rate.
-
Connector & Technology: Different monitors use specific connectors (8-pin, 9-pin, or 12-pin) and sometimes different SpO₂ algorithms (e.g., Masimo vs Philips FAST). Be sure to match the sensor’s connector and technology to your specific monitor model.
