Hello,
We have recently started seeing error messages pop up stating "Replace Sp02 Cable" or "Replace Spo2 Sensor". After some investigating it was determined from Masimo that their new version of Sensors and Cables have an internal chip which tracks usage. After a set amount of time an error message will appear. The error message will vary depending on the model of equipment being used. The sensor/cable will stop working after 72 hours of the message appearing. The reusable sensors are good for 8,760 hours and the Patient Cables are good for 17,520 hours.

Wow. Although the math says that 8,760 hours is exactly 24 hours times 365 days, so they certify the sensor for one full year of non-stop operation, and the cable for 2 years of non-stop. Almost all of the time, the sensors and cables are run for far less on-duty time than that. But still, it's sadly interesting that they have a timer in both the sensor and cable to count the hours like that. :-( SMH.
