[2025-10-01T15:47:54.463098] [PI reasoning] **Considering sensor sterilization**

I see that result 1 mentions sensors aren’t sterilizable, and the manufacturer suggests using plastic barrier sheaths to avoid contamination. So, I’m leaning toward option D. The reasoning I’ll include is that these sensors can't be heat sterilized, so they need a single-use, impervious plastic barrier for protection against cross-infection. If that barrier is compromised, they should be disinfected after use. That's it!
