Don't worry, the breathing system does not rely on the Rasberry at all.
We use an electronic board that was made on purpose by a Medical company and relies on STM32 hardware.
This board sends telemetry to the Rasberry PI and we have a Rust based interface that shows charts and some controls.
If the Raspberry fails, the Firmware still run fine, and you can still change the settings on the machine using physical buttons and a LCD screen that is directly connected to the firmware
