Hard real-time deterministic scheduling algorithms preventing priority inversion in ventilators and monitors.
When lower-priority logging tasks lock shared buses needed by high-priority heart rate algorithms, fatal latency spikes occur. Priority Inheritance Protocols (PIP) dynamically elevate thread priority to unblock critical resources.
Interrupt service routines (ISRs) are strictly bounded to microsecond durations, offloading computational tasks to deterministic worker queues to ensure high-frequency ADC sampling is never missed.
