Adaptive Rate Limiting for Medical Device Telemetry API

Create a dynamic rate limiting strategy for a medical device telemetry API that automatically adjusts request thresholds based on device criticality, patient risk level, and real-time network conditions. The system must prioritize emergency medical devices, implement exponential backoff for non-critical devices, and provide comprehensive logging for compliance auditing. Include mechanism for handling sudden data surge during medical emergencies without disrupting critical patient monitoring streams.
