- 2. Introduction Existing System Proposed System Architecture Conclusion Outline 1 Introduction 2 Existing System 3 Proposed System 4 Architecture 5 Conclusion DYNAMIC ALERT LEVEL DETERMINATION
- 3. Introduction Existing System Proposed System Architecture Conclusion Introduction In HIMS Continuous monitoring of the vital parameter is requied The instruments used are ⇒ duel parameter monitor, ⇒ multi-parameter monitor, ⇒ central monitoring stations, etc. Alerts are generated when a preconditions are voilated. DYNAMIC ALERT LEVEL DETERMINATION
- 4. Introduction Existing System Proposed System Architecture Conclusion Existing System In the existing system alerts are static ⇒ hard and soft limit Frequent voilation of precondition occurs. So these alarms are usually ignored by nurses and may cause problems. DYNAMIC ALERT LEVEL DETERMINATION
- 5. Introduction Existing System Proposed System Architecture Conclusion Alert propagation based on hierarchies of clinical staff Senior Doctors ⇑ Junior Doctors ⇑ Head Nurse ⇑ Nurses In current senario, the decision for propagation is depend on the person responsible at the lower level. DYNAMIC ALERT LEVEL DETERMINATION
- 6. Introduction Existing System Proposed System Architecture Conclusion Proposed System Instead of a static system Dynamic System is generated The alerts will be dynamically generated. The system dynamically compute the seriousness of the alarm condition on a continuous basis. The Dynamic system consider both the facts ⇒ Hierarchies of clinical staff ⇒context of the recipient DYNAMIC ALERT LEVEL DETERMINATION
- 7. Introduction Existing System Proposed System Architecture Conclusion Differ alerts are ⇒ Audio alert ⇒ Text alert The selection is based on the contex DYNAMIC ALERT LEVEL DETERMINATION

- 9. Introduction Existing System Proposed System Architecture Conclusion Architecture include Classifier Decision Support System EMR Classifier module classifies the signal into Low,Normall,High,Very High Decision Support System include Smart alarm generator Context aware rule set.

- 10. Introduction Existing System Proposed System Architecture Conclusion Smart alarm generator → controll module used to identify trends Rule set defined by medicall experts DYNAMIC ALERT LEVEL DETERMINATION
- 11. Introduction Existing System Proposed System Architecture Conclusion Example code 1 IF<Pulse rate increasing>AND <Systolic blood pressure is decreasing>AND <Serum potassium level is increasing> THEN {Alert[Pulse_Rate_Dropping].level++; Alert[Pulse_Rate_Dropping].advise+= Increase fluid amount} Example code 2 IF<Body Temperature exceeds Maximum Body Temperature>AND <Heart Rate exceeds Maximum Heart Rate threshold> THEN {Alert[Medium Alert Event and contact available Duty Doctor]} DYNAMIC ALERT LEVEL DETERMINATION

- 13. Introduction Existing System Proposed System Architecture Conclusion A conventional monitoring system generates an alarm at 17th hour for systolic blood pressure drop Dynamic alert generation system monitors the trends of others parameters like diastolic blood pressure, pulse rate and serum potassium The system will identify the systolic blood pressure drop at 11th hour. System starts increasing the alarm level corresponding to Pulse rate Dropping DYNAMIC ALERT LEVEL DETERMINATION
- 14. Introduction Existing System Proposed System Architecture Conclusion Conclusion The alarms can be classified into different categories based on the parameter being monitored Alerts generated when each one crosses a dynamically set threshold. The delivery of these alerts is based on Hierarchies of clinical staff Seriousness of the alert and contex DYNAMIC ALERT LEVEL DETERMINATION
