Background
• A use of medicine to prevent the feeling of pain or another sensation during the operation
• Few fatal errors occur during Anaesthesia administration
• 80% are preventable human mistakes
• Needs of Computerised Diagnosis

How it works
![Page 4: A Multi-modal Alert System for Anaesthesia Diagnosis Part IV Project – Software Engineering](https://reader035.vdocuments.us/reader035/viewer/2022081604/5681649c550346895dd6805a/html5/thumbnails/4.jpg)
Current Issues
• Increasing number of monitors in operating room
• Low identification rate / High false alarm rate
• Discrepancies between clinical and perceived urgencies
• Ineffective Display

Gathering User Requirements
• Research previous works
• One-to-One interviews with Anaesthesiologists
• Field Trips
• Consultation with an area expert

Development Tool
• Required to use LabVIEW 8.5
• Graphical programming for measurement and automation
• For easy transition of project
![Page 12: A Multi-modal Alert System for Anaesthesia Diagnosis Part IV Project – Software Engineering](https://reader035.vdocuments.us/reader035/viewer/2022081604/5681649c550346895dd6805a/html5/thumbnails/12.jpg)
Key Implementations
• Visualising low fidelity prototypes
• Text-to-Speech in LabVIEW 8.5
• Plotting graph with real-time (time series)

Conclusions
• Clear and Easy Multi-Modal alarms
• High Identification Rate without further learning progress
• No interference to others (surgeons / patients)
• Improved user control setting
