What is an Anesthesia Record?

• An Anesthesia Record is a detailed account of
  the procedures performed and the anesthesia
  administered during the peri-operative period.
  The recorded information includes
• Vital Signs
• Surgical Interventions (i.e. Tourniquets)
• Anesthetics Administered (Types and Amounts)

3
Why are Anesthesia Records Necessary?

• To Smooth the Transition from the Operating Room
  to the Recovery Room
• Guide for Future Procedures
• Legal Documentation of Events

4
The Earliest System Hand-kept Records

• These were a problem because they were
• Subjective
• Often Illegible
• Distracting to the Anesthesiologist During the
  Procedure, Especially During Crises

5
Early Automated Systems General Instrumentation

• Central Processing Unit
• A/D Converter
• Serial Board
• Keypad

6
Automated Systems General Functions

• Touch-Screen/Keypad User Interface
• Alarms
• Read Out, Recorded Blood Gasses
• Plotted Vital Statistics-- Heart Rate, Blood
  Pressure, Etc.
• Record of Procedures and Times when Each Occurred
• Record of Who Performed the Procedure
• Billing Information
• Anesthesia Totals Types Ordered and Amounts
  Delivered

7
Criteria for Judging a System

• Board Approval (FDA)
• System Outputs/User Inputs
• Cost
• Compatibility with Existing Instrumentation
• Training Involved in Implementing the System/User
  Interface
• Software Modification and Updates
• Additional Features

Saturn Information System
11
Saturn Information System

• 32-bit for use with Windows NT
• User friendly
• Highly adaptable
• Security to prevent unauthorized access
• Timed movements of records from local level to
  servers
• Very expensive

12
Anesthesia Component Monitoring System
13
ACMS

• Component Modularity
• Data Transfer Module transferring patients
  vital signs and demographic info
• Recorder Module patient data documentation
• Vue Link Module interfacing to external devices
• Advanced alarm system of sounds and colors

14
Conclusions

• We recommend the ACMS because of its high
  modularity, easy integration into current
  environment, plenty of adaptations

15
Forecasts

• Units will become readily accessible from remote
  locations (ie. The home)
• The open architecture allows the system to be
  extended well into the future
• Will become more compact and mobile
• More customization to the individual or the
  doctor
