Key Monitoring Parameters in Anesthesia
An ideal anesthetic monitor should accurately and continuously track the following vital signs:
Electrocardiogram (ECG)
Non-invasive and invasive blood pressure (NIBP/IBP)
Oxygen saturation (SpO2)
End-tidal CO₂ (EtCO₂)
Respiratory rate
Temperature
Anesthetic agent concentration
Neuromuscular function (TOF monitoring)
Depth of anesthesia (e.g., BIS or entropy)
Evaluation Criteria for Anesthetic Monitors
1. Accuracy and Reliability
Devices must provide consistent, real-time data under dynamic surgical conditions.
Monitors should be validated by clinical trials and meet international standards (e.g., CE, FDA).
2. User Interface and Usability
Touchscreen displays, customizable dashboards, and intuitive menu structures enhance workflow.
Adjustable alarm thresholds and ergonomic design reduce distraction and improve focus during procedures.
3. Modular vs. All-in-One Systems
Modular Systems: Allow component customization and scalability.
All-in-One Systems: Provide compact integration but may be less flexible for advanced cases.
4. Integration and Data Export
Compatibility with anesthesia information management systems (AIMS) and EHRs for automatic data documentation.
Wireless connectivity or USB data export features for post-op review and analytics.
5. Portability and Versatility
Some settings require lightweight, battery-powered units for mobility in satellite ORs or during patient transfers.
Cost Considerations
Monitor Type Estimated Cost Range (USD)
Basic Multiparameter Monitors $3,000 – $8,000
Advanced Anesthesia Monitors (BIS, EtCO₂) $10,000 – $25,000
High-End Integrated Workstations $30,000 – $60,000+
Note: Maintenance contracts, software licenses, and training may incur additional costs.
