Core Advantages of Wireless Patient Monitoring
1. Improved Mobility and Workflow
Eliminates cable clutter in operating rooms and ICUs.
Enables better positioning of patients and equipment.
Simplifies setup during emergencies or complex surgeries.
2. Continuous and Remote Monitoring
Real-time data transmission to central stations or mobile devices.
Ideal for use in step-down units, PACUs, and ambulatory surgical centers.
Facilitates early warning for patient deterioration.
3. Integration with Anesthesia Information Systems (AIMS)
Seamless integration allows automatic documentation.
Reduces human error in recordkeeping.
4. Enhanced Patient Experience
Minimizes physical constraints and improves patient comfort postoperatively.
Key Monitoring Parameters Enabled Wirelessly
ECG/Heart Rate
Non-invasive Blood Pressure (NIBP)
Oxygen Saturation (SpO2)
End-tidal CO2 (EtCO2)
Respiratory Rate
Temperature
Challenges and Limitations
1. Signal Interference and Latency
Susceptible to disruption in environments with heavy wireless traffic.
Requires robust hospital Wi-Fi or proprietary wireless networks.
2. Battery Life and Reliability
Frequent charging or battery swaps required for uninterrupted use.
3. Data Security and Privacy
Demands compliance with data protection regulations like HIPAA.
4. Initial Investment and Infrastructure
Higher upfront costs compared to wired systems.
May require infrastructure upgrades in older facilities.
