Surveillance hémodynamique non invasive.
Designation:
Non-invasive hemodynamic monitoring system for the continuous measurement of blood pressure and advanced cardiovascular parameters.
Manufacturer: Finapres Medical Systems (The Netherlands).
Main Function:
- Continuous, beat-to-beat measurement of systolic, diastolic, and mean arterial blood pressure.
- Advanced evaluation of cardiac output (CO), total peripheral vascular resistance (TPR), stroke volume (SV), and heart rate variability (HRV).
- Real-time, completely non-invasive cardiovascular monitoring intended for clinical settings and human physiology research.
Technical Characteristics:
Method: Volume Clamp methodology utilizing a highly sensitive Finger Cuff (photoplethysmography).
Measurement Range: Arterial Blood Pressure: 0–250 mmHg.
Sampling Frequency: High fidelity data acquisition up to 200 Hz.
Connectivity: Interfaces via USB, Bluetooth, and/or Ethernet depending on the hardware configuration.
Included Software: NOVA Software for seamless data acquisition, real-time waveform analysis, and broad export capabilities.
Weight: ~3 kg (making it portable for both laboratory experiments and field research).
Options/Expansions: Supports modular add-ons for integrating 3-lead ECG, SpO₂, and calibrated cardiac output sensors.
Usage:
- Continuous hemodynamic tracking in clinical and applied physiological research.
- Evaluation of beat-to-beat cardiovascular autonomic responses to exercise, orthostatic challenges (e.g., tilt-table tests), or pharmacological stimuli.
- Detailed studies on blood pressure variability, baroreflex sensitivity, and cardiac output dynamics.
- Sports science applications for real-time, non-invasive physiological monitoring during stress tests.
Advantages:
- Provides continuous, highly precise, and reliable blood pressure curves entirely non-invasively.
- Excellent portability, bridging the gap between rigorous laboratory setups and field environments.
- Real-time hemodynamic waveform analysis supported by dedicated, advanced software.
- Allows dynamic tracking of complex cardiovascular parameters that usually require invasive arterial lines.
Limitations:
- High acquisition cost for the complete system.
- Highly sensitive to movement artifacts, ambient temperature, or improper positioning of the finger cuff.
- Requires a specific learning curve and training for optimal setup and reliable data interpretation.
