PhysioFlow® Q-Link™ is an advanced, noninvasive cardiac output monitoring system that utilizes Signal Morphology-based Impedance Cardiography (SM-ICG™) for highly accurate, continuous hemodynamic measurements. It is designed for clinical and research applications, offering a cost-effective, easy-to-use, and computer-connected solution for cardiovascular assessment. Detects signal abnormalities for improved
assessment.

Clinical Applications:

✔ Cardiology & Heart Failure Management​
✔ Internal Medicine & Hypertension Monitoring​
✔ Pulmonology (COPD & Thoracic Fluid Overload Assessment)​
✔ Hemodialysis Hemodynamics Optimization​
✔ Cardiopulmonary Exercise Testing (CPET)​
✔ Clinical Research & Advanced Diagnostics

Key Parameters Measured:

✅ Cardiac Output & Stroke Volume – Measures CO, CI, SV, and SVI to assess heart function.​
✅ Preload & Afterload Indices – Includes Early Diastolic Filling Ratio (Preload Index) and Systemic
Vascular Resistance (Afterload Index).​
✅ Contractility & Workload Metrics – Provides Contractility Index and Left Cardiac Work Index (MVO₂
surrogate).​
✅ Ventricular Performance Indicators – Estimates Ventricular Ejection Time (VET), Ejection Fraction
(EF), and End-Diastolic Volume (EDV).
