Acumen IQ sensor produced by Edwards Lifesciences company, which is used together with the HemoSphere monitor. This intelligent sensor uses artificial intelligence to predict hemodynamic instability and optimize blood pressure and flow. The sensor is connected to the arterial line and automatically calculates key parameters every 20 seconds.

The advanced hemodynamic parameters measured by this sensor are as follows:

• Pressure changes over time (dP/dt)
• Arterial dynamic elasticity (Eadyn)
• Stroke volume (SV)
• Stroke volume variation (SVV)
• Mean arterial pressure (MAP)
• Cardiac index (CI)
• Systemic vascular resistance (SVR)
• Blood Pressure Predictive Index (HPI)
