The AESCULON® lets us take a peek into the electrical activities of the heart through a cable connected to the the four ECG surface electrodes attached to the patient. With only a few cardiac cycles, the AESCULON® is able to analyze and calculate the average values for these hemodynamic parameters: -Stroke Volume (SV) / Stroke Index -Cardiac Output (CO) / Cardiac Index (CI) -Index of Contractility (ICON®) - a dimensionless index representing the peak aortic blood acceleration in the aorta -Thoracic Fluid Index (TFI) - a dimensionless index representing the thoracic fluids -Systolic time intervals - the Pre-Ejection Period (PEP), Left- Ventricular Ejection Time (TLVE), or flow time, and the Systolic Time Ratio (STR), i.e. the ratio of PEP and TLVE. Window to the Circulation®—what better way to describe the AESCULON® than with this?
