HAEMODYN Data Acquisition Software for Hemodynamic and Cardiovascular Experiments
For hemodynamic and cardiovascular studies. Online evaluation of a wide range of signals and parameters.
The HA-HSE HAEMODYN data acquisition and monitoring software can be adapted to virtually any experimental investigation for hemodynamic experiments. Acquisition can cover signals such as left ventricular pressure, aortic pressure, aortic flow, atrial pressure, atrial flow, coronary flow, pO2, pCO2, pH, temperature, etc. Various parameters can be derived from these signals, e.g. systolic, diastolic, mean and rate (frequency) values for pressures, +/-dp/dt, +/-dLVP/dt contractility index CI, minimal, maximal, and mean flows, etc. User defined parameters can be created by formulas. ECG or other signals like temperature, pH, pO2 etc, can also be recorded.
All acquired signals and all calculated parameters can be displayed in two graphic windows (Detail and Trend) according to the settings of the user. Complete raw data of experiment are stored on hard disk and can be replayed any time later after experiment. Includes graphic selection of trend data points for easy data reduction.
HAEMODYN software is available in a basic version which includes the minimal necessary algorithms. Optional software modules are available to upgrade to a more complex system that includes all the available algorithms. The configuration of the system is defined in configuration and can be set by the user in the menu. The user only needs to calibrate the signals and fix the graphics scaling. All the hardware definitions and algorithms can be defined by the user. The configuration files can be changed according to the needs and used in combination with a set of different configuration files to match the different experiments.
HAEMODYN software can acquire a maximum of 8 or 16 channels (depending on hardware used 73-3330 (16 ch), 73-4817 (8 ch), 73-4818 (16 ch) or 73-0161 (16 ch), i.e. up to 16 different raw signals can be handled.
- Choose available signals to acquire and display.
- Choose from possible parameters to evaluate and display.
- Enter experimental protocol.
- Calibrate. (Calibration can be taken from previous experiment).
- Start data acquisition.
- Data reduction and evaluation.
During data acqusition, all acquired signals and derived parameaters are displayed on screen. All raw data and trend data are stored. Data reduction tools are included. Export of data to any statistc package are possible.

Commonly used signals on haemodynamic experiments are:
|LVP||Left Ventricular Pressure|
|pO2||Oxygen Partial Pressure|
|pCO2||Carbon Dioxide Partial Pressure|
It is also possible to acquire other signals such as temperature. The maximum number of signals is 8 or 16 depending on the hardware used.
