HSE-HA HAEMODYN

  • 16-channel data acquisition software for haemodynamic experiments
  • For Windows® 2000, NT and XP
  • To measure signals such as left ventricular pressure, aortic pressure, aortic flow, atrial pressure, atrial flow, coronary flow, length measurement, pO2, pCO2, pH, temperature, etc.
  • Easy to use, reduced settings by using configuration files
  • Storage of raw data with possibility for replay — complete experiments can be replayed
  • Indication of the measured signals and parameters online in numerical tabular form or graphical detail and trend windows
  • Allows data exchange interface by converting the data into the ASCII delimited format
  • Monitors the experimental sequence by placing event markers and concentration information
  • Very easy graphical selection of specific data points by cursors for evaluation, data reduction and export
  • Export of a raw data sequence into ASCII delimited format

The HSE-HA HAEMODYN software can be adapted to virtually any experimental investigation for haemodynamic experiments. Acquisition can cover signals such as left ventricular pressure, aortic pressure, aortic flow, atrial pressure, atrial flow, coronary flow, segment length and wall thickness measurement, 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, contractility index CI, minimal, maximal, and mean flows, etc. During data acquisition, all acquired signals and derived
parameters are stored on the hard disc and can be displayed on the screen.
The HSE-HA HAEMODYN software is available in a basic version which includes the minimal necessary algorithms that can be upgraded to a more complex system including all the available algorithms. The configuration of the system is defined in configuration files to reduce the amount of settings necessary and to ensure a stable and secure system. The user only needs to calibrate the signals and fix the graphics scaling. All the hardware definitions and algorithms used are defined in the configuration files. This reduces the amount of information necessary in the SOP's and the possibility of wrong settings. The configuration files can be changed and the software used in combination with a set of different configuration files to match the different experiments.HAEMODYN is a menu-controlled software and employs special algorithms to calculate the standard haemodynamic parameters.
The HSE-HA HAEMODYN software has a maximum of 16 channels, i.e. up to 16 different raw signals can be handled. The assignment of the signals to the individual channels is determined in the configuration files. The sample rate, the type of signals and the algorithm used for analysis are also defined in the configuration file. The arrangement of the graphic detail (raw signals) and trend (calculated parameters) is defined in the menu. The user has only to set up which of the available signals he wants to acquire and display, which of the possible parameters he wants to evaluate and display, enter the experimental protocol, and finally calibrate before he starts the data acquisition.
