HSE-HA PULMODYN

  • 16 channel data acquisition software for in vivo respiration experiments
  • For Windows 2000, NT and XP
  • Derives and presents online the standard parameters for respiratory studies (TV, Resp. Rate, Resistance, Compliance) real time
  • possibility of combination with circulatory signals (e.g. LV P, aortic flow)
  • In vivo:
    Bronchodilation test and bronchospasmolytic test on anesthetized animals
    Antiasthmatics test according to Konzett-Roessler (bronchial overflow measurement) or according to Einthoven (tracheal pressure measurement)
    Pulmonary air flow
    Tracheal pressure or esophageal pressure
    Arterial pressure or venous pressure
    pO2, pCO2, pH, temperature etc.

The HSE-HA PULMODYN software can be adapted to virtually any experimental investigation in respiratory experiments. Acquisition can cover signals such as pulmonary air flow, tracheal pressure or esophageal pressure, arterial pressure or venous pressure, pO2, pCO2, pH, temperature etc.
Various parameters can be derived from these signals, e.g. tidal volume, respiration rate, peak inspiratory flow, peak expiratory flow, maximal and minimal tracheal pressure, resistance, compliance, systolic, diastolic and mean values for pressures, dp/dt etc. During data acquisition all acquired signals and derived parameters can be displayed on the screen.
The HSE-HA PULMODYN software is available in a basic version which includes the minimal necessary algorithms for pulmonary mechanics evaluation. It 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 has only to calibrate the signals and to fix the graphics scaling, all the hardware definitions and the algorithms used are defined in the configuration files. This reduces the amount of information necessary in the SOP’s and the possibilities of wrong settings. The configuration files can of course be changed and the software can be used in combination with a set of different configuration files to match the different experiments. PULMODYN is a menu-controlled software and employs special algorithms to calculate the standard pulmonary mechanics parameters.
The HSE-HA PULMODYN software has a maximum of 16 input 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.
