PULMODYN Data Acquisition Software for Respiratory Experiments

The HA-HSE PULMODYN data acquisition and monitoring software can be adapted to virtually any respiration study experiment, e.g. isolated lungs, airflow and pressure measurements with free breathing or anesthetized animals . Acquisition can cover signals such as pulmonary air flow, tracheal pressure, esophageal pressure. Any blood pressure, ECG or other signals like temperature, pH, pO2 etc, can also be recorded.

Calculated respiration parameters are e.g. Respiration Rate, max inspiratory flow, max expiratory flow, Tidal Volume,  Resistance and Compliance/Conductance etc. User defined parameters can be created by formulas. 

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.

PUMODYN 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.

PULMODYN 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. 

Features

• Easy to Use (comes with predefined settings file if the application is known)
• 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 acquisition, all acquired signals and derived parameters are displayed on screen. All raw data and trend data are stored. Data reduction tools are included. Export of data to any statistical package are possible.

Applications

Commonly Used Signals for In-Vivo Respiratory Experiments are:

• Pulmonary Airflow
• Intrapleural Pressure
• Tracheal Pressure or Oesophageal Pressure
• Arterial Blood Pressure or Venous Blood Pressure (option)
• ECG (option)
