Summary
TIDAL (Tools for Intelligent Data Acquisition in the Laboratory) is a portable software package for respiratory physiology data analysis. It simplifies data acquisition and processing for various instruments, enabling detailed breath-to-breath analysis.
Area of Science:
- Physiological measurement
- Software engineering
- Respiratory research
Background:
- Accurate acquisition and analysis of respiratory physiological data are crucial for research.
- Existing systems may lack flexibility or portability for diverse laboratory settings.
Purpose of the Study:
- To introduce TIDAL, a portable software package for respiratory data acquisition and analysis.
- To provide a flexible and user-friendly system for processing physiological signals.
Main Methods:
- TIDAL supports various analog output instruments (flow, volume, concentration).
- It utilizes an Experiment Description Language (EDL) for specifying data channels and calculations.
- EDL includes primitives, a macro processor, and a standard macro library for respiratory variables.
Main Results:
- TIDAL enables users to define data channels and complex breath-to-breath calculations.
- The system facilitates the derivation of primary and secondary respiratory variables (e.g., respiratory quotient).
- Written in C with portable coding practices, TIDAL is designed for modularity and ease of porting.
Conclusions:
- TIDAL offers a versatile and portable solution for respiratory physiological data acquisition and analysis.
- The software enhances research capabilities by simplifying complex data processing tasks.
- Its modular design ensures adaptability across different hardware and operating systems.
