A new computerized data acquisition system collects over fifty physiologic variables from multiple monitors. This inexpensive, transportable system enhances clinical investigation data recording and analysis.

Area of Science:

  • Biomedical Engineering
  • Clinical Informatics

Background:

  • Clinical investigations require accurate and efficient data acquisition from diverse physiologic monitors.
  • Existing systems may lack flexibility, portability, or cost-effectiveness for comprehensive data collection.

Purpose of the Study:

  • To describe a novel computerized data acquisition system for clinical investigation.
  • To detail its capabilities in recording multiple physiologic variables from various electronic monitors.

Main Methods:

  • Utilizes a personal computer with RS-232C serial communications and analog-to-digital conversion.
  • Software is adaptable for various physiologic monitors, including Spacelabs, Hewlett-Packard, SARA mass spectrometer, and Nellcor pulse oximeter.
  • Records both parameter and waveform data, storing it in accessible files.

Main Results:

  • The system can record over fifty physiologic variables from up to twenty-four electronic monitors.
  • Successfully integrated with multiple specific medical devices (e.g., Spacelabs, Hewlett-Packard, Nellcor).
  • Generated data files are compatible with standard graphical and statistical software packages.

Conclusions:

  • The described system offers an easy-to-use, transportable, and inexpensive solution for clinical data acquisition.
  • Its flexible software design allows for adaptation to a wide range of physiologic monitoring equipment.
  • Facilitates enhanced data recording and analysis in clinical research settings.
