A new portable physiologic data acquisition system (PDAS) reliably records continuous patient data and clinical events at the bedside. This technology offers accurate, real-time monitoring for critical care research.

Area of Science:

Critical Care Medicine
Biomedical Engineering
Clinical Research Technology

Background:

Physiologic research in intensive care units (ICUs) requires accurate, real-time data acquisition.
Existing systems may lack the capability for synchronous recording of physiologic signals and clinical events.

Purpose of the Study:

To describe and evaluate the reliability of a portable, laptop-based, real-time, continuous physiologic data acquisition system (PDAS).
To assess the PDAS's suitability for bedside physiologic research in ICUs.

Main Methods:

A descriptive report of a newly developed research technology.
The PDAS was tested in adult and pediatric ICUs across three academic hospitals.
Sixty-four critically ill patients (34 adult, 30 pediatric) were included in the study.

Main Results:

Bench and field testing demonstrated 100% accuracy with no data transmission errors.
The PDAS successfully recorded various waveform signals (ECG, respiration, pressures, etc.) and parametric data.
Simultaneous capture of physiologic data and clinical events (e.g., ventilation changes, drug administration) was a key feature.

Conclusions:

The PDAS is a reliable tool for second-to-second recording of physiologic signals and associated clinical events.
This system can serve as a valuable adjunctive tool for clinical physiologic studies in critical illness and injury.
