Abstract
Objectives
Bedside presentation of physiologic data is central to modern critical care. Waveform displays (such as electrocardiogram) and simple time-averaged data (such as heart rate) have been the basis for decision-making for at least 4 decades. Whether these displays provide the optimal data synthesis is unknown. As computer storage has become less expensive, waveform data have started to become archived. However, the technology of recording and archiving physiologic signals has advanced faster than the technology of playing them back, which has attracted only a limited attention.
Methods
We present multi wave animator (MWA)—a set of open-source MATLAB scripts aimed to create dynamic visualizations (eg, video files in AVI format) of patient physiologic signals recorded from bedside (intensive care unit or OR) monitors. The source code of MWA is freely available online (www.burykin.com/mwa/
) together with a detailed tutorial and sample data sets.
Results
Multi wave animator creates animations in which physiologic signals are displayed to mimic their appearance on current bedside monitors. Thus, clinically relevant information is presented in a format familiar to clinicians. Moreover, MWA can be used to create animations that include many advanced features, such as dynamic visualization of HRV indices or vital sign sonification.
Conclusions
The MWA framework remains a working prototype (proof of principle); however, it can readily be used to construct and experiment with different types of physiologic signal display. Possible applications of MWA include clinical research, education, patient safety, and quality control.
