Military critical care air transportation teams (CCATT) have demonstrated reliable capability to evacuate critically injured patients from deployed hospitals. However, these compact medical teams constantly face challenges regarding in-flight assessments that are required to rapidly render appropriate clinical support. An automated physiological data-organizing and information-summary system could present aggregated information from multiple data sources, provide at-a-glance summaries of clinical data and assist with prioritizing care for multiple patients. We designed and implemented a prototype vital sign (VS) viewer specifically designed for this unique and hostile environment.
The CCATT viewer displays multiple monitored patients as a group, using their VS trajectories. It uses highly distinguishable colors (green, yellow and red) to code normal, warning, and alert values. With a set of pre-defined and adjustable thresholds, abnormal VS above/below warning or alert thresholds are filled with yellow and red blocks to help rapidly identify patients who need attention. With longer VS trajectories (up to 72 hours) physiological patterns can be observed at a glance. With interactive design, patient data can be selected for detailed display. All operations can be performed on a touchscreen.
In a noisy, busy and confined transport aircraft, loosely-organized physiological data, over-saturated information delivery, and limited visual assessment may reduce the capability of a small clinical team to recognize changes in physiologic status and prioritize care.

Describe the new knowledge and additional skills the participant will gain after attending your presentation.: The attendee will learn how to organize and visualize multiple physiological data trajectories, especially for displaying in busy and chaotic environment.
