Study Description

Brief Summary

Our objective is to develop intuitive, meaningful and ergonomically efficient informative displays specific to the user's domain. Specifically we aim to enhance and refine the display prototype of ABG information to include gas-exchange, acid-base balance, lung mechanics, ventilation, oxygenation, and metabolism information.

Healthy	Behavioral: New ICU Display Visualization

Detailed Description

To create an intuitive and meaningful visualization of Arterial Blood Gas (ABG) variables, it is necessary to address usability, ergonomics, domain specific, and expertise specific issues and concerns. Our objective is to develop intuitive, meaningful and ergonomically efficient informative displays specific to the user's domain. Specifically we aim to enhance and refine the display prototype of ABG information to include gas-exchange, acid-base balance, lung mechanics, ventilation, oxygenation, and metabolism information.

Arm

Intervention/Treatment

Simulator Group - With Display

ICU nurses who viewed the new ICU display visualization

Behavioral: New ICU Display Visualization

Simulator Group - Without Display

ICU nurses who did not view the new ICU display visualization, but instead viewed a traditional "spreadsheet" style presentation of ICU trends of data

Outcome Measures

Primary Outcome Measures

Nurses using the new ICU display will detect and communicate to an attending physician (confederate) more abnormal patient physiological states than when using the tabular (control) display. [At time of observation]
