About

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.

Full 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.

Enrollment: 32 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria: ICU nurses Exclusion Criteria: All participants were screened and excluded from participation if they had previously participated in any of graphical display design and feedback sessions when developing the ICU display.

Trial design

32 participants in 2 patient groups

Simulator Group - With Display

Description:

ICU nurses who viewed the new ICU display visualization

Treatment:

Behavioral: New ICU Display Visualization

Simulator Group - Without Display

Description:

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