Exploring auditory displays to support anaesthesia monitoring: Six questions from a research program

Anaesthetists work in a visually and acoustically complex environment from which they must extract information about the well-being of an anaesthetized patient. Many studies have shown that auditory alarms, designed to recall attention to parameters with abnormal readings, have serious limitations. To circumvent this we have been investigating whether continuous auditory information displays, or sonifications, might be more effective. Specifically, we have developed a sonification of respiration (breathing) intended to complement the heart monitor sonification commonly used and have tested its effectiveness in different ways. This report outlines our most important findings to date.
