Aberdeen polygons: computer displays of physiological profiles for intensive care

Article Abstract:

Polygon patterns are useful for information gathering about the physiological state of patients, especially, in the intensive care units. Each side of an Aberdeen polygon denotes a norm for an important sign. Deflections from the norm are represented by triangles extending from the side of the polygon. Triangles extending inward indicate negative deviations and triangles extending outward indicate positive deviations from the norm. Diagnosis of the nature and the severity of a patient's physiological state becomes easier after physicians learn to recognize the patterns.

Preferred viewing distances for handheld and structurally fixed displays

Article Abstract:

Differences observed across variable handheld and structurally-fixed hardcopy display configuration conditions were consistent and statistically significant. On assessing the potential relationship between observed distance and individual resting point accommodation, it was found that there was no apparent relationship between the two. These results suggest that simple eye-to-display viewing distance is fundamentally different for text presented in a configuration similar to that of a video display terminal and for handheld text presentations.

Physiological model of CO2 output during incremental exercise

Article Abstract:

A physiological model that explains carbon dioxide (CO2) pathway during incremental exercise was studied with the use of experimental data from trained athletes subjected to incremental exercises. Work loads were given by a Bicycle ergometer. A model illustrating the pathway of CO2 output was created. The model was found to have four essential features, one of which is the use of blood CO2 dissociation curve as the vector to transport CO2 from tissue to the lungs.
