Abstract

A device for obtaining physiological information including plethysmographs of a medical patient and detecting a condition of pneumonia. The portable pneumonia screening device may include one or more sensors configured to obtain physiological information. The pneumonia screener may provide for methods of selecting and interfaces to assist selecting a patient'"'"'s age group. The screener may match a selected age group from a set of programmed threshold level of oxygen saturation, respiratory, pulse rate, or other physiological parameters to assist pneumonia diagnosis. The pneumonia screener may provide one or more visual and/or audio stimuli, such as an animation, sound or music. The visual and/or audio stimuli may indicate initialization, diagnostic in progress, completion, or other events or progress of events. In some embodiments, the visual and/or auditory stimuli may be used to soothe or intrigue the patient such that patient agitation is reduced during the screening process.
