Abstract: A medical examination device can include a stethoscope having a chest piece coupled to at least one ear piece via a yoke. The chest piece can have an acoustic portion configured to interface with a subject's body to provide sounds produced in the body to the ear pieces. The medical examination device can also include a pulse oximeter associated with an oximeter portion of the chest piece. The pulse oximeter can have a light emitter and a photodetector to measure oxygen saturation of the subject's blood. In addition, the medical examination device can include a display for displaying information of the stethoscope and/or the pulse oximeter.
