A measuring device includes a measuring part that performs an invasive blood pressure measurement using a transducer and detects that a blood pressure measured by the invasive blood pressure measurement becomes a predetermined abnormal state during the invasive blood pressure measurement, a detecting part that detects whether or not a zero-point calibration of the transducer is being carried out, and a notification control part that controls whether or not to output an alarm based on a detection state of the detecting part when the blood pressure becomes the predetermined abnormal state.
