1. A hypoventilation monitoring system comprising:
a sensor box configured to measure an EIT data on a chest of a subject and transmit the measured EIT data in real-time; and
a hypoventilation monitoring unit configured to receive the EIT data from the sensor box, monitor a hypoventilation condition of the subject by using the received EIT data, and display the monitoring result for the hypoventilation condition,
wherein the hypoventilation monitoring unit comprises:
an EIT data processing unit configured to detect a ventilation condition information comprising an air distribution, volume change, or combinations thereof inside lungs from the EIT data;
a ventilation parameter calculation unit configured to calculate a ventilation parameter comprising tidal volume, minute ventilation, or respiratory rate by analyzing the detected ventilation condition information;
a hypoventilation determination unit configured to determine a hypoventilation condition by comparing the calculated ventilation parameter with a hypoventilation reference value; and
a display control unit configured to control a display to display at least one of the calculated ventilation parameter or the monitoring result for the hypoventilation condition.
