The present invention is an apnea monitor giving alarm when apnea occurs. It uses new designed gas flow sensor and gas differential flow sensor to detect actual airflow from patients nose and mouth. The gas flow sensor and gas differential flow sensor are evolved from a galvanometer utilizing it's structure for sensitivity. The apnea monitor measures the change of chest volume to detect breathing by a conductive rubber string. The apnea monitor also detects the frequency of baby's movement to predict possible apnea.
