Abstract
<p>Respiratory impedance measured by forced oscillation technique has been evaluated by average values during inspiratory and expiratory phases. However, it is well known that the impedance changes according to the airflow rate of a subject which changes during respiratory cycle. We should treat the impedance data as temporal data like electrocardiogram. Furthermore, the value of respiratory impedance is influenced by the heart beat which compresses the large airway located near the heart. Therefore, we should cancel the influence by heart beat in order to obtain precise information from the impedance data. We performed simultaneous recording of the respiratory impedance (MostGraph, Chest corporation, Japan) and finger-tip volume pulse wave (BSM-2353, NihonKoden, Japan), and obtained novel analysis methods for respiratory mechanics during rest breath.</p>
