    <p>Current assessment of postoperative lung function of thoracic surgery patients based on spirometry requires patient’s mechanical effort. Non-invasive impedance pneumography (IP) has the potential to evaluate postoperative patients while alleviating their effort. The objective of this study was to assess the agreement of IP and pneumotachography (PNT) of adult cardiac and pulmonary surgery patients before and after surgery. IP was measured simultaneously with the flow signal from the mouth for one minute. Pearson correlation coefficient and linearity test were used to evaluate the agreement. 324 measurements had r≥ 0.7 and 23 measurements had r<0.7. Linearity studies revealed that the average deviation from the linearity and sample-by-sample difference were similar between the surgery groups. The visualization shows that there is more deviation from the linearity in the lung resection group than in the cardiac surgery group during inspiration. The linearity was similar perioperatively, thus the surgery did not affect the agreement of IP and PNT. The results indicate that IP is potential to be used for evaluation of postoperative lung functions of cardiac and pulmonary patients.</p>
