Lung pulse

This image shows cardiophasic movement of the pleural line that is termed lung pulse. Cardiac contraction is sufficiently forceful as to move the lung in synchrony with the cardiac cycle. This movement is readily detected as cardiophasic movement of the pleural line. It has the same implication as detection of respirophasic movement of the pleural line which termed lung sliding (ie, there is no pneumothorax at the site of probe application on the chest wall).
