absent breath sounds

The lack of perceptible sounds of airflow during auscultation of the patient's chest.


Absent breath sounds can be caused by a lack of breathing (apnea) or by lung disorders that block the transmission of the sounds to the surface of the chest, e.g., pneumothorax, pleural effusion.
