Impulse oscillometry (IOS), also known as respiratory oscillometry, forced oscillatory technique (FOT), or just oscillometry, is a non-invasive lung function test that measures the mechanical properties of the respiratory system, particularly the upper and intrathoracic airways, lung tissue and chest wall, usually during the patient's tidal breathing (the way someone breathes when they are ...

Place the bony parts of the palm around the borders of the patient's scapulae while he or she says "ninety-nine" or "one one one" to test for fremitus. Repeat the sequence on the front of the chest. A decrease in fremitus may be observed if the patient has a soft voice, obstructed bronchus, COPD , pneumothorax , or other disease or injuries ...
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
