Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Normal diaphragmatic excursion should be 3–5 cm, but can be increased in well-conditioned persons to 7–8 cm. This measures the contraction of the diaphragm. It is performed by asking the patient to exhale and hold it.
The diaphragm is the most important muscle of respiration, [3] and separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity: as the diaphragm contracts, the volume of the thoracic cavity increases, creating a negative pressure there, which draws air into the lungs.

Axial lower chest CT scan showing bowel herniation due to left diaphragmatic rupture. A CT scan has an increased accuracy of diagnosis over X-ray, [7] but no specific findings on a CT scan exist to establish a diagnosis. [9] The free edge of a ruptured diaphragm may curl and become perpendicular to the chest wall, a sign known as a dangling ...
Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray. [1] Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or ...
Air enters the lungs as the diaphragm strongly contracts, but unlike during traditional relaxed breathing the intercostal muscles of the chest do minimal work in this process. The belly also expands during this type of breathing to make room for the contraction of the diaphragm. [3]
This can be recognized by a slight change of sound when the percussion technique is used during expiration and inspiration in the last intercostal spaces. It is caused by a hyperinflation of the lungs associated with chronic obstructive pulmonary diseases, specially to emphysema. Related findings to emphysema Hoover's sign (lung). [3] [4]
Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand.
Hoover's sign in pulmonology is one of two signs named for Charles Franklin Hoover. [1]It refers to inward movement of the lower rib cage during inspiration, [2] - instead of outward as is normal - implying a flat, but functioning, diaphragm, often associated with COPD. [3]
