The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode tracing as pleura and lung being indistinguishable as linear hyperechogenic lines and is fairly reliable for diagnosis of a pneumothorax.
In pneumothorax, air is present between the two layers of the pleura and lung sliding on ultrasound is therefore absent. The negative predictive value for lung sliding on ultrasound is reported as 99.2–100% – briefly, if lung sliding is present, a pneumothorax is effectively ruled out. [32]
A small spontaneous pneumothorax will typically resolve without treatment and requires only monitoring. [3] This approach may be most appropriate in people who have no underlying lung disease. [3] In a larger pneumothorax, or if there is shortness of breath, the air may be removed with a syringe or a chest tube connected to a one-way valve ...
Percussion and resonance (the quality and feeling of sound) are used to examine lung movement and possible lung conditions. Specifically, percussion is performed by first placing the middle finger of one hand over the area of interest. The middle finger of the other hand is used to strike the last joint of the placed finger.
Pulmonary ultrasound exam to evaluate for pneumothorax, pleural effusion, pulmonary edema, pneumonia, or other pathology; Identification of large-vessel-occlusion stroke and possible treatment; Fetal monitoring and evaluation in obstetric patients; Assist in procedures (peripheral intravenous access, pericardiocentesis)
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
Commonly used after Percutaneous CT-Guided Lung Biopsies: Saji H, Nakamura H, Tsuchida T, Tsuboi M, Kawate N, Konaka C, Kato H (May 2002).

Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
