Subcutaneous emphysema is not typically dangerous in and of itself, however it can be a symptom of very dangerous underlying conditions, such as pneumothorax. Airway and/or breathing support -- including oxygen via external delivery device or endotracheal intubation (placement of a breathing tube through the mouth or nose into the airway) with placement on a ventilator (life support breathing machine), Chest tube -- tube through the skin and muscles between the ribs into the pleural space (space between the chest wall and the lung) if there is lung collapse, CAT/CT scan (computerized axial tomography or advanced imaging) of the chest and abdomen or area with the subcutaneous air, X-rays of chest and abdomen and other body parts that may have been injured. These include endoscopy (tube into the esophagus and the stomach through the mouth), a central venous line (thin catheter into a vein close to the heart), endotracheal intubation (tube into the throat and trachea through the mouth or nose), and bronchoscopy (tube into the bronchial tubes through the mouth). The air can travel to many parts of the body, including the abdomen and limbs, because there are no separations in the fatty tissue in the skin to prevent the air from moving.[11].

[2], Since mechanical ventilation can worsen a pneumothorax, it can force air into the tissues; when subcutaneous emphysema occurs in a ventilated patient, it is an indication that the ventilation may have caused a pneumothorax. The reason for this is that on X-ray images, the large air pockets give the appearance of the lung disappearing. [5] In spontaneous subcutaneous emphysema, air travels from the ruptured alveoli into the interstitium and along the blood vessels of the lung, into the mediastinum and from there into the tissues of the neck or head.[5]. Subcutaneous (or surgical) emphysema is the presence of gas in the subcutaneous soft tissues, which may be detected clinically by swelling of the affected area and crepitus on palpation. There are several types of emphysema, and most affect the lungs. and transmitted securely. Subcutaneous emphysema is an iatrogenic complication by which air is introduced into the tissues either during or immediately after surgery. [25] Another possible cause is a ruptured trachea.

Unlike other types of emphysema, subcutaneous emphysema does not primarily affect the lungs. With no pleural air collection, the risks of chest drain insertion outweighed its benefits and decompression using a skin incision was adopted.

When it does occur, possible causes include: Macklin published further insights into the pathophysiology of spontaneous Macklin's Syndrome occurring from a severe asthmatic attack. [16] A tension pneumothorax, in which air builds up in the pleural cavity and exerts pressure on the organs within the chest, makes it more likely that air will enter the subcutaneous tissues through pleura torn by a broken rib.
