None:
Subcutaneous emphysema is a well-described and frequently self-limited complication of multiple medical conditions including patients who have undergone the insertion or removal of chest tubes. While typically benign, the extensive collection of soft tissue emphysema in select patients can lead to significant respiratory distress secondary to restricted thoracic wall excursion or laryngotracheal dysfunction due external compression from the subcutaneous gas. In these patients, release of this trapped air via gill-slit incisions of the thoracic wall can be a life-saving intervention. We present the case of a 57-year-old male with a history of a recently removed chest tube who presented with significant respiratory distress and marked dysphonia secondary to severe subcutaneous emphysema who underwent bilateral gill slit incision of his anterior chest with rapid resolution of his symptoms.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
