- A pneumothorax (pneumo- + thorax; plural pneumothoraces) is an abnormal collection of air or gas in the pleural space that causes an uncoupling of the lung from the chest wall. Like pleural effusion (liquid buildup in that space), pneumothorax may interfere with normal breathing.

Practice Essentials Background. Pneumothorax is defined as the presence of air or gas in the pleural cavity (ie, the potential space between the visceral and parietal pleura of the lung). The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation.

- A spontaneous pneumothorax, also referred to as a primary pneumothorax, occurs in the absence of a traumatic injury to the chest or a known lung disease. A secondary (also termed complicated) pneumothorax occurs as a result of an underlying condition.

- When the pneumothorax is due to an underlying lung condition such as emphysema, it is known as a secondary spontaneous pneumothorax. In this, the emphysematous blebs are larger and known as bulla. There are different types of pneumothorax, each defined by its cause: 1  Primary spontaneous pneumothorax occurs when you don’t have an underlying lung disease. It is often caused by the rupture (bursting) of an air-filled sac in the lung, called a bleb or bullae.

How much does a cigarette weigh? This is an experiment I did...I'd say coming up for nearly 2 years ago. Interested in the economics of rolling ones own cigarettes (tobacco is bad mmmkay?) I weighed a 'tailor made' cigarette as a whole (paper + filter) and then just the tobacco contained within.

What is spontaneous pneumothorax? A spontaneous pneumothorax is the sudden onset of a collapsed lung without any apparent cause, such as a traumatic injury to the chest or a known lung disease. A collapsed lung is caused by the collection of air in the space around the lungs.

Collapsed Lung (Pneumothorax) There are two types of pneumothorax, tension and simple. Tension pneumothorax. 1  This refers to a condition in which air builds up under pressure and usually totally collapses one or both of the lungs. 2  This causes severe dysfunction of the cardiovascular system.

Pneumothorax (Tension) Tension pneumothorax is accumulation of air in the pleural space under pressure, compressing the lungs and decreasing venous return to the heart. (See also Overview of Thoracic Trauma.) Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve).

Tension Pneumothorax Classical management of tension pneumothorax is emergent chest decompression with needle thoracostomy. A 14-16G intravenous cannula is inserted into the second rib space in the mid-clavicular line. The needle is advanced until air can be aspirated into a syringe connected to the needle.

- Spontaneous pneumothorax is more common in men. Smoking has been shown to increase the risk for spontaneous pneumothorax. In some instances, the lung continues to leak air into the chest cavity and results in compression of the chest structures, including vessels that return blood to the heart.

Collapsed Lung (Pneumothorax) Pneumothorax: Free air in the chest outside the lung. Pneumothorax can occur spontaneously, follow a fractured rib or other trauma, occur in the wake of chest surgery, or be deliberately induced in order to collapse the lung.

Collapsed Lung (Pneumothorax) This result is called a pneumothorax, which is the medical term for a collapsed lung. There are two types of pneumothorax, tension and simple. Causes of collapsed lung include trauma to the chest cavity (fractured rib, penetrating trauma from a bullet, knife, or other sharp object), cigarette smoking, drug abuse, and. certain lung diseases.

Collapsed Lung (Pneumothorax) The primary cause of a pneumothorax is trauma to the chest cavity. A fractured rib, for example, could puncture the lung. Moreover, penetrating trauma from a bullet, knife, or other sharp object can directly puncture the lung. Sometimes, very tall, thin people are prone to a spontaneous pneumothorax.

- 1 Conditions that cause abnormal tissue growth in your lungs can cause a spontaneous pneumothorax. Pulmonary fibrosis occurs with an overgrowth of tissue in the lungs and may lead to a pneumothorax.  Cancer: A tumor in your lung may lead to a pneumothorax.

Pneumothorax A pneumothorax is an abnormal collection of air in the pleural space that causes an uncoupling of the lung from the chest wall. Like a pleural effusion (liquid buildup in that space), a pneumothorax may interfere with normal breathing. Symptoms typically include chest pain and shortness of breath. It is often called a collapsed lung, although that term may also refer to atelectasis. One or both lungs may be affected.

pneumothorax Etymology: Gk, pneuma, air, thorax, chest. the presence of air or gas in the pleural space, causing a lung to collapse. Pneumothorax may be the result of an open chest wound that permits the entrance of air, the rupture of an emphysematous vesicle on the surface of the lung, or a severe bout of coughing. small pneumothorax may resolve on its own, but most require medical treatment. The object of treatment is to remove air from the chest and allow the lung to re-expand. This is done by inserting a needle and syringe (if the pneumothorax is small) or chest tube through the chest wall.

Pneumothorax Clinical Presentation Signs and symptoms of tension pneumothorax are usually more impressive than those seen with a simple pneumothorax, and clinical interpretation of these is crucial for diagnosing and treating the condition. Tension pneumothorax is classically characterized by hypotension and hypoxia.

Other Lung Conditions Pneumothorax. A pneumothorax is a rupture of the air sacs, or alveoli, in the lung. As the baby breathes air into the lungs, some of that air goes through the rupture and into what is called the pleural space or cavity that surrounds the lung.The air that enters this cavity puts pressure on the lung from the outside, squeezing and squashing the underlying lung, making breathing more difficult.s the baby breathes air into the lungs, some of that air goes through the rupture and into what is called the pleural space or cavity that surrounds the lung.

Overview Symptoms. The main symptoms of a pneumothorax are sudden chest pain and shortness of breath. But these symptoms can be caused by a variety of health problems, and some can be life-threatening. If your chest pain is severe or breathing becomes increasingly difficult, get immediate emergency care.

Learn how UpToDate can help you. Pneumothorax is defined as a collection of air that is located within the thoracic cage between the visceral and parietal pleura (image 1). Air can enter the pleural space through a leak in either pleural surface. It may flow freely within the chest or be loculated by fibrous bands or other tissues.

What is spontaneous pneumothorax? A spontaneous pneumothorax is the sudden onset of a collapsed lung without any apparent cause, such as a traumatic injury to the chest or a known lung disease. A collapsed lung is caused by the collection of air in the space around the lungs.lacement of a chest tube can help release the air that has collected in the space around the lung and allow the lung to re-expand. 1 of 1. Patients who seek treatment for minimal or resolving symptoms after more than 24 hours will receive a chest X-ray to determine treatment.

Pneumothorax A pneumothorax (PTX) is defined as air that has leaked into the pleural space, either spontaneously or as a result of traumatic tears in the pleura following a chest injury. Chest trauma sustained in sporting occurs infrequently.

Hazard Communication 2012 (HazCom 2012)/GHS Update: Pyrophoric Gases, Simple Asphyxiants, and Combustible Dusts Simple Asphyxiant – OSHA defines a simple asphyxiant as “A substance or mixture that displaces oxygen in the ambient atmosphere, and can thus cause oxygen deprivation in those who are exposed, leading to unconsciousness and death.”

Collapsed Lung (Pneumothorax) 1 Air usually enters this space, called the pleural space, through an injury to the chest wall or a hole in the lung. 2  This result is called a pneumothorax, which is the medical term for a collapsed lung.
