pneumothorax: condition in which an injury to the chest wall penetrates the parietal pleura or damages the alveoli and the visceral pleura allows air into the pleural cavity. The result is an atelectasis, or a collapsed lung. Treatment involves removing all of the air before closing the opening. pneumothorax: condition in which an injury to the chest wall penetrates the parietal pleura or damages the alveoli and the visceral pleura allows air into the pleural cavity.

What else can I help you with?
What is the presence of air or gas in the pleural cavity?
Pneumothorax-presence of air or gas in the pleural cavity.
What does blood and air in pleural cavity mean?
Blood or air in the pleural cavity indicates a medical emergency. Blood in the pleural cavity suggests injury or bleeding within the chest, while air in the pleural cavity can indicate a collapsed lung or pneumothorax. Both conditions require urgent medical attention to prevent serious complications.
What is the pressure between the external air and the pleural cavity when inhalation just begins?
No
If the chest drain comes out of the chest does the hole in the chest wall need to be covered immediately so that it is air tight and to prevent air getting into the pleural cavity?
The hole must be covered as soon as possible. Otherwise, the air enters to the pleural cavity.
Does the pleural membrane hold the lungs air tight?
Yes, the pleural membrane helps create a seal around the lungs, which assists in maintaining their inflation by creating negative pressure in the pleural cavity. This negative pressure allows the lungs to expand during inhalation and prevents them from collapsing.
What are some risks associated with pleural biopsy?
Potential complications of this procedure include bleeding or injury to the lung, or a condition called pneumothorax, in which air enters the pleural cavity (the space between the two layers of pleura lining the lungs and the chest wall).
What organ is located in the pleural cavity?
The pleural cavity, also known as the thoracic cavity, is where the lungs and the heart are located.
What is the pressure difference between the external air and pleural cavity when inhalation just begins?
At the start of inhalation, the pressure in the pleural cavity is normally about 756 mmHg, while the external air pressure is about 760 mmHg. This creates a pressure difference of 4 mmHg, causing air to flow into the lungs.
Why hyperresonant note in pneumothorax?
When we percuss vibrations are set up on chest wall which is normally dampened by the lung parenchyma which is porous n we get resonant note...in pneumothorax there is air in the pleural cavity which offers least resistance to these vibrations..n hence we get hyperresonant note..in pleural effusion if fluid is present it offers max resistance n we get stony dullness
What is complication of thoracentesis?
Complications of thoracentesis can include pneumothorax, which is the collapse of the lung due to air entering the pleural space, and hemothorax, where blood accumulates in the pleural cavity. Other potential complications include infection at the puncture site, visceral injury, and re-expansion pulmonary edema if the pleural fluid is removed too rapidly. It is essential for the procedure to be performed by trained personnel to minimize these risks.
What is the term for the veterinary procedure that involves inserting a needle into the pleural cavity to remove accumulated air or fluid?
This is thoracocentesis.
What is the perfix for the word pneumothorax?
The prefix for the word "pneumothorax" is "pneumo-," which comes from the Greek word "pneuma," meaning air or lung. In this medical term, "pneumo-" refers to the presence of air in the pleural space, while "-thorax" indicates the chest cavity. Together, they describe a condition where air accumulates in the thoracic cavity, potentially leading to lung collapse.
