Pathologies Flashcards
What is a pneumothorax?
Where air leaks into the pleural cavity, which is the space between the lung and chest wall. This air pushes on the outside of the lung and makes it collapse. Pneumothorax can be complete lung collapse or a portion of the lung.
What is a tension pneumothorax?
If air continues to enter the pleural cavity as someone breathes, this can start to compress the other lung and heart leading to a tension pneumothorax and can be life threatening.
What is a primary spontaneous pneumothorax?
develops in a healthy young person for no reason and occurs due to a small tear in the lung, probably due to a weakness when developing.
What is a secondary pneumothorax?
develops in someone which an existing lung condition, usually COPD, were the condition weakens the lungs and it is more likely to tear. It can also occur because of lung cancer, cystic fibrosis, TB and idiopathic pulmonary fibrosis
What are the symptoms of a pneumothorax?
Feeling breathless and a sudden sharp stabbing pain on one side of the chest that gets worse when you breathe in.
What is the treatment of a pneumothorax?
If its small it can heal itself.
For a larger pneumothorax, it may be aspirated which involves inserting a needle into the air filled space and sucking the air out through a thin tube using a syringe.
Or, a chest drain may be used which is inserted through the chest wall and allows air out but not back in, so the lung can re-inflate. It is usually in place for 2-5 days.
What is an atelectasis?
Where the airways and air sacs in the lungs collapse or do not expand properly. It can occur when there is an airway blockage, when pressure outside the lung keeps it from expanding or when there is not enough surfactant for the lung to expand normally.
Who is at higher risk of an atelectasis?
Patients may be at higher risk of an atelectasis if they are obese, have asthma, COPD, cystic fibrosis or if they have recently had surgery as anaesthetic can affect the way the lungs work.
What can cause an atelectasis?
can occur in newborns whose lungs are not fully developed and have respiratory distress syndrome. Can occur when a tumor, excess mucus or food blocks the airway or due to a pneumothorax or pleural effusion.
What are the symptoms of an atelectasis?
It may not cause any signs or symptoms if it affects a small area of your lungs. If it affects a larger area then symptoms can include shallow breathing, wheezing, coughing and fever.
What is the treatment of an atelectasis?
Chest physiotherapy= postural drainage, percussion, spirometry and ACBT.
Surgery= removal of airway obstructions may be done by suctioning mucus or by bronchoscopy, where a tube is placed down the throat to clear the airways.
Continuous positive airway pressure (CPAP) may be helpful in some people who are too weak to cough and who have hypoxemia after surgery.
What is pleural effusion?
Is a build up of fluid between the two layers of pleura.
When is a plural effusion most likely to occur?
Pleural effusions are common and are often due to lung infections, such as pneumonia and heart failure. A pleural effusion can also be a symptom of several types of cancer as cancer cells can spread into the pleura, which can lead to irritation and cause fluid to build up.
What are the symptoms of a plural effusion?
Breathlessness, cough, chest pain.
How are pleural effusions usually treated?
chest drain
