CN: Lung Cancer
Where can it derive?
Actual lung tissue
Bronchi
CN: Lung Cancer
Lung cancer can involve the _____ ,____ and ______nerves due to the proximity
Phrenic n.
Vagus n.
Recurrent Laryngeal n.
CN: Lung Cancer
Treatments include?
Removal of lung (pneumonectomy)
Removal of a lobe (Lobectomy)
Removal of specific bronchopulmonary segment (Segmentectomy)
CN:
What is pleuritis?
Inflammation of the pleura producing a roughness on the lungs making breathing difficult
CN:
When does pulmonary collapse occur?
When enough air enters the pleural cavity to break the surface tension between the two layers of pleura
The elasticity of the lungs causes them to collapse
CN:
When does a pneumothorax occur?
Entry of air into the pleural cavity from a penetrating wound to the thoracic wall or a rupture of a pulmonary lesion into the pleural cavity…
which results in a collapse of the lung
CN:
When does a hydrothorax occur?
Accumulation of excess fluid in the pleural cavity, usually result of fluid escape into the pleural cavity, or pleural effusion
CN:
When does a hemothorax occur?
Accumulation of blood in the pleural cavity,
usually the result of a chest wound
CN:
Describe bronchial asthma
Widespread narrowing of the airways produced by contraction of smooth muscle, edema of the mucosa and mucus in the lumen of the bronchi and bronchioles
CN:
What is a bronchoscopy?
Insertion of a bronchoscope into the trachea to visualize the main bronchi
What does the cartilage on the trachea look like?
C SHAPED
