Pneumonia caused by entrance of foreign particles aspirated into the lower respiratory tract
A glandular tumor, either benign or malignant, situated in the submucosal tissues of large bronchi
Chronic dilation of the bronchi, with inflammation and destruction of bronchial walls and cilia
Carcinoma of the lung that arises from the epithelium of the bronchial tree
most often arises from long-term, heavy cigarette smoking or prolonged exposure to high levels of industrial air pollution, which irritates the mucous lining of the bronchial tree and increases susceptibility to both bacterial and viral infections
What does the respiratory system do?
distributes air for gas exchange with the circulatory system
Which pleura adheres directly to the lung tissue?
What are the only paranasal sinuses present at birth?
maxillary and ethmoid
What is most frequently performed exam in the radiology department?
chest x ray
What are the 2 standard projections for chest radiography?
Erect PA and Left Lateral
What is the most common complaints of radiologists?
poor exposure technique
What is mediastinal emphysema?
Occurs when there has been a disruption in the esophagus or airway and air is trapped in the mediastinum and can be caused by chest trauma, endoscopy, or violent vomiting.
What is the sail sign?
Normal enlargement of the thymus in infants that shows up in both frontal and lateral projections of a chest radiograph
Where are Hickman catheters placed?
open the the outside of the body with the tip of the catheter placed in the superior vena cava
lack of respiratory function or the lack of oxygen and carbon dioxide exchange
denotes low oxygen levels withing the arterial blood and is caused by toxic gas or smoke inhalation, high altitudes, hypoventilation, or impaired diffusion(a physical seperation of gas and blood)
the inability to move air into and out of the lungs, with consequent increased blood carbon dioxide content
is a generalized disorder resulting from a genetic defect transmitted as an autosomal recessive gene that affects the function of exocrine glands. In chromosome 7, affects mainly white children, and the life span is between 20 and 30.
also known as respiratory distress syndrome, affects infants and is a disorder of prematurity or infants born at less than a 37-week gestation
Hyaline Membrane Disease
is the most frequent type of lung infection, resulting in an inflammation of the lung (pneumonitis) and comprised pulmonary function
is the most common bacterial pneumonia because this type of bacteria is often present in healthy throats, generally affecting a whole lobe of the lung
occurs sporadically except during epidemics of influenza, when secondary infection with staphylococci is common
a thin-walled, air-containing cyst, characteristic radiographic lesion and is more typically seen in children
is even rarer pneumonia accounting for less than 1% of all hospital admissions for acute bacterial pneumonia
can be caused by various viruses, most commonly influenza A and B. It is more common that bacterial pneumonia but less severe
is a permanent, abnormal dilation of one or more large bronchi as a result of destruction of the elastic and muscular components of the bronchial wall
is an infection caused by inhalation of Mycobacterium tuberculosis, may also affect genitourinary, skeletal, and central nervous systems
refers to a group of disorders that cause chronic airway obstruction. The most common forms are chronic bronchitis and emphysema
Chronic obstructive pulmonary disease
What is the predominant risk factor associated with COPD?
is a condition in which the lung's alveoli become distedned, usually from loss of elasticity or interference with expiration
are occupational diseases in which inhalation of foreign inorganic dust from a particular work environment results in pulmonary fibrosis
the oldes known pneumoconiosis, results from inhaling silica (quartz) dust and is common among miners, grinders, and sandblasters.
or black lung disease, results from inhalation of coal dust over an extended period of about 20 years. As the coal dust is deposited in the lungs, "coal macules" develop around the bronchioles and cause their dilation.
results from the inhalation of asbestos dust, which can cause chronic injury to the lungs. Asbestos dust is found in building materials and insulation.
a rare malignant neoplasm of the pleura, caused by high exposure to asbestos and develops at least 15 years later.
is a systemic fungal infection caused by a fungus that thrives in soil, especially that fueled by bird or bat excreta
a systemic, fungal infection that is caused by a fungus that thrives in semiarid soil, particularly the southwestern United States and northern Mexico.
is a localized area of dead(necrotic) lung tissue surrounded by inflammatory debris
an accumulation of pus in the pleural cavity, usually caused by some primary lung infection
inflammation of the pleura and is often indicative of a serious condition such as pneumonia, pulmonary embolism, TB, or malignant disease
excess fluid collects in the pleural cavity and is a frequent manifestation of serious thoracic disease, usually pulmonary or cardiac in origin
a pleural effusion containing blood
the second most common radiographic presentation of a neoplasm consists of a solitary radiopaque lung nodule
What are the 5 different routes a malignancy is spread to the lungs?
1) through the bloodstream in hematogenous metastases
2) through the lymph system in lymphogenous metastases
3) by direct extension in local invasion
4) through the tracheobronchial system in bronchogenic mestastases
5) direct implantation from biopsies or other surgical procedures

What is an endotracheal tube?
A tube inserted through the nose or mouth into the trachea and used to manage the patient's airway

Where is a port-a-cath placed?
Under the skin, just below the clavicle, not open to the outside, less likely to become infected

Is made up of lipids, proteins, and carbohydrates; coats the alveoli of the lungs to Reduce surface tension and prevents the collapse of the alveoli
