What is the #1 reason, generally, for hemoptysis
Bronchitis. Cancer next
What is the most important factor used in the "Port" criteria for determining risk in pneumonia
Age
If FEV is low then what?
Think obstructive
If FVC is low then what?
Think Restrictive
What is the purpose of spirometry
provides information about obstructive or restrictive air flow; used to support the diagnosis of COPD and chronic restrive pulmonary disease
What is FVC (forced vital capacity)
amount of air that can be forcefully expelled from a maximally inflated lung position.
What is forced expiratory volume in 1 second (FEV1)
volume of air expelled during 1st sec of FVC. In obstructive it is less than predicted value.
What is FEV1 / FVC
ratio of FEV1 to FVC. In healthy adults should be 75+
If FEV1 / FVC lower than predicted than think what?
obstructive
If FVC is decreased think what
restrictive: although, normal or decreased can also be obstructive
If FEV1 is decreased think what
obstructive but restrictive can also be normal or decreased
If FEV1 / FVC ratio is decreased then think what?
obstructive
If Total lung capacity is normal or increased then think what
obstructive
If total lung capacity is decreased then think what
restrictive
Where does lung cancer metastasis to?
brain, liver, bone and adrenals
What are the 2 primary classifications of Lung cancer
bronchogenic 95%, and alveolar cell
What are the 4 primary types of bronchogenic carcinomas
squamous cell, small cell (oat cell) adenocarcinoma and large cell
What are some early signs of squamous cell cancer
cough and sputum
What are some late signs of squamous cell cancer
hemoptysis, CP, pneumonia, dyspnea, wt loss, obstructive phenomenon
What radiological findings might you see for squamous cell cancer
central lesion most common. Peripheral lesions larger than other primary lung cancers, commonly found in upper lobe
How would you diagnose squamous cell cancer
sputum cytology, bronchial washings and biopsy
What are early and late signs of large cell cancer
early: cough, sputum. Late: hemoptysis, CP, pneumonia, dyspnea, wt loss, obstructive phenomenon
What radiologic findings might you see with large cell cancer
central lesion in 40%
What clinical findings might you see with oat cell cancer
early: cough, sputum. Late: hemoptysis, CP, pneumonia, dyspnea, wt loss, obstructive phenomenon
What radiologic findings might you see with oat cell cancer
hilar and peripheral lesions common, may have mediastinal widening
How would you diagnose oat cell cancer
sputum cytology, bronchial washings and biopsy
What kind of lung cancer is associated with "coin" lesions
adenocarcinoma
Which kind of lung cancer is known as the "silent" cancer and typically found on routine CXR
adenocarcinoma
Define solitary pulmonary nodules
single; radiogrphically visible lesion that is within and surrounded on all sides by pulmonary parynchama
Name 3 common benign lung tumors
hamartoma, fibroma, chondroma
