The residual volume is a direct measurement of the amount of air left in the lungs after maximal expiration.
Patients with kyphosis typically have a large functional residual capacity due to inability to forcefully exhale.
Emphysematous patients usually have a large TLC and normal FEV1.
Patients with fibrotic lung disease characteristically have a reduced VC and normal FEV1/FVC.
Obstructive lung disease is always associated with a large functional residual capacity.
Question 2: Which of the following statements is true regarding pulmonary diagnostic testing?
Sarcoidosis and abestosis are two entities which reduce DLCO.
A reduced DLCO is an important cause of hypoxemia.
Postoperative FEV1 does not predict complication rate in older patients.
A PVR less than 190 dynes during exercise is not associated with improved survival.
Blood lactate levels during exercise can predict pulmonary complications.
Question 3: Which of the following statements is true regarding bronchoscopy?
The most common indication for diagnostic bronchoscopy is interstitial lung disease.
Hemoptysis lasting longer than 1 week with a normal chest film is an indication for bronchoscopy.
Biopsy of a bronchial orifice spur gives excellent yield for peribronchial tissue.
Flexible bronchoscopy is less useful than rigid bronchoscopy for upper lobe lesions.
Bronchial washings and brushings do not increase diagostic yield in submucosal carcinoma.
