305 Approach to the Patient with Disease of the Respiratory System Flashcards
The majority of diseases of the respiratory system fall into one of three major categories:
(1) obstructive lung diseases; (2) restrictive disorders; and (3) abnormalities of the vasculature.
name the right category to the disease. Bronchiectasis Bronchiolitis Desquamative interstitial pneumonitis (DIP) Bronchitis Bronchogenic carcinoma
Bronchiectasis
Bronchiolitis—- Obstructive lung disease
Desquamative interstitial pneumonitis (DIP)—Restrictive pathophysiology—parenchymal disease
Bronchitis—Infectious diseases
Bronchogenic carcinoma—Malignancy
cardinal symptoms of respiratory disease are:
dyspnea and cough
Define chronic cough.
persisting for more than 8 weeks
Hemoptysis can be a symptom of which lung diseases?
infections of the respiratory tract, bronchogenic carcinoma, and pulmonary embolism
what do you search in inspection of the respiratory system?
using accessory muscles of respiration to breathe; severe kyphoscoliosis (restrictive pathophysiology); inability to complete a sentence in conversation.
Clubbing can be found in which lung diseases?
cystic fibrosis, IPF, and lung cancer
Which lung disease causes Pulso paradoxus?
COPD
Cyanosis is seen to which values of deoxygenated hemoglobin/dL?
less than 5 g of deoxygenated hemoglobin/dL
Explain: ([A–a]DO2
measurement of arterial PO and the calculation of an alveolar gas and arterial blood oxygen tension difference ([A–a]DO ). Patients with diseases that cause ventilation perfusion mismatch or shunt physiology have an increased (A–a)DO at rest.
What does it mean to have a total lung capacity less than 80%
defines restrictive pathophysiology
Restriction with impaired gas exchange, as indicated by a decreased D CO, suggests which group of lung diseases?
parenchymal lung disease
