Acute Pulmonary Flashcards
Atelectasis (not super concerning)
Small airway collapse (prolonged dependency of lower lobes)
When is atelectasis common?
Post surgery (obesity is greater risk)
What are symptoms of atelectasis?
Fever
Tachypnea
Tachycardia
Scattered rales (Velcro noise)
Decreased breath sounds
What can happen if atelectasis persists for > 72 hours?
Likely to develop pneumonia
How is atelectasis easily preventable?
Taking full deep breaths (10 an hour)
Early mobilization
Frequent changes in position
Encouragement to cough
Acute bronchitis
Acute inflammation of the large airways of lungs (95% due to virus)
When does acute bronchitis become more likely?
During flu season (fairly common, can lead to secondary pneumonia)
What are symptoms of acute bronchitis?
Productive cough
Malaise
Difficulty breathing
Wheezing
Pneumonia
Acute inflammation of the lungs due to infection or inability to keep lower respiratory tract clean
When does pneumonia occur?
When the infection gets past the mucociliary elevator
Why are the lungs an ideal breeding ground for pathogens in pneumonia?
Moist warm environment
What are the types of pneumonia?
Community acquired
Health care associated
Ventilator associated
How can you prevent pneumonia?
Flu vaccine
Clean equipment
Wash hands
Position in semirecumbent position
Activity helps clean lungs
What is the onset of bacterial pneumonia?
Abrupt
What is the key sign of bacterial pneumonia?
Productive cough
What will you see on imaging for bacterial pneumonia?
Lobar segmental consolidations
Pleural fluid
What are the 4 stages of bacterial pneumonia?
Congestion (24hrs)
Red hepatization (2-3 days post consolidation)
Grey hepatization (2-3 days post RH)
Resolution (2-3 days post GH)
What is consolidation in the lungs?
Region of normally compressible lung tissue that has filled with liquid instead of air
What does the lung look like in the red hepatization phase?
Consistency of the liver due to hyperemia and exudate in the lungs
What is the onset of viral pneumonia?
Insidious (gradual)
What is on imaging for viral pneumonia?
Diffuse airway changes
Bronchiolitis obliterans
Acute inflammatory injury due to a diffuse destruction of bronchioles
What causes bronchiolitis obliterans?
Infection
Toxic gas exposure
Collagen disorder
Chronic bronchitis
Why do pediatrics get bronchiolitis obliterans?
Severe lower respiratory airway infection
Cryptogenic organizing pneumonia
Diffuse interstitial lung disease that primary affects the alveolar walls (also affects distal bronchioles, respiratory bronchioles, and alveolar ducts)
What is pleural effusion?
Excessive collection of fluid between the parietal and visceral pleura
