Amir Sam 2 - Resp Flashcards
What 3 respiratory causes are sudden onset?
PE, foreign body and pneumothorax
What respiratory causes have an onset of minutes?
Airway inflammation or obstruction Chest infection Heart failure
What respiratory causes have an onset of days?
Chronic inflammation / obstruction / infection / heart failure Interstitial lung disease Malignancy Pleural effusion Neuromuscular
Describe the pneumothorax management algorithm
Primary (healthy) < 2cm = discharge with repeat CXR > 2cm = aspiration, if failed then chest drain Secondary (COPD) < 2cm = aspiration > 2cm = chest drain
What is RBBB?
Activation of the right ventricle is delayed as depolarisation has to spread across the septum from the left ventricle
What does RBBB look like on ECG?
MARROW M shaped QRS in V1 -3 W shaped QRS in I, aVL, V5-6 (wide slurred S wave) Broad QRS
How do you determine axis deviation?
Look at I & II - is either overall negative?
Yes = deviation
Is aVL more + or - ?
+ = L axis deviation, - = R axis deviation
What would you prescribe for pneumothorax?
Analgesia and O2
What does COPD look like on CXR?
Hyper-inflated lungs with flattened diaphragm
On CXR, what does reticular / nodular opacities indicate?
Pulmonary fibrosis
On CXR, what does airspace fluffy shadowing indicate?
Pneumonia
On CXR, what does interstitial shadowing indicate?
Infection
On CXR, what does homogenous white indicate?
Pleural effusion
On CXR, what does unilateral white out indicate?
Lung collapse
On CXR, what does airspace-fluid level indicate?
Cavitating lesion
