Acute respiratory Flashcards
Using which system is PE risk calculated?
Well’s criteria
How is Well’s score used in acute SOB patients?
If >4 a PE is likely: admit and do immediate CTPA
If <4 it is less likely: perform a D-DIMER and only do CTPA if this is pos
What might an ECG show in PE?
Right axis deviation, RBBB
Recall 2 things that may be seen on CXR in PE
Pleural effusion
Elevation of hemidiaphragm
Differentiate the management of PE depending on whether the patient is haemodynamically stable or not
Stable: LMWH or fondaparinux until INR>2, warfarin
Unstable: alteplase to thrombolyse
How does the chest sound on auscultation in the case of pneumothorax?
Hyperresonant
What is the key size of pneumothorax above which there must be medical intervention?
2cm
When is it appropriate to aspirate a pneumothorax rather than drain it?
Primary pneumothorax >2cm when pt is <50 yrs
1-2cm pneumothorax when it is a secondary pneumothorax/ pt is >50
What should be done to manage larger pneumothoraces?
intercostal drain
What would make a pneumothorax an emergency?
If it were a tension pneuothorax
What is a tension pneumothorax?
Build up of air in the pleural space due to a one-way valve
Recall how a tension pneumothorax appears on examination
Reduced breath sounds
Tachycardia and tachypnoea
Deviation of trachea and displacement of apex beat (as mediastinum pushed out of place)
What is the immediate treatment required in tension pneumothorax?
Immediate needle decompression using wide boar needle in 2nd ICS at MCL
Define pneumonia
Inflammation of the alveoli caused by an infective pathogen
Results in air sacs filling with fluid/ pus
What is the most common community acquired cause of pneumonia?
Streptococcus pneumoniae
