Pneumonia TCD Flashcards
Which patients with respiratory infection should be referred to hospital for treatment?
The patients who have suspected pneumonia and need further investigations / interventions. Usually they will have signs of severe respiratory infection (high fever, or low blood pressure/ high respiratory rate / with confusion). Also if it is felt that the patient would not be able to manage at home.
CAP could be defined simply as…
‘Signs of lower respiratory tract infection (fever/cough/phlegm/crepitations or bronchial breathing) + CXR changes.’
How do you assess CAP severity and treatment?
CURB65 score, 1 mild, 2 moderate, 3 severe
Which patients does CURB65 not work well in?
Patietns younger than 65 as they will not score highly even if ill, and they compensate. Patients with bad renal function so high urea when well.
What six domains is NEWS2 based on?
respiration rate oxygen saturation systolic blood pressure pulse rate level of consciousness or new confusion* temperature

Bronchiectasis
Structural damage of airway where there is both narrowing and dilatation - Large volume of sputum production. the wide parts are constantly colonised. DIAGNOSE VIA CT normally H. Influenzea. Sample sputum regularly as this will help when exacerbation
