resp stuff Flashcards
what is chronic bronchitis
long term symptoms of a cough and sputum production due to inflammation in the bronchi
what is emphysema
damage and dilatation of the alveolar sacs and alveoli, decreasing the surface area for gas exchange
investigations for COPD
-post bronchodilator spirometry (less than 70%)
-chest x-ray
first line investigations for asthma in adults
eosinophil count OR fractional nitric oxide
severe COPD
FEV1 30-49%
mild COPD
FEV1 > 80%
moderate COPD
50-79%
very severe COPD
< 30%
moderate asthma attack
-PEFR 50-75%
-speech normal
-RR < 25
-pulse < 110
severe asthma attack
-PEFR 33-50%
-can’t complete sentences
-RR > 25
-pulse >110
life threatening
-PEFR < 33%
-oxygen sats < 92%
-normal pCO2
-silent chest, cyanosis or feeble resp effort
-bradycardia, dysrhythmia or hypotension
-exhaustion, confusion or coma
indication for surgery in bronchiectasis
localised disease
whats the threshold for a Wells PE score to get a CTPA
4 or more
what investigation if wells score is less than 4
D-dimer
dry cough and erythema multiform?
MYCOPLASMA pneumonia
- can present in young people
within what time frame can you do a d-dimer
4 hours
if you suspect a PE, then CTPA is negative, what is the next step
do a proximal leg vein USS
PE + hypotension treatment
thrombolysis (they have haemodynamic instability!!!)
minimal symptom pneumothorax treatment
conservative treatment regardless of size
what does reduces transfer factor mean (TLCO)
impaired gas exchange
investigation for legionella pneumonia
urinary antigen test
most common cause of occupational asthma (chemical)
isocyanates
