Asthma 1 - classical features + occupational asthma Flashcards
? infl condition of the airways that is ? - characterised by airways ? to a number of factors
-it affects ? of children and ? of adults
chronic reversible hypersensitivity 10% 5%
Sx are variable but ?
- reversible ? resulting in airway ?
- > ? and SOB
- > classically worse during ? or in ? or upon exercise
- > ? ? worse in morning ‘morning dipping’
- > subjective feeling of chest ?
- ?, again classically nocturnal
recurring bronchospam obstruction wheezing night morning peak flow tightness cough
O/e - widespread ? ?
PFT - reveals ? FEV1 (peak flow) relieved by ? ?
expiratory wheeze
decreased
B2 agonists
Common precipitants
- env ?: pets, grass pollen, dust mites
- ? infections
- ? air
- emotion
- drugs: NSAIDs particularly ?, ? are CI’d
- atmospheric pollution
allergens viral cold aspirin BBs
Occupational pollutants eg ? or chemicals
- makes up ?% of adult asthma
- diagnosed how?
Many children will ? ? of their asthma
flour
10-15
serial peak flow every two hours and record where they are and what they are doing
Important Hx points: known ? ? variations in sx history of ? (also any family history) ? ? sx - known association occupation and days off work/school - how do sx change?
history of ?, and whether they needed admission/??? is important
precipitants diurnal atopy acid reflux exacerbations ITU
Dx -is a ? diagnosis - if Sx suggestive, perform assessment to see if:
- episodes are ?
- Sx are ?
- PH/FH of ?
- recorded observation of ?
- variable ??? or FEV1
- absence of sx of an alternative diagnosis
clinical recurrent variable atopy wheeze PEF
Dx
if high prob of asthma - diagnose as ? asthma and initiate treatment
-if this leads to an ? improvement of Sx (either shown by ? function or ? symptom score system), Dx can be confirmed
-if poor response to treatment, refer for ? to test for airway ? with ? reversibility -> FEV1/FVC less than ?%, with reversibility is diagnostic
-PEF ? can also be used to aid Dx
suspected objective lung validated spirometry obstruction bronchodilator 70% charting
