This is a sample of our (approximately) 4 page long Asthma notes, which we sell as part of the Respiratory Notes collection, a MBChB (hons) (1st) package written at University Of Leicester in 2014 that contains (approximately) 35 pages of notes across 13 different documents.
The original file is a 'Word (Docx)' whilst this sample is a 'PDF' representation of said file. This means that the formatting here may have errors. The original document you'll receive on purchase should have more polished formatting.
The following is a plain text extract of the PDF sample above, taken from our Respiratory Notes. This text version has had its formatting removed so pay attention to its contents alone rather than its presentation. The version you download will have its original formatting intact and so will be much prettier to look at.
Asthma An inflammatory condition causing reversible airway obstruction Epidemiology
- 2000 deaths a year in UK
- Prevalence 10-15%
- Classified as o Extrinsic (childhood, associated with atopy, remits in teens) o Intrinsic (develops later in life, doesn't respond to rx well) o Occupational (relates to workplace allergen) Aetiology
- Genetic predisposition o Runs in families with atopy (eczema, hayfever, asthma, conjunctivitis)
- Environmental factors o Drugs (aspirin, B blockers) o Allergens (dust, pollen, animal hair) o Occupational (wood, dust, dye) o Environmental (cold air, exercise, emotion) Pathophysiology 3 factors contribute to airway narrowing 1) Bronchial muscle contraction + hypertrophy 2) Mucosal inflammation caused by mast cells + basophil degranulation, resulting in release of inflammatory cytokines 3) Increased mucus production Clinical features Symptoms (all INTERMITTENT) Dyspnoea Wheeze Nocturnal cough Sputum Diurnal variation of peak flow +
symptoms (worse in morning) Decreased exercise tolerance
Signs Tachpnoea Audible wheeze Hyperinflated chest Hyperresonant percussion note Decreased air entry Widespread, polyphonic wheeze
Assessing the severity of an asthma attack
- Moderate o PEFR 110bpm o Resp rate > 25 o Inability to complete sentences o Wheezy chest o Alert/mild confusion o Very low pO2, normal pCO2, normal pH
- Life threatening
