Diseases Flashcards
Classify severe asthma
cannot complete sentences in one breath respiration rate >/or equal to 25 pulse >/or equal to 110 use of accessory muscles Peak flow less than 50% of predicted value/ best known value
How would you classify life-threatening asthma?
Peak expiratory flow less than 33% of predicted or best known
SpO2 less than 92%
Silent chest, cyanosis, feeble respiratory effort
Too dyspnoeic to speak
Bradycardia or hypotension
exhaustion, confusion,coma
What first line investigations would you do before treatment in severe asthma?
Peak expiratory flow
Oximetry
What immediate treatment would you do in severe or life-threatening asthma?
Oxygen
Salbutamol give via oxygen nebuliser
Prednisolone tablets
What other investigations would you consider in acute severe asthma?
Chest X-Ray (to exclude pneumothorax or consolidation)
U and E
FBC
Define mild asthma?
Dyspnoea only with exertion
Peak expiratory flow rate (PEFR) >70% of predicted or personal best
Oxygen saturation >95%
Prompt relief with inhaled short-acting beta-2 agonist
Define moderate asthma?
Dyspnoea limits usual daily activity
PEFR 40% to 69% of predicted or personal best
Oxygen saturation 91% to 95%
Relief from frequent inhaled short-acting beta-2 agonist
Some symptoms last for 1 to 2 days after treatment is started
How to you treat mild intermittent asthma?
short acting beta agonist
Define mild persistent asthma?
Symptoms >2 times a week but <1 time a day Exacerbations may affect activity Night-time symptoms >2 times a month FEV1 ≥80% of predicted PEFR variability between 20% and 30%
How do you treat moderate persistent asthma?
low dose inhaled corticosteroids and LABA and SABA
OR medium dose inhaled corticosteroid and SABA
Define moderate persistent asthma
Daily symptoms
Use of short-acting beta agonists daily
Attacks affect activity
Exacerbations ≥2 times a week and may last for days
Night-time symptoms >1 time a week
FEV1 greater than 60% to <80% of predicted
PEFR variability >30%
How do you treat moderate persistent asthma?
low dose inhaled corticosteroids and LABA and SABA
OR medium dose inhaled corticosteroid and SABA
Define severe persistent asthma?
Continual symptoms Limited physical activity Frequent exacerbations Frequent night-time symptoms FEV1 ≤60% of predicted PEFR variability >60%.
How do you treat severe persistent asthma?
medium dose inhaled corticosteroids and LABA and SABA
Define mild intermittent asthma
Symptoms ≤2 times a week
Asymptomatic and normal peak expiratory flow rate (PEFR) between attacks
Attacks are brief with varying intensity
Night-time symptoms ≤2 times a month
Forced expiratory flow at 1 second (FEV1) or PEFR ≥80% of predicted
PEFR variability <20%
