    Study Notes

    Understanding Asthma: Symptoms, Triggers, Diagnosis, and Family History

    • Key symptoms of asthma are cough, wheeze, breathlessness, and tightness across the chest
    • Children with asthma may present with a history of cough on exercise or at night, while adults may experience tiredness and heaviness in the chest
    • Common triggers of asthma include viral or bacterial infections, allergens, physical activity, stress, and certain drugs
    • Patients with asthma, particularly children, may have a history of recurrent upper and lower respiratory tract infections and allergies
    • Family history plays a role in asthma, and children of mothers who smoked while pregnant are more likely to develop asthma
    • Physical examination may not detect abnormalities, but it can help exclude other possible causes like chest infection or heart failure
    • Lung function tests, such as peak expiratory flow (PEF) and spirometry, are crucial for confirming the diagnosis of asthma
    • PEF is a simple, quick, and inexpensive lung-function test that measures the maximum rate of air forcibly exhaled
    • Spirometry provides more detailed information about the condition of the airways than PEF, measuring forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC ratio
    • A measured PEF less than 80% of predicted indicates airway obstruction, potentially due to asthma, but a diagnosis of asthma requires variability of 15% or more between two readings on separate occasions
    • Spirometry measures such as FVC, FEV1, and FEV1/FVC ratio are compared with predicted values and abnormal results can indicate disease or airway obstruction
    • Proper diagnosis of asthma involves comprehensive understanding of symptoms, triggers, family history, and accurate lung function tests.
