Final answer:
To assess airflow limitation, spirometry or a nebulizer can be used. Symptoms and risk of exacerbations in asthma can be evaluated by considering factors such as airway irritation, dyspnea, cough, chest tightness, wheezing, and bronchospasm.
Step-by-step explanation:
To assess airflow limitation, spirometry can be used. Spirometry measures the amount of air a person can forcefully exhale in one second (FEV1) and the total amount of air they can exhale (FVC). The ratio of FEV1 to FVC can be used to diagnose obstructive lung disease if it is lower than 69%, indicating airway obstruction. Alternatively, a nebulizer can be used to detect the rate at which air can be expelled from the lung.
To assess symptoms and the risk of exacerbations in asthma, several factors can be considered. These include airway irritation, dyspnea (shortness of breath), cough, chest tightness, wheezing, and bronchospasm. The presence and severity of these symptoms can help healthcare professionals evaluate the symptoms and determine the risk of exacerbations. It's important for individuals with asthma to regularly monitor their symptoms and report any changes to their healthcare provider.
