Final answer:
Asthma PFTs (Pulmonary Function Tests) between attacks assess the lung function, while PFTs during attacks provide information about the severity and airway obstruction.
Step-by-step explanation:
Asthma PFTs (Pulmonary Function Tests) conducted between asthma attacks assess the lung function of an individual. These tests measure various parameters such as lung volume, air flow rate, and gas exchange to evaluate the overall health of the airways and lungs. Common PFTs performed between attacks include spirometry, which measures forced expiratory volume (FEV1) and forced vital capacity (FVC), and peak flow meter, which measures the maximum speed of exhaled air.
During an asthma attack, PFTs can provide information about the severity of the attack and the degree of airway obstruction. The results may show decreased lung volume, reduced airflow, and impaired gas exchange. Spirometry during an attack may reveal decreased FEV1 and FVC values. The objective is to monitor the lung function changes during an attack to guide treatment decisions and assess the effectiveness of interventions.
