Spirometry Asthma Values at Andrea Rumfelt blog

Spirometry Asthma Values. The key indices measured by a spirometer (figure 1) are forced vital capacity (fvc), forced expiratory volume in 1 second (fev1), peak. In patients with asthma, the global initiative for asthma uses an fev 1 /fvc ratio cutoff of less than 0.75 to 0.8 in adults and less than 0.9 in. When spirometry is carried out for the first time, the data is compared with predicted values. The fev1 /fvc ratio below the lower limits of normal is consistent with airflow obstruction. However, predicted values are not necessarily. The definitive diagnosis of asthma requires the history or presence of respiratory symptoms consistent with asthma, combined.
