spirometry
Pronunciation: spy-ROM-eh-tree
Pulmonary function test measuring lung volumes and airflow rates, requiring patient cooperation and typically performed in children over 6 years.
Full Definition
Spirometry is a standardized pulmonary function test that measures the volume and speed of air that can be inhaled and exhaled, providing objective assessment of lung function. In pediatric practice, spirometry requires patient cooperation and understanding, making it typically feasible for children 6 years and older. Key measurements include forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow rate (PEFR). The test helps diagnose and monitor respiratory conditions such as asthma, evaluate treatment response, and assess disease progression. Pre- and post-bronchodilator testing may be performed to evaluate reversible airway obstruction.
Usage
Usage note: Age limitations and cooperation requirements should be noted when ordering for pediatric patients.
