2010 – Spirometric readings as an early warning marker for asthma
This study looks at the relationship between upper and lower airway conditioning in children diagnosed with moderate to severe mite-related rhinitis. By taking two spirometric readings, one at 25% and then 75% (FEF25%-75% ) the clinical team demonstrated that a simple reading of pulmonary volume can be an early warning marker for asthma. The study highlights the close link between the upper and lower airways and the role of some risk factors such as sensitization to mites in children. The article notes previous studies have confirmed this risk assessment for adults.
