Forced Oscillation Technique vs Impulse Oscillometry: Which Is Better for Modern Clinics?
As respiratory diseases like asthma, COPD, and post-COVID complications continue to rise, clinics are moving beyond traditional spirometry toward more advanced diagnostic methods. Two commonly discussed technologies are Forced Oscillation Technique (FOT) and Impulse Oscillometry (IOS) . Both methods measure airway resistance during normal breathing, but when it comes to choosing the right respiratory diagnostic device for clinics , understanding their differences is essential. This guide breaks down FOT vs IOS and helps clinics decide which solution fits modern clinical needs. What is Forced Oscillation Technique (FOT)? Forced Oscillation Technique (FOT) is an advanced method that measures lung function by applying external oscillatory signals during normal tidal breathing. Key benefits of FOT: No forced breathing required Detects small airway dysfunction early Provides resistance and reactance data Suitable for pediatric and elderly patients Modern systems like t...
