Forced Oscillometry Market Size and Forecast (2021 - 2034), Global and Regional Share, Trend, and Growth Opportunity Analysis Report Coverage: By Product (Device and Accessories), Application (Asthma, COPD, and Other Applications), End User (Hospitals and

The forced oscillometry market size is expected to grow from US$ 62.07 million in 2025 to US$ 98.60 million by 2034; it is projected to register a CAGR of 5.4% during 2026–2034. The rising prevalence of respiratory diseases, the effort-independent testing advantage, and technological advancements in devices are noteworthy factors contributing to the expansion of the forced oscillometry market size. Additionally, growing clinical emphasis on small airway dysfunction detection and the rise of hybrid oscillometry systems are projected to bring new forced oscillometry market trends in the near future.

Modern hybrid devices that use impulse oscillometry (IOS) or the forced oscillation technique (FOT) together with standard spirometry in a single device currently offer the best option for comprehensive respiratory testing. The systems provide impedance data, including resistance and reactance measurements at different frequencies, along with complete flow-volume data from a simple tidal-breathing test lasting 15-30 seconds. The system enables clinicians to assess central and peripheral airway function, detect small-airway dysfunction, evaluate bronchodilator response, and obtain standard spirometric indices without requiring patients to perform demanding activities that many cannot perform successfully. The fusion of these elements creates a highly efficient clinical operation process. The hybrid method enhances diagnostic precision by enabling the detection of minor peripheral airway alterations that spirometry fails to identify, while delivering FEV1 and FVC results alongside flow-volume curves that physicians and payers demand. The equipment at pulmonary function laboratories currently combines FOT oscillometry with complete spirometry to provide an instant assessment of bronchodilator response, enhancing diagnostic certainty for conditions such as asthmatic cough and preserved-ratio impaired spirometry. The Vyntus IOS platform from Vyaire Medical demonstrates its ability to conduct forced and slow spirometry tests, along with complete IOS resistance and reactance measurements, in a single device, including a lung-model visualisation feature that displays central and peripheral obstruction patterns. Thus, as adoption grows, these hybrid platforms are redefining forced oscillometry from a complementary technique into a core, all-in-one pulmonary function testing solution that enhances patient comfort, clinical efficiency, and diagnostic confidence across the entire spectrum of respiratory care, thereby emerging as a significant trend in the forced oscillometry market.

Product-Based Insights

Based on product, the forced oscillometry market is segmented into device and accessories. The device segment held the largest forced oscillometry market share in 2025. The segment is expanding because respiratory disorders, including asthma, COPD, and other lung conditions, require doctors to use precise, non-invasive diagnostic tools. Healthcare professionals and patients have become more aware of lung function monitoring, which has increased their need for oscillometry devices. Clinics, hospitals, and home care settings have adopted the devices because of their technological advancements, which enable users to operate portable devices that provide high accuracy. The growth of these devices has increased because healthcare providers need to monitor patients remotely and use telehealth services, thereby fueling the forced oscillometry market growth.
