South and Central America Forced Oscillometry Market Outlook

The integration of forced oscillometry with artificial intelligence, digital health platforms, and telehealth is revolutionizing respiratory care by enabling precise, continuous, and patient-centered lung function monitoring beyond traditional clinic settings. AI and machine learning algorithms process oscillometry parameters—such as respiratory resistance (R5, R20), reactance (X5), and frequency dependence—to build predictive models that classify respiratory conditions with high accuracy. For example, neural network classifiers trained on oscillometry system profiles can reliably distinguish healthy individuals from those with asthma or COPD, while also flagging early small airway changes that spirometry misses. A PMC study developed an ML model using IOS profiles to categorize patients into no obstruction, asthma, or COPD, achieving an overall accuracy of 0.786 with a neural network classifier, where R5-R20 emerged as key features for differentiation. In distinguishing between COPD and asthma, the model achieved 0.854 accuracy. Cureus validated AI in oscillometry for asthma, detecting resistance and reactance accurately. For early COPD detection, BREATH Hannover's AI-combined oscillometry identified small airway dysfunction in 40% of screened individuals, flagging a high-risk group for comorbidities. Researchers are exploring AI-driven predictive analytics in FOT for post-surgical lung function recovery, where algorithms forecast complications based on preoperative impedance profiles.

Portable oscillometry devices, paired with user-friendly mobile apps, allow patients to perform effortless tidal-breathing tests at home; the data are automatically transmitted to secure cloud platforms for real-time clinician review. This connectivity supports telehealth consultations in which physicians analyze trends alongside patient-reported symptoms, promptly adjusting therapies for chronic conditions such as asthma or post-COVID respiratory issues. Digital dashboards empower patients by visualizing their airway mechanics, improving adherence, and self-management. By combining the effort-independent nature of oscillometry with AI-driven insights and remote connectivity, this trend is making advanced lung function assessment accessible to underserved populations, reducing unnecessary hospital visits, and enabling proactive, personalized interventions in everyday respiratory care.

South and Central America Forced Oscillometry Market Country Insights

By country, the South and Central America Forced Oscillometry Market is segmented into Brazil, Argentina, and the Rest of South and Central America. Brazil held the largest share in 2025.

Brazil faces a significant burden of respiratory diseases, where forced oscillometry is utilized as a noninvasive tool for assessing lung function, particularly in patients with asthma and COPD. According to the Brazilian Ministry of Health, the prevalence of asthma among adults was ~9.1% in 2022, based on the National Health Survey (PNS) data, reflecting persistent airway inflammation and small airway dysfunction across urban and rural populations. In 2023, the Ministry reported that respiratory diseases continued to be a leading cause of outpatient visits, with over 1.2 million consultations attributed to chronic conditions. In 2024, data from the Brazilian Unified Health System (SUS) indicated high respiratory morbidity, with asthma and COPD driving emergency department utilization.

The National Health Surveillance Agency (ANVISA) approved portable oscillometry devices in 2023-2024 under the Medical Devices Regulation, increasing accessibility for patients unable to perform conventional spirometry. ANVISA's 2023 asthma and COPD management guidelines also emphasized the use of FOT for early detection of small airway changes and monitoring treatment response. Recent developments in FOT include its application in evaluating small airway disease in occupational asthma, where a 2024 study from the University of Sao Paulo showed increased respiratory resistance and reduced compliance in affected workers, aiding early diagnosis. Another 2023 pilot study at a Sao Paulo hospital demonstrated FOT's feasibility in monitoring cystic fibrosis exacerbations, revealing improved reactance post-treatment without requiring patient effort. In silicosis, FOT has been validated for grading airway obstruction, as per a study updated in 2022 guidelines from the Brazilian Thoracic Society, enhancing detection in high-risk mining populations. Additionally, FOT assessments in idiopathic scoliosis patients, per a 2023 Brazilian Journal of Medical and Biological Research publication, identified elevated resistance at multiple frequencies, supporting its role in preoperative evaluations. These advancements highlight FOT's growing integration into Brazil's public health system for better respiratory management, especially in underserved areas.
