EasyOne Air Spirometer for COPD & Respiratory Disease Management

Chronic Obstructive Pulmonary Disease) is diagnosed and staged using spirometry — specifically the FEV1/FVC ratio. The EasyOne Air provides the precision needed for COPD staging per GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria. It is also widely used for:

• Asthma - assessing bronchodilator reversibility 
• Pulmonary Fibrosis - detecting restrictive patterns via FVC decline
• Occupational Lung Disease - serial monitoring of at-risk workers
• Pre-operative Assessment - Surgical Risk Stratification

When used under a doctor's supervision, this spirometer is also recommended by many clinicians for home monitoring of COPD. However, clinical-grade testing in a professional environment remains the standard of care.
