LungFunction

 A Spirometer is an essential diagnostic medical device used to measure how much and how quickly air can be inhaled and exhaled by the lungs. By performing forced breathing maneuvers, it generates key parameters—primarily Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1)—that are fundamental for diagnosing and monitoring obstructive and restrictive lung diseases like Asthma and COPD. Requiring daily calibration and strict adherence to international standards (ATS/ERS), it provides the objective, reproducible data needed for clinical decision-making in pulmonology, primary care, occupational health, and pre-operative assessment.
