What instrument is used to measure lung volumes during breathing?

Correct option is C

The correct answer is (C) Spirometer
Explanation:
• A Spirometer measures lung volumes and capacities such as tidal volume, vital capacity, FEV1 and FVC.
• Used to diagnose asthma, COPD, restrictive lung diseases, and other respiratory disorders.
• Forms part of Pulmonary Function Tests (PFTs) recommended by the Ministry of Health and Family Welfare (MoHFW).
Information Booster:
• Spirometry generates a Flow-Volume Loop that helps identify lung abnormalities.
• FEV1/FVC ratio is crucial for differentiating obstructive and restrictive conditions.
Additional Knowledge:
• Respirometer: measures breathing rate.
• Sphygmomanometer: measures blood pressure.
• Pulse Oximeter: measures blood oxygen saturation.
• ABG Test: evaluates oxygen and carbon dioxide levels in blood.
