Spirometry Test: How It Works and Why It Matters for Lung Health #208940 (License: Personal Use)

The image shows a side-profile illustration of a person actively exhaling into a handheld spirometer via a flexible tube, while the device’s console displays digital readouts and control indicators. The setup reflects standard clinical spirometry used to evaluate forced expiratory volume (FEV1) and forced vital capacity (FVC). This diagnostic procedure is essential for monitoring chronic respiratory diseases and assessing preoperative pulmonary risk.

Used on medical websites, patient education portals, or pulmonology clinic pages to illustrate how spirometry is performed; matches user intent for understanding respiratory testing, preparing for a doctor’s visit, or researching lung health diagnostics.
