Pulmonary function valve

Pulmonary function valves are reusable devices designed to regulate airflow during respiratory testing. They connect to diagnostic equipment to control the direction of inhaled and exhaled gases, ensuring accurate measurement of lung function metrics like airflow resistance and lung volume.

These valves are typically classified as medical devices and may require compliance with general safety and performance standards. They are often supplied as part of a larger pulmonary function testing system, rather than standalone products, and are used in clinical, research, or home settings for assessing lung health.
