What are Spirometry Filter?
Filters used in pulmonary function laboratories are consumable items used for trapping bacteria and viruses, ensuring prevention of any cross-contamination. The filters generally consist of a flat wad of electrostatically charged fibres or pleats formed from a wad of fibres.
These filters may/should have hydrophobic properties.
Why use Spirometry Filters
- They are also designed to stop moisture droplets passing to and from the spirometer.
- Spirometry Filters protects both patient and spirometer from cross contamination
- Should be used when an inspiratory manoeuvre is performed or when testing patients who pose a health risk to others.
