FAQs
Do I need a 3L syringe to perform a calibration verification on my spirometer every day?
AddThe 2019 ATS/ERS 2019 Technical Standards recommend:
“Calibration verifications must be undertaken at least daily using a 3-L syringe cycled at least three times to give a range of flows varying between 0.5 and 12 L/s (with 3-L injection times between 0.5 and 6 s). If an in-line filter is used in spirometry testing, then it must also be used during recalibrations and verifications.”
Do I need a 3L syringe if I perform a Biological Control procedure every day?
AddYes. The 2019 ATS/ERS 2019 Technical Standards recommend:
“A biological control is not a substitute for the use of a calibration syringe. However, operators are encouraged to know their own usual FEV1 and FVC, which allows them to conduct a quick, rough check if they suspect a problem.”
