To meet the needs of different users, we provide calibrated and standard versions of the QuickLung and QuickLung Jr. For training applications, calibration is not necessary and even for testing applications, calibration is not always required.
However, if you are performing formal testing and validation, you may need a calibration certificate to show measurement traceability. The requirements for quality protocols related to calibration and accuracy typically come from your organization or from the manufacturer of the device under test.
QuickLung calibration is conducted using an ASL 5000 Breathing Simulator which has traceability to the National Institute of Standards and Technology (NIST) via A2LA showing the “unbroken chain” of traceability to the International System of Units (SI). The Calibrated QuickLung includes a calibration certificate with a stated level of accuracy for both resistance and compliance settings while the standard QuickLung does not include such a certificate. That stated accuracy for the Calibrated QuickLung is +/- 10% for Compliance and +/- 20% for Resistance. We recommend recalibration on a yearly basis.
The standard QuickLung accuracy is approximately +/- 20% for compliance, and for this configuration, the accuracy of the resistance is not validated or specified.
Please note that the standard QuickLung cannot be calibrated after purchase. This is because the resistance orifices are calibrated before assembly of the QuickLung. Once it is assembled, we cannot do the testing required for calibration.
