|Import Data to SpV|
It is recommended to use a BVF if the asma-1 is intended for multi-subject use. The plastic mouthpiece supplied with the device can be used where the device is intended for single-subject use. For subject groups with excessive sputum production, a BVF can be used to protect the device from exhaled particulate matter where this may be a concern.
The (!) appears after a blow if; Vext (extrapolated volume) is > 5% or 100mL of FEV6 or a cough is detected in the 1st second.
If a new BVF is used for every test subject and the device is stored in a clean, dust free environment, then the monitor should require only surface cleaning using a 70% isopropyl alcohol wipe. If you suspect that the device flow head has become contaminated, refer to the 4000 Series Cleaning Instructions.
