VBMax Pulmonary Function Testing Filter
VBMax™ Pulmonary Function Test filters are available in two styles: the VBMax e-Series with an integrated elliptical mouthpiece and VBMax Standard with a round patient-side port.
The VBMax e-Series PFT filters eliminate the need for a separate mouthpiece, but it may be used with a bite-block style disposable rubber mouthpiece. They are available in 30 mm, 31 mm, 35 mm and 36 mm port sizes.
VBMax Standard PFT filters may be used with a paper mouthpiece or a disposable rubber mouthpiece and are available in 30 mm, 31 mm, 33 mm, 35 mm, 36 mm and 48 mm port sizes to fit a variety of spirometers, including Cybermedic, SensorMedics, Creative Biomedics, MIR, Cosmed, Vitalograph, Jaeger and Medical Graphics (MGC Diagnostics). VBMax™ filters are CE marked.
Protect your patient and your testing instruments with the VBMax™ Pulmonary Function Filter. VBMax™ provides a high degree of protection for the patient as well as your testing equipment, while its low resistance allows for accurate testing results.
Independent laboratory tests have verified that this pulmonary function filter is highly effective. VBMax™ consistently filters out more than 99.999% of bacteria and 99.99% of viruses. At the same time, VBMax™ easily surpasses published ATS recommendations for flow resistance in pulmonary function instrumentation, which suggest resistance should be below 1.5 cm H2O/L/sec at flow rates of 14 L/sec.
