mbw sulfur hexafluoride Network Monitor pricing

Multiple-breath washout (MBW) has been shown to detect early impairment of lung function in children with cystic fibrosis (CF). Nitrogen (N2) or sulfur hexafluoride (SF6) can be used as tracer gas for MBW. Recent data indicated higher lung clearance index (LCI) values measured with N2-MBW than concurrent SF6-MBW in older children and adults, however, a comparison in infants and younger ...

  • Multiple Breath Washout (MBW) Using Sulfur Hexafluoride

    Multiple breath washout (MBW) using Sulphur hexafluoride (SF6) has the potential to reveal ventilation heterogeneity in obstructive lung disease which is frequent in patients with small airway disease. However, it is missed by commonly used tests with reference data being scarce and mostly restricted to younger collectives.
