Lung clearance index: should we really go back to nitrogen washout?
We (Innovision ApS, Odense, Denmark) are the manufacturer of the AMIS 2000 medical mass spectrometer system that, using user-specific software and hardware, was adapted to perform MBW. The AMIS 2000-based devices are now considered the ‘‘gold standard’’ device for SF6 LCI measurements in cystic fibrosis patients by opinion leaders in the field [2]. This device has been used in the vast majority...
متن کاملNitrogen washout/washin, helium dilution, and computed tomography in the assessment of end-expiratory lung volume
INTRODUCTION End expiratory lung volume (EELV) measurement in the clinical setting is routinely performed using the helium dilution technique. A ventilator that implements a simplified version of the nitrogen washout/washin technique is now available. We compared the EELV measured by spiral computed tomography (CT) taken as gold standard with the lung volume measured with the modified nitrogen ...

متن کاملCorrection: Nitrogen washout/washin, helium dilution and computed tomography in the assessment of end expiratory lung volume
Comparison of end expiratory lung volume (EELV) measured by the helium dilution technique and the nitrogen washout/ washin method. (a) The EELV measured by the helium dilution as a function of the EELV measured by nitrogen washout/washin method (EELV helium dilution = -111.85 + 0.89 × EELV GE, r2 = 0.82, p < 0.00001). (b) The BlandAltman plot of the EELV measured with the nitrogen washout/washi...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
