Oscillometry in Chronic Obstructive Lung Disease : In vitro and in vivo evaluation of the impulse oscillometry and tremoflo devices
Impedance, or oscillometry, measurements of the respiratory system can generate information about the function of the respiratory system not possible with traditional spirometry. There are currently several instruments on the market using different perturbations. We have compared a new respiratory oscillometry instrument, the tremoflo, with Impulse Oscillometry (IOS). Patients with a physician’s d
