The forced oscillation technique (FOT) is a noninvasive method with which to measure
respiratory mechanics. FOT employs small-amplitude pressure oscillations superimposed on the …

… If this difference is considered as representative of chest wall and lung flow resistance, this
value was lower than the previous estimate of 0.5 cm H 2 O·s·L -1 for chest wall resistance in …

… components (H/L) (20). The time course of the H/L ratio was then analyzed; this ratio was
computed over 10 inspirations at the end of each trial and was expressed as a fraction of the H/…

Breathing through an endotracheal tube and a demand valve may increase the work
performed by the respiratory muscles. Inspiratory pressure support (PS) is known to reduce this …

Background Pressure-controlled (PCV) and pressure-controlled inverse ratio ventilation (PCIRV)
have been proposed instead of volume-controlled conventional ratio ventilation (VC) …

The forced oscillation technique (FOT) is particularly attractive in a pediatric setting as it
requires only passive cooperation from the child. We assessed the sensitivity and specificity of …

The feasibility of spirometry or respiratory impedance measurements for assessing lung
function in the elderly was compared in 208 institutionalized patients with various degrees of …

… The compliance of both chambers was set at 82 mllcm H,O. PEEP was applied to the
driving chamber at a levelthat ensured synchronism of motions of the two chambers at onset of …

… From a group of 40 healthy nonsmokers (25 male, 15 female) studied with the FOT, we
derived the following equation: Grs=(0.638-H)+(0.004·A)–0.787, SEE=0.07, where H is the height …

We compared the efficacy of three devices delivering assisted non-invasive ventilation with
different working mechanisms, during room air breathing and during CO2-induced …
