A multiple-breath washout technique was used to assess residual ventilation heterogeneity in the conductive and acinar lung zones of asthmatic patients after maximal beta(2)-agonist reversibility. Reversibility was assessed in 13 patients on two separate visits corresponding to a different baseline condition in terms of forced expiratory volume in 1 s [FEV(1); average FEV(1) over 2 visits: 92 +/- 21% of predicted (SE)]. On the visit corresponding to each patient's best baseline, 400 micro g…

Ventilation heterogeneity in asthma
TLDR
Current evidence strongly supports ventilation heterogeneity as a fundamental derangement of lung function in asthma that contributes per se to hypoxemia and airway hyper-responsiveness and response to corticosteroid dose titration.
Ventilation heterogeneity in children with well controlled asthma with normal spirometry indicates residual airways disease
TLDR
The presence of residual ventilation heterogeneity in children with well controlled asthma and normal FEV1 is identified and the role of LCI in measuring early airway disease inChildren with asthma requires further exploration.
Peripheral airway involvement in CF and asthma compared by inert gas washout
TLDR
Overall ventilation inhomogeneous and particularly inhomogeneity in or close to the gas exchange zone are more pronounced in CF than in asthma matched for FEV1, while inhom heterogeneity in the conducting airway zone is similar.
Ventilation Heterogeneity and Airway Hyperreactivity in Children with Well Controlled Asthma
TLDR
The relationship between ventilation heterogeneity and airway reactivity suggests that normalizing ventilation heterogeneity may be an important therapeutic target for treating children with asthma.
Peripheral lung function in patients with stable and unstable asthma.
Peripheral airway involvement in asthma assessed by single-breath SF6 and He washout
TLDR
Airways close to the acinar entrance participate in the overall airway response to cold-air challenge in asthmatic adults with marked airway hyperresponsiveness to cold, dry air.
Effects of cystic fibrosis lung disease on gas mixing indices derived from alveolar slope analysis
Volumetric capnography to detect ventilation inhomogeneity in children and adolescents with controlled persistent asthma.
TLDR
The increase in the slope of phase III normalized by tidal volume in asthma patients suggests that these patients have ventilation inhomogeneity in the distal air spaces, which may reflect chronic structural disorders or reversible acute changes seen on the bronchial provocation test.
Hyperpolarized 3He magnetic resonance imaging ventilation defects in asthma: relationship to airway mechanics
TLDR
In patients with asthma, magnetic resonance imaging provides direct measurements of regional ventilation heterogeneity, the etiology of which is not well‐understood, and impedance predictions were made using a computational airway tree model with simulated constriction of airways related to ventilation defects measured in mild‐moderate asthmatics.

Ventilation distribution during histamine provocation.
TLDR
The main findings of this study are that during provocation large ventilation inhomogeneities occur, that the small airways affected by the provocation process are situated proximal to the acinar zone where the diffusion front stands, and that, in addition to overall decrease in airway caliber, there is inhomogeneous narrowing of parallel airways.
Ventilation distribution and density dependence of expiratory flow in asthmatic children.
TLDR
Results indicate that steep SBO2 slopes found in asthmatic children between acute episodes reflect unequal time constants caused by obstruction of peripheral airways and part of the variation in DD among astHmatic children is caused by variation in convective accelerative pressure losses in major airways.
Respiratory impedance and multibreath N2 washout in healthy, asthmatic, and cystic fibrosis subjects.
TLDR
It is implied that significant nonuniform peripheral airway obstruction can exist such that ventilation distribution is abnormal but Zrs from 4 to 60 Hz is not, and that combining Zrs and the MBNW may permit us to infer whether the disease is predominantly in the lung periphery or in the more central airways.
Evidence of acinar airway involvement in asthma.
TLDR
This study primarily demonstrated significant, but partially reversible, acinar airway impairment in patients with asthma, as compared with the more severe baseline acinarAirway impairmentIn patients with COPD, which was not reversible after salbutamol inhalation.
Differences in airway closure between normal and asthmatic subjects measured with single-photon emission computed tomography and technegas.
TLDR
There is a predictable pattern of airway closure in normal subjects and that it is primarily influenced by pulmonary elastic recoil, probably secondary to allergic inflammation, but this pattern is lost in asthmatic subjects.
Effects of cool, dry air stimulation on peripheral lung mechanics in asthma.
TLDR
A stop-flow method to measure the decay of segment pressure with time that yielded information on airway resistance (Raw), final plateau pressure (Pp), and peripheral lung compliance (Cp) concluded that Rp is predominantly determined by the resistance of the collateral airways rather than the more proximal airways.
Airway and lung tissue mechanics in asthma. Effects of albuterol.
TLDR
In asthma, Raw comprises the majority (> 70%) of RL at breathing frequencies, and the relative contributions of Raw and Rti to RL appear to be independent of the degree of smooth muscle constriction.
Methacholine versus histamine: paradoxical response of spirometry and ventilation distribution.
TLDR
The observed ventilation heterogeneities predict a risk for dissociation between ventilation-perfusion mismatch and spirometry, particularly after methacholine challenge, probably at the level of the large and small conductive airways.
Ventilation inhomogeneity in oleic acid-induced pulmonary edema.
TLDR
The data show that, after oleic acid infusion, dcdi, which represents VI in peripheral airways, is responsible for the increasing total VI as lung water accumulates progressively over time, while the cdi remains relatively constant throughout.
Airway constriction pattern is a central component of asthma severity: the role of deep inspirations.
TLDR
It is conjecture that inflammation and wall-remodeling facilitate a dangerous degree of heterogeneous constriction inclusive of airway closures or near closures, and contribute to the prevention of a DI from having a residual bronchodilatory effect.
