Variation between observers in the estimation of airway resistance and thoracic gas volume.

Separation of airway and tissue properties by transfer respiratory impedance and thoracic gas volume in reversible airway obstruction.

The aim of this study was to establish the ability to estimate separate airway and tissue properties from transfer respiratory impedance (Zrs,tr) data in the presence of airway obstruction. Zrs,tr, thoracic gas volume (TGV) and airway resistance (Raw,pleth) were measured in the presence of obstruction and after use of a bronchodilator (BD) in 13 normal or asymptomatic asthmatic adults and 28 ch...

Overestimation of thoracic gas volume during the airway resistance maneuver. A potential error in the diagnosis of air trapping.

There are no data published about the agreement between the measurement of thoracic gas volume (TGV) during the airway resistance (TGV-Raw) and the conventional technique described by Dubois. The aim of this study was to establish the agreement between both methods to measure TGV. We studied eighty consecutive subjects. Only sixty-six performed acceptable plethysmography maneuvers. The patients...

Thoracic gas volume at functional residual capacity measured with an integrated-flow plethysmograph in infants and young children.

Thoracic gas volume (TGV) was measured with an integrated flow plethysmograph in 15 infants aged 2-34 months. End-expiratory (TGVe) and end-inspiratory (TGVi) airway occlusions were compared, after correction of TGV for the occluded volume above functional residual capacity (FRC). The relationship between pressure at the airway opening (Pao) and volume displaced from the box during airway occlu...

International Congress of Airway & Interstitial Lung Diseases (ICAILD 2018)

“International Congress of Airway & Interstitial Lung Diseases” took place on November 14-16, 2018, in Pardisan Hotel,Mashhad,Iran. Hosted in our home city of Mashhad, the second largest city, in the North East of Iran. It is famous for the holy shrine of Imam Reza as well as Toos,the residence of Ferdowsi, the great Persian poet. The congress scientific program presented the best in science an...
