Corticosteroid Resistance in Airway Disease
Proceedings of the American Thoracic Society, 2004Resistance to the antiinflammatory effects of corticosteroids is very uncommon in asthma but common in chronic obstructive pulmonary disease. Recent understanding of the molecular mechanisms involved in the antiinflammatory actions of corticosteroids has revealed that there are several possible mechanisms for corticosteroid resistance.

Nasal airway inspiratory resistance.
The American review of respiratory disease, 1979The relationship between transnasal pressure and nasal flow is markedly curvilinear during tidal breathing in man, and there is poor agreement among the results of various methods used to define this characteristic with a single number. We used Rohrer's equation (P = K1 V + K2 V2), where P = pressure and V = flow, and calculated values for K1 and K2 ...

Effect of a previous deep inspiration on airway resistance in man.
Journal of applied physiology, 1961We measured airway resistance and thoracic gas volume by the body plethysmograph technique, and transpulmonary pressure in seven healthy, adult subjects, before and after induction of bronchoconstriction.

Plethysmographic measurements of specific airway resistance in young children.
Chest, 2005Validated methods for lung function measurements in young children are lacking. Plethysmographic measurement of specific airway resistance (sRaw) provides such a method applicable from 2 years of age.

Volume History Response of Airway Resistance
1995Airways exhibit pressure volume hysteresis. The degree of airway hysteresis is directly proportional to smooth muscle tone. The lung parenchyma also exhibits similar pressure volume hysteresis. The effect on airway size depends on the relative difference between parenchymal and airway hysteresis as demonstrated by Froeb and Mead [1].

Airflow resistance in lower airway of the dog
Journal of Applied Physiology, 1962The resistance of the lower airway was measured in dogs by an adaptation of the esophageal-balloon method. In normal dogs resistance was found to be lower than previously reported values and not appreciably changed by flow or volume. In dogs with increased resistance, induced either acutely by pilocarpine inhalation or chronically by repeated exposure
