Effect of bronchial challenge on breathing patterns and arterial oxygenation in stable asthma.
The effect of histamine or methacholine inhalational challenge on breathing patterns and oxygen saturation was investigated in ten stable asthmatic patients. We used the respiratory inductive plethysmograph to record respiratory timing and minute ventilation along with an ear oximeter to measure oxygen saturation (SaO2). As FEV1 fell during the challenge procedure, SaO2 also fell (average 3 per...
متن کاملHeterogeneity of bronchial endothelial cell permeability.
In vivo models of airway inflammation suggest that most protein transudation occurs from bronchial microcirculation. However, due to technical limitations in the isolation and culture of bronchial endothelial cells, most studies of lung vascular permeability have focused on pulmonary endothelium. Thus conditions for culture of sheep bronchial artery endothelial cells (BAEC) and bronchial microv...
متن کاملCircadian patterns of breathing
In the rat, a mostly nocturnal animal, activity, body temperature and metabolic rate increase during the dark hours of the day. Since all these variables are known to influence breathing, it is expected that also pulmonary ventilation (VE) will present a circadian pattern. In rats chronically instrumented for measurements of body temperature and activity by telemetry, carbon dioxide production ...
متن کاملSupport vector regression for prediction of gas reservoirs permeability
Reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. In fact, determination of permeability is a crucial task in reserve estimation, production and development. Traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. Well log data is an alternative approach for prediction of pe...
متن کاملBreathing pattern during bronchial challenge in humans.
Increases in minute ventilation (V'E) have been observed during exacerbations of asthma and in response to administration of histamine. However, it is not yet clear how the breathing pattern is affected, and whether the increase in V'E is found in general. In the present study, the effects of inhalation of histamine on respiratory frequency (fR), tidal volume (VT), V'E, and on functional residu...
