Lung function and bronchial responsiveness measured by forced oscillometry after bronchopulmonary dysplasia.
Forced oscillometry was used to investigate whether lung injury due to bronchopulmonary dysplasia in early life caused abnormalities in bronchial calibre or an increase in bronchial responsiveness to histamine at school age. Results were compared with data obtained from healthy children born prematurely and from healthy children born at term. There was a mild increase in frequency dependence of...
متن کاملBronchial responsiveness to histamine and methacholine measured with forced expirations and with the forced oscillation technique.
The objective of this study was to compare bronchial challenge tests with two substances [histamine (H) and methacholine (M)] and two methods of measuring the effect parameter FEV1 and pulmonary impedance [with the forced oscillation technique (FOT)] in order to determine which test is the shortest, and gives the least (drug) load to the patient. Furthermore, it was considered whether the resul...
متن کاملBronchial responsiveness after human heart-lung transplantation.
We evaluated bronchial responsiveness to inhaled albuterol (salbutamol), ipratropium bromide, methacholine, and propranolol in eight heart-lung transplant (HLT) recipients 2.3 +/- 1.5 months (mean +/- SD) (range, 1 to 4.5 months) after HLT. All patients had a restrictive ventilatory defect but none had airflow limitation (FEV1/FVC = 0.93 +/- 0.05) (range, 0.86 to 0.97). Specific airway conducta...

refinement. However, we remain committed to the continual refinement of explicit algorithms because they are the best means of achieving and sustaining long-term gains in performance. Implicit algorithms are the mental models an individual uses to select his or her response to a given situation. Although experience allows the individual to refine these models, that knowledge remains internal an...
متن کاملLongitudinal measures of lung function in infants with bronchopulmonary dysplasia.
We previously demonstrated that infants with a history of bronchopulmonary dysplasia (BPD) exhibit airflow obstruction and air trapping. The purpose of this study was to assess longitudinal changes in pulmonary function in infants with a history of BPD over the first 3 years of life, and the relationship to somatic growth. Spirometry was measured using the raised volume rapid thoracoabdominal c...
