1. The oscillation method for measuring total respiratory resistance (Rrs) is a simple method of assessing airway dimensions which can be applied in epidemiological surveys and potentially might be useful for detecting mild airway disease in smokers. However, it is not known whether abnormalities in Rrs are only present when there are also abnormalities in simple spirometric tests. 2. We have c...
The aim of the study was to determine whether the bronchomotor effect of a deep inhalation (DI) may be detected during tidal breathing in asthmatic children with spontaneous airway obstruction (AO). Two groups of children aged 5-15 yrs were studied. AO was mild in group 1 (n=12, forced expiratory volume in one second (FEV1) > or = 75% predicted) and moderate-to-severe in group 2 (n=9, FEV1 > or...
STUDY OBJECTIVE To determine the bronchodilator effect of recombinant human B-type natriuretic peptide (BNP; nesiritide) on patients with asthma. DESIGN A prospective, open-label study. SETTING Outpatient setting. PATIENTS Eight adult patients with asthma confirmed by > 12% and > 200 mL increase in FEV1 after bronchodilator inhalation. INTERVENTIONS An IV nesiritide bolus, 2 microg/kg, ...
