This study sought to establish how often circadian airflow measurements (Peak Expiratory Flow rate or PEF) and how many values were needed for asthma management. That is the primary aim was not only to investigate circadian airflow variability but also airflow variability among three blows done ...
There was a significant correlation between peak-flow variability and mattress dust Der p I content in asthmatic children sensitized to dust mites, but not between peak-flow variability and classroom floor dust Der p I content. We concluded that carpeted classroom floors do not contribute to ...
VALIDITY OF PEAK EXPIRATORY FLOW-RATE VARIABILITY FOR THE DIAGNOSIS OF ASTHMA - AUTHORS REPLY 来自 clinsci.org 喜欢 0 阅读量: 25 作者: A Neuro 摘要: 1. Acute hypoxic pulmonary vasoconstriction is important in the restoration of ventilation-perfusion balance in the presence of regional alveolar ...
Despite the promising early results regarding its utility in the diagnosis and monitoring of childhood asthma, high variability in the sampling and analytical methods of EBC has precluded its widespread clinical application. To address this, the European Respiratory Society (ERS) recently provided ...
This variability in asthma diagnosis, with opportunity for remission and relapse, is further supported by the fact that 22 participants in whom current asthma was ruled out subsequently had a positive bronchial challenge test result during 1 year of follow-up. This study also suggests that ...
BACKGROUND: The variability of peak expiratory flow (PEF) is now commonly used in the diagnosis and management of asthma. It is essential for PEF meters to... MR Miller,SA Dickinson,DJ Hitchings - 《Thorax》 被引量: 297发表: 1992年 Patients' Perceptions Compared with Objective Ratings of ...
FRC and RV may be increased because of over-inflation of the lungs. Recovery is associated with a reduction in these lung volumes. Recordings of the peak expiratory flow rate (PEFR) for a week at home will often make the diagnosis of asthma obvious (Prior and Cochrane 1980). PEFR dips in...
Assess the patient’s peak flow. Assess the level ofoxygen saturationthrough the pulse oximeter. Monitor the patient’s vital signs. Nursing Diagnosis Based on the data gathered, thenursing diagnosesappropriate for the patient with asthma include: ...
The diagnosis of asthma was established by either a 15% diurnal variability in peak expiratory flow (PEF) or a > 15% bronchodilation to inhaled salbutamol. Patients were randomised to one of the following drug classes: a short-acting ß2-agonist (n = 21); an inhaled steroid (n = 25)...
Measurement of lung function is important, for diagnosis, evaluation of the reversibility, the variability and the severity of bronchial obstruction. Indeed, patient with asthma may have a poor recognition of their symptoms and a poor perception of bronchial obstruction. Peak expiratory flow meter is...
