Bronchial hyperresponsiveness - Wikipedia
Bronchial hyperresponsiveness (or other combinations with airway or hyperreactivity, BH used as a general abbreviation) [1] is a state characterised by easily triggered bronchospasm (contraction of the bronchioles or small airways).
Bronchial hyperresponsiveness
Bronchial hyperresponsiveness (BHR) is often regarded as a ‘hallmark’ of asthma and bronchoprovocation testing is frequently performed to support a diagnosis of asthma. …

2003年6月25日 · Bronchial hyperresponsiveness (BHR) is defined as excessive bronchial narrowing and manifests itself as an exaggerated bronchoconstrictor response of the airways to various inhaled stimuli (1).
Bronchial hyperresponsiveness - PubMed
Background: Bronchial hyperresponsiveness (BHR) is often regarded as a 'hallmark' of asthma and bronchoprovocation testing is frequently performed to support a diagnosis of asthma. However, BHR is also found in a spectrum of other lung diseases and can be provoked by a variety of specific stimuli.
Mechanisms of Airway Hyperresponsiveness in Asthma: The Past, Present ...
Airway hyperresponsiveness is characterised by both an increased sensitivity, seen as the leftward shift in the DRC of the asthmatic patient (A), and excessive bronchoconstriction, resulting in the loss/increase in the maximal response plateau (B). But let’s start with a pair of case studies.
Bronchial provocation tests in clinical practice - PMC
Bronchial hyperresponsiveness (BHR) is defined as increased responsiveness in comparison with an expected response. This increased response of the airways can be measured by inhalation of specific or non-specific stimuli, and it should not be expected to be observed in normal subjects.
Airway Hyperresponsiveness in Asthma: Mechanisms, Clinical …
Airway hyperresponsiveness (AHR) and airway inflammation are key pathophysiological features of asthma. Bronchial provocation tests (BPTs) are objective tests for AHR that are clinically useful to aid in the diagnosis of asthma in both adults and ...

2021年7月12日 · Bronchial hyperresponsiveness or airway hyperresponsiveness consists of an increased sensitivity of the airways to an inhaled constrictor agonist.
Bronchial hyper-responsiveness: a technical update
2018年9月6日 · Bronchial hyper-responsiveness (BHR) is often regarded as a ‘hallmark’ of asthma, and bronchoprovocation testing is frequently performed to support a diagnosis of asthma.
Bronchial hyperresponsiveness: the need for a distinction …
Bronchial hyperresponsiveness is currently defined as an increase in sensitivity to a wide variety of airway narrowing stimuli. Most patients with asthma and chronic obstructive pulmonary disease (COPD) exhibit such an enhanced sensitivity.
