Learn how taking your peak flow regularly can help you spot if your asthma is getting worse and cut your risk of an asthma attack.

Asthma can be a debilitating condition, but there are numerous asthma treatments available. Learn all about what causes and aggravates asthma. Advertisement Asthma can be a debilitating condition, and a number of factors can trigger an atta

Peak expiratory flow rate (PEF) or forced expiratory volume in 1 s (FEV1) monitoring is an important clinical tool to assess the degree of 24-h variation (circadian) in lung function, which correlates with the degree of airway hyperresponsiveness. Peak expiratory flow prediction Peak flow monitoring is recommended for the ongoing management of asthma and during exacerbations. It is less used these days for the initial diagnosis of asthma, clinicians being encouraged to use more accurate measurements of lung function such as spirometry and the fractional exhaled nitrous oxide (FeNO) test. Data on BHR (⩾ 20% fall in FEV1), PEF variability (ampl%mean PEF > 5% on any day during an 8-d period with low air pollution levels) and diary data on upper and lower respiratory symptoms, cough, and phlegm were collected in 189 subjects (48–73 yr). Airway responsiveness and variability in peak expiratory flow (PEF) are widely used as objective diagnostic measures of asthma, but it is not clear how these variables should be calculated or adjusted to obtain the highest diagnostic validity for physician-diagnosed asthma in the community.

2019-07-19 · Asthma is a chronic inflammatory airway disease. Increase in airway inflammation is hypothesised to contribute to worsening of asthma symptoms and deterioration in lung function, resulting in the use of reliever medication. Short-acting β2-agonists only treat the symptoms, whereas an anti-inflammatory reliever is believed to treat both symptoms and the underlying inflammation, thereby

Daily PEF amplitude reflects bronchial hyperactivity and its measurement and expression via indexes of variability is indirect estimation of this phenomenon characterising asthma. The aim of this study is to estimate the validity of some indexes of daily PEF variability (DV) in making asthma diagnosis. 2020-08-12 · Age and height were significantly associated with peak expiratory flows (PEF) in all subgroups.
