Figure 1 shows the distribution of peak inspiratory flow at R5 and R0 resistance across different current preventer inhalers. Within each preventer group, there was a wide range of values. Against R0 resistance, patients currently using DPIs fared worse than those currently using a pMDI, with a...
Peak expiratory flow (PEF) Patients can easily assess airflow limitation by using a PEF meter and detect and manage worsening of asthma promptly. Daily or weekly variations of PEF can be assessed by daily PEF measurements in the morning and at night. Normal: PEF ≥80% of predicted value. ...
They were asked to halve their usual inhaled steroid dose and long-acting bronchodilator, to discontinue their antileukotriene medication, and to keep a daily symptom diary and record daily peak flow rates using a peak flow meter. They were permitted to use short-acting bronchodilators on an as...
The most frequently investigated home-monitoring device dates back from the pre-technology-era and is the peak expiratory flow meter [15]. Kotses et al. [16] concluded that peak flow only gives a small increment in effectiveness beyond that afforded by symptom monitoring. In the last decade,...

• Measurements of lung function (spirometry or peak expiratory flow) provide an assessment of the severity of airflow limitation, its reversibility, and its variability, and provide confirmation of the diagnosis of asthma. • Measurements of allergic status can help to identify risk factors that...
(predicted FEV1 < 80%, predicted peak expiratory flow rate [PEFR] < 85%, or 20% improvement with bronchodilators), 59% had abnormal radiographic findings consisting of hyperinflation, increased perihilar markings, and peribronchial or peribronchiolar cuffing. Bronchitis and/or bronchiolitis and ...

The technique is simple to use and symptoms and morning pre-bronchodilator peak expiratory provides repeatable and reproducible results in adults and in flow rate (PEF) (Wright's mini peak flow meter). At each visit children as young as 4 years old.26 Although FeNO and the following ...
