In patients with asthma, the PEF percent predicted correlates reasonably well with the percent predicted value for the forced expiratory volume in one second (FEV 1) and provides an objective measure of airflow limitation when spirometry is not available [ 1,2 ]. PEF monitoring in patients with asthma will be reviewed here.

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.

Obstructive lung diseases include asthma and COPD (chronic obstructive pulmonary disease). The results after taking albuterol (“post-bronchodilator results”) help separate asthma from COPD. Consider asthma if any of the above indicators are present, then confirm with spirometry. If the child is too young for spirometry to be done, diagnosis should be made based on the medical history, physical exam and/or response to asthma treatment. Children with asthma may need additional tests to aid and/or confirm the diagnosis. Se hela listan på myamericannurse.com PEF Peak expiratory flow .

Quality asthma care involves not only initial diagnosis and treatment to achieve asthma control, but also long-term, regular follow-up care to maintain control. Asthma control focuses on two domains: (1) reducing impairment—the frequency and intensity of symptoms and functional limitations currently or recently experienced by a

Asthma was evaluated clinically and by peak flow. fewer asthma symptoms after 3 years as evaluated by clinical diagnosis (odds ratio, 2.52; P < .05).

1, 2 Confirmation of the diagnosis hinges on demonstrating airflow obstruction varying over time. Unlike diseases in which objective numeric values are used to establish a diagnosis (e.g., hypertension, diabetes), asthma is a clinical diagnosis that incorporates genetic predisposition and The diagnosis of asthma in children and adults is based on the recognition of a characteristic pattern of respiratory symptoms, signs and test results and the absence of any alternative explanation for these. Recent findings: In clinical trials, summary measures such as average morning PEF provide only a fraction of the available information about asthma control and treatment response.
