“…Peak expiratory flow meters are simple, handheld personal devices that measure the maximal peak expiratory flow (PEF) that represents just a single point of the flow-volume curve recorded during forced spirometry. 57 , 66 PEF results are expressed in L/min and reflect the airway patency mostly associated with the large conductive airways, and only in a small proportion of the mid-airways; they also account for the strength of the expiratory muscles which exert extrathoracic pressure of the airways. 7 PEF is highly associated with the level of effort, so reliable results can be expected from adherent and compliant patients.…”

“… 7 PEF is highly associated with the level of effort, so reliable results can be expected from adherent and compliant patients. 66 , 67 PEF-meters can be used both to support the diagnosis of asthma and for monitoring purposes. It is also recommended as the part of the Asthma Action Plan (AAP) to assess risk of exacerbations and for treatment adjustments to preserve and maintain control of the disease.…”

Medical devices provide people with some health benefits in terms of diagnosis, prevention, treatment, and monitoring of disease processes. Different medical specialties use varieties of medical devices more or less specific for them. Allergology is an interdisciplinary field of medical science and teaches that allergic reactions are of systemic nature but can express themselves at the level of different organs across the life cycle of an individual. Subsequently, medical devices used in allergology could be regarded as: 1) general, servicing the integral diagnostic and management principles and features of allergology, and 2) organ specific, which are shared by organ specific disciplines like pulmonology, otorhinolaryngology, dermatology, and others. The present position paper of the World Allergy Organization (WAO) is meant to be the first integral document providing structured information on medical devices in allergology used in daily routine but also needed for sophisticated diagnostic purposes and modern disease management. It is supposed to contribute to the transformation of the health care system into integrated care pathways for interrelated comorbidities.

“…Peak flow meters measure how much air an individual can expel out of the lungs in one fast blast of breath . Individuals blow into the device to determine their personal best and then use that number to compare future results . Although studies have not confirmed that a personalized, written asthma action plan improves asthma outcomes compared with verbal education from the clinician alone, asthma experts recommend the use of asthma action plans.…”

“…Although a peak flow meter should not be used as a replacement of spirometry testing for diagnosis of asthma, it is a helpful tool that can be used in the clinic setting to assess asthma control . Asthma is generally considered to be well controlled if the peak flow is at least 80% of the individual's personal best, but a peak flow reading is only part of the person's clinical picture of asthma control …”

“…Individuals should be provided with and instructed on use of a home peak flow meter, and a written asthma action plan that includes information on when to seek medical care should be developed in collaboration with the client . Peak flow meters measure how much air an individual can expel out of the lungs in one fast blast of breath . Individuals blow into the device to determine their personal best and then use that number to compare future results .…”

Asthma is a common condition affecting 8.3% of the adult population in the United States. The disease is characterized by chronic airway inflammation that leads to airway hyperresponsiveness and obstruction that results in coughing, wheezing, shortness of breath, and a feeling of chest tightness. The diagnosis and classification of asthma is based on reported symptoms, physical examination findings, and spirometry. Pharmacologic therapy is prescribed using a stepwise approach that begins with inhaled short-acting beta 2 -agonists for intermittent asthma with the addition of daily inhaled corticosteroids for more persistent cases. Individuals with asthma are reevaluated on a regular basis to monitor symptoms, and pharmacologic treatments are adjusted as needed. Familiarity with the stepwise approach for asthma management and confidence in the efficacy and safety profiles of inhaled medications will assist clinicians in successful management of asthma in the primary care setting. a low-dose inhaled corticosteroid in addition to a shortacting beta 2 -agonist to use as needed for acute symptoms. The clinician demonstrated inhaler usage, provided teaching on avoiding asthma triggers, and developed a written asthma action plan with C.E. A follow-up appointment was scheduled for 4 weeks.Note: This case summary is a composite of elements from different individuals. PATHOPHYSIOLOGYThe pathophysiology of asthma is complex in nature.
