Differential Diagnosis of Acute Asthma. The differential diagnosis of acute asthma includes COPD, bronchitis, bronchiectasis, foreign body, extra-or intra-thoracic tracheal obstruction, cardiogenic pulmonary edema, non-cardiogenic pulmonary edema, pneumonia, pulmonary embolus, chemical pneumonitis, and hyperventilation syndrome [2-3].

For example, if you’re recovering from an asthma attack, or your treatment plan has changed. You may be asked to keep a peak flow diary for a couple of weeks to help your GP confirm an asthma diagnosis. To be sensitive and specific in the diagnosis of occupational asthma, the ABC score requires 2-hourly PEF measurements on eight workdays and three rest days. This is a short assessment period that should improve patient compliance. PEF analysis requiring shorter records for occupational asthma diagnosis Based on a systematic literature search, serial PEF measurement is a feasible, sensitive, and specific test for the diagnosis of occupational asthma, when potential sources of error are understood. Keywords: occupational asthma, peak expiratory flow, sensitivity, specificity, return rate, adequate data quantity PEF: Peak Expiratory Flow, a test that measures the peak expiratory flow rate (PEFR). PFM: Peak Flow Meter, a simple device intended for home or clinic use, which allows a patient with asthma to measure his or her peak expiratory flow rates and compare them to expected ranges.

PEF analysis requiring shorter records for occupational asthma diagnosis 1999-04-01 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. Bronchoprovocation with cold air, methacholine, or exercise (if negative, may rule out asthma) 1. increases by more than 12% and 200mL from baseline (in children, by >12% of the predicted value) after 4 weeks of anti- inflammatory treatment (outside respiratory infections) • The greater the variation, or the more times excess variation is seen, the more confident you can be of the diagnosis of asthma. Obtain PEF in clinic and review PEF record from patient, if available, for personal best, and set up patient’s zones based on PEF values taken for 2-3 weeks to create an asthma action plan If the patient fails to bring in the PEF record, then an action plan will be created using … Quick Reference Charts for the Classification and Stepwise Treatment of Asthma (Adapted from 2007 NHLBI Guidelines for the Diagnosis and Treatment of Asthma Expert Panel Report 3) Asthma severity is the intrinsic intensity of the disease process and dictates which step to initiate treatment. Peak expiratory flow (PEF) monitoring is often used to establish the relationship between occupational exposure and asthma. FEV 1 has been found to be a better physiologic index than PEF in the measurement of airflow obstruction.


Bethesda, MD. National Heart, Lung, and Blood Institute, 2007. 2017-01-01 · Domiciliary morning and night monitoring of PEF (usually as the best of three tests) can be used to demonstrate peak flow variability over a period of time (e.g., 2 weeks) to support the diagnosis of asthma. PEF should be compared with the patient's best value, as normative values are unreliable. 14 1.3.2 Offer a FeNO test to adults (aged 17 and over) if a diagnosis of asthma is 15 being considered.

2021-04-12 · Both clinical experience and published anecdotal evidence suggest a role for targeted, short term PEF monitoring in the diagnosis of asthma, 28, 29 and in identifying triggers of asthma. 15 In our practice, we only use home PEF monitoring in rare cases of diagnostic uncertainty and unstable asthma when exacerbating factors remain unclear.

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 A sensitivity of 68% and specificity of 91% for occupational asthma diagnosis are achieved when the PEF record contains eight workdays, three rest days and at least eight readings per day. More workers should be able to achieve PEF monitoring for a shorter period, making the diagnosis of occupational asthma easier.

Variable peak expiratory flow (PEF) readings can support an asthma diagnosis if there is diagnostic uncertainty after initial assessment, a FeNO test, and/or objective tests to detect airway obstruction. A value of more than 20% variability after monitoring at least twice daily for 2-4 weeks is regarded as a positive result:

A peak flow meter is a handheld device that measures how well air moves out of your lungs. During an asthma episode, your airways often narrow. A peak flow meter can measure this narrowing hours, even days, before you have any asthma symptoms. In fact, a peak flow meter is so sensitive to changes in your airways that it can alert you to breathing issues even better than a doctor can when listening to your lungs with a stethoscope.

The diagnosis of asthma is a clinical one with the history and physical examination being significant, but objective measures, such as pulmonary function testing, can be used to aid in the diagnosis.

PEF Variabilty. 0-14 Variability: Guidelines for the diagnosis and management of asthma.

Peak flow is also used once you have an asthma diagnosis to check how your airways are. You can take your own peak flow and record the readings in a peak flow diary. Your GP or asthma nurse might do a peak flow test at your annual asthma review as part of their routine checks. They will compare the result against your best reading.
