The median number of doctor consultations was reduced from to in the peak flow group and from to in the symptoms only group. CONCLUSIONS--The peak flow meter was not the crucial ingredient in the improved illness of the two by: frequency analysis, we analyze peak-flow data.
But, “peak-flow frequency analysis” and “flood-frequency analysis” often are used synonymously. Background concepts and terminology In some cases, the distinction between “flood frequency analysis” and “peak-flow frequency analysis” can be important (eg., ice-jam issues).
When to Use a Peak Flow Meter The frequency that you and your child record peak flow numbers depends upon the severity of the asthma, the season, the pattern of symptoms and other factors specific to each person. People with moderate, severe or unstable asthma may need to record peak flow values twice a day.

Portable design allows use anywhere Features a fold. Peak flow meter: A peak flow meter is a tool that can help you and your care-provider manage your asthma. They are often very useful in helping people if they are unsure if they are having problems with their asthma.
Make sure ask your health-care provider to assist you if you are having problems using your peak flow meter. Peak flow monitoring is recommended in the diagnosis of asthma and exacerbations. Over the last decade there has been much debate as to whether routine self-monitoring of peak flow for patients with asthma improves management.
There is only low to moderate evidence that peak flow readings are related to symptoms .Educating the patient in Author: Dr Colin Tidy. Using a peak flow Using a Peak Flow Meter A peak flow meter is a device that measures how well air moves out of your lungs. During an asthma episode the airways of the lungs begin to narrow slowly.
The peak flow meter can be used to find out if there is narrowing in the airways, hours, even days, before you have any symptoms of asthma. Peak-flow meter: This hand-held device measures air flow (how fast air is blown out of the lungs).Patients can use peak-flow meters to measure their own air flow regularly.
The use of a peak-flow meter allows patients to obtain a much earlier indication of an oncoming attack, for example, of exercise-induced asthma, a type of asthma typically triggered by exercise.
Measuring Your Peak Flow Rate A peak flow meter is a portable, inexpensive, hand-held device used to measure how air flows from your lungs in one "fast blast." In other words, the meter measures your ability to push air out of your lungs. Peak flow meters come in two ranges to measure the air pushed out of your lungs.

by: A peak flow meter helps you check how well your asthma is controlled. Use it every day, and keep track of the results to help your doctor learn about your asthma.
This may also help you determine if your asthma is getting worse, even before you have symptoms. Peak flow versus symptoms in management Adams et al. A randomized trial of peak-flow and symptom-based action plans in adults with moderate-to-severe asthma.
Respirology ;6(4)– (The University of Adelaide, The Queen Elizabeth Hospital Research Foundation) Prospective, randomized controlled trial () Age >16 yr, mean = yr. Monitor your peak flow Your peak flow rate is 80–% of your personal best. Your asthma is under reasonably good control—continue your prescribed program of management.
Your peak flow rate is 50–80% of your personal best. Your airways are narrowing, and you may be coughing or wheezing. Increasing your medication is recommended. These are called your asthma peak flow zones. All of this information should be recorded in your personal asthma action plan.
The color coded zones on a peak flow meter are similar to the signals on a traffic light representing safety, caution and danger, which is an indication of whether an individual’s asthma is under control. How to use a Peak Flow Meter 1. Peak flow meter What is a peak flow meter.
To use a peak flow meter your child should follow these steps: A peak flow meter is a device that measures how well air moves out of the lungs. Many different types of meters are available. Place the marker at the bottom of the scale. Stand up or sit up. Predictive Normal Values have been calculated for women and men of different ages and heights, and have been adapted (with agreement from the original Authors) for use with the new EU Scale / EN peak flow meters.
As a general rule, if your average reading is frequently one-third or more below your best it may mean that your asthma is not. Good control means you feel good and do not have any symptoms. The personal best PEF is the number to which all other peak flow readings you obtain will be compared.
To find the personal best peak flow number, take peak flow readings: • Twice a day for two to three weeks • At the same time in the morning and in the evening.
The difference between peak flow means of A and C was l/min (95% CI: –, PCited by: VCHCP considers peak flow meters to be durable medical equipment (DME)1.

7 Instruct the patient to hold the peak flow meter vertically being careful not to block the opening. Peak flow meters are helpful for monitoring breathing problems due to asthma, and therefore many new asthma patients are curious how to use a peak flow meter and to learn what peak flow meter readings mean.
This article provides a summary of these topics. What is a Peak-Flow Meter. It is an instrument that measures Peak Expiratory Flow Rate (PEFR). PEFR is the amount of air a person can blow out during a forced expiration after taking in as full a breath as possible. A peak flow meter for an asthma patient is like a thermometer for a patient with fever.
You may. In the original description of the Armstrong mini-Wright device, documentation of an underestimation of peak flow of 17 percent was made, though allowance for this was provided in calibration. 10 Subsequent studies showed correlation between the standard Wright and mini-Wright peak flow meters, but the study design involved the comparison of Cited by: Determining a Consistent Peak Flow Level of Control for a WWMP The peak flows corresponding to the 2 y, 5 y, and 10 y LOS at each flow meter evaluated in this analysis are tabula ted in Table.
