Mini Wright Peak Flow Meter

Product Information

If you have a respiratory condition or suspect that you might have one, you can get a spirometry test at your doctor’s office. You can also do a self-test at home using an over the counter spirometer. The first choice for Peak Expiratory Flow measurement of healthcare professionals worldwide, the Mini-Wright is the original portable peak flow meter and has been a globally recognised brand for many years: Measuring your peak flow before and after exposure to a possible asthma trigger, such as something you're allergic to or a substance you're exposed to at work, may also show if anything in particular causes your symptoms. How to measure your peak flow This should be repeated 3 times, and the highest of the 3 measurements should be recorded as your peak flow score.

To interpret the significance of peak expiratory flow measurements, a comparison is made to reference (normal, predicted) values based on measurements taken from the general population. Various reference values have been published in the literature and vary by population, ethnic group, age, sex, height and weight of the patient. For this reason, tables or charts are used to determine the normal value for a particular individual. More recently, medical calculators have been developed to calculate predicted values for peak expiratory flow. There are a number of non-equivalent scales used in the interpretation of peak expiratory flow. [4]

A significant difference between your score and a normal score, or a difference in your scores in the morning and evening or when your symptoms are good and bad, may suggest you have asthma. In 2004 the UK switched from the original Wright scale to the newer, more accurate European scale. Wright values may be converted to the EU scale using the following formula: [9] EU = 50.356 + 0.4 W + ( 8.814 × 10 − 4 × W 2 ) − ( 1.116 × 10 − 7 × W 3 ) {\displaystyle {\text{EU}}{=}50.356+0.4W+(8.814\times 10 What's considered a normal score depends on your age, height and sex. Ask your GP or asthma nurse for more information on what would be considered a normal score for you. Microlife PF-100 comes with software that you can load onto a laptop. Once you install the software, use the included USB cable to transfer readings from the spirometer to your PC for storage and analysis.

Write down the Highest of your three readings in the correct column onto the chart provided. If the readings are more than 20 units apart, then take some more readings, but always write down the highest. After your first reading has been recorded, repeat the entire process two more times. Make sure to slide the indicator down to the bottom before taking each additional reading.Hold the peak flow meter lightly, with the gauge uppermost and ensure that your fingers are kept away from the gauge. A small portion of people with asthma may benefit from regular peak flow monitoring. When monitoring is recommended, it is usually done in addition to reviewing asthma symptoms and frequency of reliever medication use. [2] Peak flow meters have a mouthpiece you forcefully blow into with one powerful breath. The meter measures the force you expel air in liters per minute (L/m). An indicator on the meter moves in response to the force of your breath to a spot along a numbered scale. To get your personal best peak flow number, your doctor will have you use the meter at least twice a day. This may be first thing in the morning, before you use asthma medication, and once again in the afternoon or evening.

Place the mouthpiece into your mouth and close your lips around it tightly. Blow Out, as Fast and as Hard as possible. Many spirometers have an integrated peak flow meter, allowing them to offer both FVC/FEV and PEF readings. 2. Reusable Mouthpiece hold the peak flow meter so it's horizontal and make sure that your fingers are not obstructing the measurement scaleBoth FVC and FEV help diagnose any obstructions or restrictions in your airways. FVC measurements tell if there’s any obstruction while FEV tells the severity of the obstruction. A protective cap covers the meter when it’s not in use and makes it safer to carry around in your bag. It also includes a foldout arm that holds the meter upright for easier reading. What we like about it: When you’re getting your asthma symptoms under control: If your asthma is not well controlled, you might take peak flow readings at least once daily, at the same time each day. You may also benefit from taking readings several times per day, such as first thing in the morning and right before bed. A peak flow test involves blowing as hard as you can into a small handheld device called a peak flow meter.

Knowing your personal best peak flow number is essential for controlling asthma. Changes in this number can alert you that your condition is worsening or that a change in your treatment plan is needed. Once you’ve determined your personal best peak flow number, you and your doctor can establish a game plan for using the meter and data it provides. This will include establishing your personal peak flow zones. The spirometer itself has internal memory. It stores up to 240 measurement values, with a data and time for each. This makes it easier to analyse readings and determine trends once you transfer data to a computer. Speak to your GP or asthma nurse if you've been diagnosed with asthma and don't have a personal action plan, or if you're concerned about your peak flow score and don't know what to do. Philips PersonalBest is a peak flow meter. It only measures peak expiratory flow (PEF) within a range of 60 to 800 litres/min.Your personal best is the highest monitor reading you record during this timeframe. This number is important, because it indicates how well you’re able to breathe when your airways are clear and have no asthmatic symptoms. Ensure that the white plastic mouthpiece is securely placed into the end of the barrel of the peak flow meter. Set the indicator to Zero. On peak flow charts, estimated personal best peak flow starts at 43 inches. If your child is shorter than 43 inches, talk with their pediatrician about using a peak flow meter and other options. Can a peak flow meter help me identify asthma triggers in my environment?
