Peak Flow Monitoring

What is peak flow?

Peak flow is the measurement of how effectively air moves out of your lungs . A peak flow meter monitors your asthma the way a blood pressure cuff monitors your blood pressure. Measuring peak flow helps determine any narrowing in your airways before you have an actual attack. This allows you to take your medicine before a serious attack develops.

Why is peak flow monitoring so important?

Peak flow monitoring allows you and your doctor to manage your condition effectively. It gives an accurate picture of your condition that allows your doctor to make appropriate decisions regarding the effectiveness of your medicine plan and treatment plan .

Other benefits of peak flow monitoring include the following:

  • Helps you decide whether your condition is serious enough to seek emergency treatment.
  • Allows you to detect early stages of airway obstruction to start immediate treatment.
  • Gives you an accurate picture of the variations in your condition over a 24- hour period. This permits your doctor to prescribe treatment when you need it the most.
  • Helps you differentiate between airway obstruction and other causes of breathlessness like hyperventilation.
  • Allows you to ascertain specific allergens, irritants, or workplace exposures that may cause your symptoms to develop.
  • Enables you to communicate more effectively with your doctor so that he or she can provide guidance over the phone if needed.
  • May be an effective detector to monitor whether your asthma symptoms have stabilized, improved, or deteriorated/worsened.

How do I start?

Most adults and young children can use a peak flow meter.

All it requires is a short, hard blow of air into the meter. Here's how to use the peak flow meter :

  • Place the indicator at the base of the numbered scale.
  • Sit upright or stand up.
  • Take a deep breath .
  • Place the meter in your mouth and close your lips around the mouthpiece. Be sure not to put your tongue in the hole.
  • Blow out as hard and fast as you can.
  • Write down the number that you get.
  • Repeat the above steps two more times.
  • Write down the highest of the three numbers in your asthma diary.

What is the "Three Zone" system?

You need to find your personal best peak flow number. This is the highest number that you can attain over a 2-week period when you feel good and do not have any asthma symptoms. These measurements should be taken when you wake up and in the evening. They should also be taken before and after taking an inhaled medication , if you use one. Keep an accurate record of these readings so that you can discuss them with your doctor.

Peak flow numbers have been put into zones that are set up like a traffic light. Using your personal best peak flow number, you can determine what zone the reading falls in and respond with the appropriate treatment.

For example:

traffic signal with red, yellow, and green lights

GREEN ZONE (80% to 100% of your personal
best number)

The green zone signals all clear. No asthma symptoms are present and you can take your medications as you have been doing.

YELLOW ZONE (50% to 8O% of your personal best number)

The yellow zone signals caution. You may be having an asthma attack that requires an increase in medication, or your doctor may need to change your treatment plan because your asthma is not under control.

RED ZONE (below 50% of your
personal best number)

The red zone signals a medical alert. You should first take your short-acting bronchodilator immediately and then contact your doctor right away.

Be sure to talk to your doctor regarding peak flow monitoring. Your particular zones should be established based on your individual condition.

How do I keep track of my peak flow readings?

It is important to keep a daily diary of your peak flow readings so that you and your doctor can better evaluate your treatment plan . This information can help you to effectively control your condition and lead a more active, healthy life.

Ragweed Season is HERE

Ragweed Season

Ragweed Plants Packed with Pollen

Summer fun can turn to fall misery for millions of people who suffer from seasonal allergic rhinitis (hay fever). Sneezing, stuffy or runny nose, itchy eyes, nose and throat, or worsening of asthma symptoms are common in people with undiagnosed or poorly managed hay fever.

The primary culprit of fall allergies is ragweed pollen. A ragweed plant only lives one season, but it packs a powerful punch. A single plant can produce up to 1 billion pollen grains. These grains are very light weight and float easily through the air.

Fall allergy symptoms used to start in mid-August and run through September. In many parts of the country these symptoms now begin in early August and extend through October. Some studies suggest that rising temperatures and higher carbon dioxide levels contribute to longer growth time of allergen-producing plants. In 2023, OAAC reported high ragweed counts beginning in the third week of August. In fact, on August 28, 2023, we had our first ragweed allergy alert day.

Allergies occur when the body’s immune system treats the allergen, in this case ragweed, as a foreign invader. This starts a chemical reaction which produces and sends histamine throughout the blood stream. These chemicals cause allergy symptoms to develop.

Controlling symptoms
Proper diagnosis is the first step in managing your symptoms. An allergist will give a physical exam, ask about your health history and perform allergy testing to determine exactly what you are and are not allergic to.

Although there is no cure, ragweed allergy can be managed to improve the quality of your life.

The best control is to avoid contact with the pollen. This can be difficult, but resources are available. The National Allergy BureauTM (NAB) tracks pollen counts regionally to help you plan when you should avoid spending a lot of time outdoors. Remember to follow the OAAC on social media for the OKC area. Our counts are collected from the top of our main office building Monday-Friday by our certified pollen counters.

Talk to your doctor about medications that may provide temporary relief from symptoms. Your allergist/immunologist may also recommend immunotherapy (allergy shots) or sublingual immunotherapy (SLIT) allergy tablets, treatment. This long-term treatment approach can significantly reduce the frequency and severity of symptoms caused by allergic rhinitis.

Did you know?

  • The tall goldenrod species of ragweed gets blamed for most of the pollen, but a primary cause of allergy symptoms is the tooth-leaved ragweed that lives low in the grass.
    • Ragweed can be found in almost all states in the United States as well as in Canada.
    • An accurate diagnosis is essential for managing symptoms. Allergy testing performed by an allergist can determine what you are and not allergic to.To the point
    Although often associated with hay fever, ragweed can also cause skin conditions such as allergic contact dermatitis and hives.
