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.

AAFA’s 2024 Allergy Capitals™ report names most challenging cities for living with allergies, OKC – Fifth; Tulsa – Sixth in the top Ten

Washington D.C., March 14, 2024 — The Asthma and Allergy Foundation of America (AAFA) released its 2024 Allergy Capitals™ report detailing the most challenging cities in the United States for living with allergies. The full report can be found at allergycapitals.com.

This year, Wichita, Kansas takes the top spot due to its higher-than-average tree and grass pollen, higher-than-average medicine use, and limited access to allergy specialists. The top 10 Allergy Capitals™ for 2024 are: 1. Wichita, KS; 2. Virginia Beach, VA; 3. Greenville, SC; 4. Dallas, TX; 5. Oklahoma City, OK; 6. Tulsa, OK; 7. Richmond, VA 8. Des Moines, IA; 9. Raleigh, NC, and 10. Fayetteville, AR.

This year’s report again calls attention to the urgency of the climate crisis. Due to climate change, growing seasons start earlier and last longer than they did just 30 years ago. Some parts of the United States now experience pollen (tree, grass, or weed) year-round. Warmer temperatures also trap heat in urban areas, increase air pollution, and stimulate pollen production.

“Climate change fuels a perfect storm of conditions that make allergy season worse for people with pollen allergy,” said AAFA President and CEO Kenneth Mendez. “Longer growing seasons mean more exposure to pollen allergy triggers. Additionally, pollen counts tend to rise with warmer temperatures. Now, we see both more days of exposure to pollen and higher daily pollen counts leading to more intense, longer-lasting symptoms.”

AAFA’s 2024 Allergy Capitals™ report provides insight into factors impacting seasonal allergies. The report ranks the 100 most populous cities in the contiguous United States by their:

  • Tree, grass, and weed pollen scores
  • Over-the-counter allergy medicine use
  • Availability of board-certified allergists/immunologists 

Experts say a range of treatment options are available for people dealing with seasonal allergies this spring.

“Over-the-counter medicines can help manage symptoms,” said allergist Dr. Neeta Ogden, spokesperson for AAFA. “Working with a specialist can help you develop the best treatment plan.”

While the symptoms of pollen allergy can be managed, they are a significant health concern. Seasonal allergies can even lead to hospitalization if they trigger an asthma episode.

“Our pollen season continues to begin earlier each year,” said Dr. Claire Atkinson, a board-certified allergist with the Oklahoma Allergy & Asthma Clinic (OAAC). “We’ve already had several allergy alert days this year and we’ve not even made it to the official start of Spring. We want to encourage people who are suffering to see their medical provider and consider making an appointment with an allergist.”

A board-certified allergist can diagnose allergies, and determine the specific triggers that cause them, through simple tests. The allergists at OAAC evaluate and manage patients of all ages. The main clinic is on the Oklahoma Health Center campus. For patient convenience, satellite offices are in Edmond, Norman and Yukon.
