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.

Oklahoma City Ranks Ninth for Most Challenging Cities for Asthma

AAFA’s 2021 Asthma Capitals™ Report Lists Most Challenging Cities to Live in the U.S. with Asthma; Oklahoma City takes ninth place for 2021

The Asthma and Allergy Foundation of America (AAFA) recently rolled out its 2021 Asthma Capitals™ report. The report coincided with World Asthma Day, part of National Asthma and Allergy Awareness Month. AAFA’s Asthma Capitals™ report analyzes data from the 100 largest cities in the United States to determine its ranking. Allentown, Pennsylvania takes the top spot as the most challenging place to live for asthma in the 2021 report. Oklahoma City was ranked ninth and Tulsa was 24th.

The ranking is based on three criteria: asthma prevalence, emergency department visits for asthma, and deaths due to asthma. The report also highlights risk factors including poverty, air pollution, access to specialists, pollen counts, medicine use, smoking policies, and the rate of uninsured residents in an area. AAFA previously identified existing “Asthma Belts” which continue to have a grip on the eastern half of the nation, however two western cities – Tucson, Arizona and Fresno, California, are also listed in the top 20 cities for this year’s report. The top 20 Asthma Capitals™ for 2021 are: 1. Allentown, Pennsylvania 2. Baltimore, Maryland 3. Richmond, Virginia 4. Milwaukee, Wisconsin 5. New Haven, Connecticut 6. Cleveland, Ohio 7. Philadelphia, Pennsylvania 8. Dayton, Ohio 9. Oklahoma City, Oklahoma 10. Tucson, Arizona 11. Worcester, Massachusetts 12. Springfield, Massachusetts 13. Columbus, Ohio 14. Birmingham, Alabama 15. Detroit, Michigan 16. Louisville, Kentucky 17. Hartford, Connecticut 18. Boston, Massachusetts 19. Fresno, California 20. Greensboro, North Carolina.

“AAFA produces the Asthma Capitals report and similar research to help improve the lives of the estimated 25 million Americans living with asthma. It’s important to highlight areas which deserve our urgent attention and collective action. This includes the pressing need to develop more programs and policies that will effectively help us reduce stark disparities in asthma based on race, gender, income and where people live,” said Kenneth Mendez, CEO and president of AAFA. “This report also supports the need for climate action. Air pollution, extreme weather patterns, and natural disasters fueled by climate change continue to have a worsening impact on Americans living in certain communities. This is not only a critical area of investigation, but signals exactly where work needs to be done for those with the greatest needs.”

The report also calls attention to the role of the COVID-19 pandemic in determining the rankings. This includes some changes in health outcomes and risk factors like pollen exposure, medicine use, and emergency room visits. In 2020, fewer people experienced pollen allergies due to COVID-19 restrictions, recommendations to stay indoors, and other preventative measures like mask wearing. As a result, use of long-term asthma medicines were also down along with fewer people heading to hospital emergency rooms for asthma.

“The pandemic, economic recession, climate crisis, and racial injustice all had a significant impact on the asthma community in 2020. Despite some varying factors, asthma remains a serious public health threat with an average of 10 people dying each day. At AAFA, we reiterate that’s 10 too many. Most of these tragedies are preventable,” said Melanie Carver, chief mission officer at AAFA. “Stakeholders, policy makers, health officials, communities and individuals around the nation can use this information to join us in our mission to save lives.”

“It’s been an especially challenging year for allergies so far with high pollen and mold spore counts along with high allergy alert days,” said Oklahoma Allergy & Asthma Clinic Board-certified allergist Dr. Laura Chong. “All of these can be triggers for increases in asthma attacks too. It is important to get an evaluation to figure out your triggers and the best strategy to help optimize control of your asthma.”

The 2021 Asthma Capitals™ report is an independent research project of AAFA made possible in part by support from the Pharmaceutical Care Management Association (PCMA) Foundation. For the latest AAFA news and resources go to aafa.org.
