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.

Winter Allergies Making Us Miserable

If you recently moved to Oklahoma thinking you would be safe from winter allergies, think again. Certain trees have an aggressive blooming season in the winter months. Cedar pollen can cause a myriad of symptoms including headache, conjestion, losing voice, sinus pressure, itchy eyes, post nasal drip, earaches, sore throat, and increased asthma symptoms.
OAAC’s Board-Certified Allergist Dr. Laura Chong says cedar pollen kicks in especially during the December, January and February months.
“It’s kind of an unusual allergen because most people think spring when tree pollen is wafting through the air,” she said. “Cedar pollen pollinates in the winter months catching many people by surprise.”
“Try to stay inside especially during windy days and make sure the pollen is washed off your body before you go to bed,” said Dr. Chong. “Treatments can vary for each person. Typically the first line of defense is to try over the counter antihistamines or discuss with your physician about prescription options.”
If, however, you are still struggling and miserable, it may be time to be allergy tested and a course of action of immunotherapy (allergy shots) may be in order to help build resistance to the allergen.
Ways to Reduce Your Exposure to Cedar Pollen
Dr. Chong suggests a proactive approach in dealing with cedar pollen allergies.
Install a premium, high efficiency particulate air (HEPA) filter to remove bacteria, mold and other allergens and to improve indoor air quality.
Vacuum daily and preferably with a HEPA-filter vacuum cleaner.
White vinegar is your friend (plus very cost effective). Spray air filters, vents and air returns with white vinegar. Wipe with a clean cloth periodically to remove pollen and other allergens.
On these warm Oklahoma winter days; it is tempting to open the windows for fresh air to be let inside your home. Dr. Chong recommends closing windows and doors to keep the pollen out and to drive with your car with its windows up.
Wipe down surfaces that collect pollen such as your furniture and other areas with a clean cloth and don’t forget your pets!
“Give your pets a quick wipe down to remove pollen when coming indoors,” said Dr. Chong.
After spending time outdoors in the pollen, Dr. Chong says after showering, changing clothes to remove any remaining residue will be helpful. She adds to not line-dry clothes outside when pollen counts are high.
“Check the OAAC website and social media for the daily pollen reports,” Dr. Chong said.
