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.

Making Halloween Fun for Everyone

When a child has a food allergy, holidays can be especially tough for both the child and the child’s family, says Oklahoma Asthma & Allergy Clinic’s Board-Certified Allergist Dr. Maya Gharfeh.

“Holidays are such an important and fun part of childhood,” said Gharfeh. “One of the most important things of raising a child with a food allergy is to not let him or her feel different or isolated because of the food allergy. Instead, we adapt and still let the holiday be as fun as possible.”

The Teal Pumpkin project is an initiative created by the Food Allergy Research and Education (FARE) network to promote a safe Halloween for all including those with a food allergy. It encourages families to place a teal pumpkin on their doorstep to let families know they have non-food treats available for kids with food allergies. Those who wish to participate can register their home address on the FARE website so families can pre-plan their trick or treating.

Any food allergy is potentially life threatening. An accidental exposure through ingestion of a food allergen may quickly lead to a life-threatening situation where a child would need emergency medication – like epinephrine – for survival.

As the mother of a child with a food allergy, Gharfeh has first-hand knowledge. She suggested ideas they’ve done to make a happier Halloween for their daughter.

“We have a rule of no eating or snacking on candy while trick or treating. We go house to house and collect treats as normal. Once we get home, we dump them out and I sort the candies into safe and non-safe, specific for my daughter,” Gharfeh said.

She always keeps safe treats at home for a swap out for those unsafe ones.

“No one wants a half-full Halloween basket,” she said.

Non-food items for those swap outs could include stickers, glow in the dark bracelets and necklaces, Halloween pencils, spider rings, etc.

“Since my daughter has a nut allergy, we try to stay away from most of the chocolate candies and stick with sugar candies such as Skittles or Jolly Ranchers,” Gharfeh added. “We always carry our emergency epinephrine device with us while trick or treating to be ready for an emergency.”

Other ideas for making Halloween safer, Gharfeh says, includes hosting your own Halloween party with allergy safe food treats and non-food items as treats. She encourages families to educate their neighbors and friends about the Teal Pumpkin project. Volunteer for school positions to allow more involvement in choosing snacks/treats for holidays such as Halloween.

“Kids love painting pumpkins,” Gharfeh said. “By inviting your neighbors to participate, you have provided an opportunity to ensure some safe stops for your food allergic littles in your neighborhood.”

FARE recommends has these ideas to celebrate the teal pumpkin project:

  • Decorate your front door. Grab some teal plastic pumpkins (available at local retailers), festive decorations and transform your door. Get your whole neighborhood involved.
  • Host a virtual Halloween party. Staying inside this year? Plan a virtual party so kids can dress up and show off their costumes. Make the party even more interactive by playing fun games online like bingo or trivia.
  • Set up a craft and activity station and let the kids loose! From coloring sheets to word matches, FARE has printable resources for getting kids excited about Halloween.
  • Halloween Scavenger Hunt – get your kids outside and moving. Take a walk or drive around to try and spot sooky sights. Bonus points for spotting teal pumpkins.
  • Stay in for a scary movie night. Invite your friends and neighbors over to watch your favorite Halloween movie.
  • For food allergy friendly recipes, check out the FARE website www.foodallergy.org

If families suspect their child might have a food allergy, Gharfeh says, “Come see a board-certified allergist. We want to help not only diagnose but also to help you, your child, and your family know what a food allergy means and the steps to ensure a safe, healthy and fun childhood, even with a diagnosis of a food allergy.”Teal Pumpkin Campaign
