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.

Food Allergies and Theme Parks

By Eve Chen, USA TODAY

There’s a lot more to theme park food than funnel cakes and turkey legs. Many parks pride themselves on their array of dining options for guests, but not just for flavor. More than 6% of Americans have a food allergy, according to the Centers for Disease Control and Prevention’s National Center for Health Statistics. The most common food allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame, according to the U.S. Food and Drug Administration. With those, allergy-safe options can be a matter of life and death.

“I had my first reaction when I was a baby to nuts, and I’ve had serious reactions since that have brought me to the ER – thankfully not too many in recent years,” said Allie Bahn, who helps travelers with food allergies through her Miss Allergic Reactor website and Allergy Travels Facebook group. Bahn has four of the top nine food allergies and other specific allergens, like potatoes. “It can be certainly life-threatening, so it’s different than avoiding foods just because of something bothering your stomach.”

Here are seven ways travelers with food allergies can safely navigate theme parks and what parks are doing to help:

Do your research.

Some parks flag top allergens on their websites and apps.

“It’s listed by restaurant, by item, and it talks about each item what would be the allergen that could be present in that item … A lot of folks who have been living with allergies know what they can and can’t eat, and they’re just looking for a map of ‘Where can I get what I need?’ ” said Cedar Fair corporate chef Charles Walker, who helped roll out new dietary guides for guests earlier this year. As someone with food allergies himself and family members with food allergies, Walker added, “This was near and dear to my heart to really make sure this guest-facing platform was very user-friendly.”

For more personalized help, Cedar Fair’s parks and many others have phone lines and email addresses listed on their websites just for guests with special dietary needs.

“I’m a big fan of contacting places ahead of time,” Bahn said.

Don’t go hungry.

Bahn recommends eating a hearty meal before heading to the park. “So you already have something nice and warm in your stomach, hoping that you’ll be able to find something (else) when you’re there,” she said. She also recommends having plans for a meal after leaving the park, so at least those two meals are covered.

Pack snacks. Not all parks allow outside food, but when permitted, Bahn recommends packing snacks for backup. “Don’t make assumptions that you definitely can’t eat. I think there’s always the ability to try to do as much research ahead of time and then see how it goes once you get there, but having a plan in place is always really helpful,” she said.

Always carry medication or epinephrine. Bahn says she’s carried an epinephrine auto-injector with her for as long as she can remember. “Don’t lock it up in a locker where you can’t quickly access it in case of an emergency,” she said. “It should be on you at all times.”

Ask questions.

“Ask if they have ingredients that you can see,” Bahn said. Some park restaurants have binders of ingredients guests can look at, but it’s best to confirm everything is up to date with chefs, who are happy to speak with guests with food allergies. Sometimes, when creating menus, chefs will intentionally avoid using common allergens like peanuts to make foods more accessible. Chefs can also sometimes adjust dishes for allergies.

“Our festival chefs will go through (the menu) and make sure, based off of the dietary needs, if a dish is safe, if there’s anything (the guest) can have from those kiosks, or if there’s a way, we can make that dish for them safe,” said Kevin Downing, executive chef of EPCOT Festivals at Walt Disney World. Cedar Fair’s Walker echoed, “If you have a very, very specific allergy, we’ll do whatever we can to accommodate.”

Advocate for yourself.

“Explain your food allergies. Advocate for yourself,” Bahn said. She recommends carrying a Chef Card that can be given to chefs, stating each allergy, its severity, and the need for clean utensils and surfaces to be used in food preparation to avoid possible cross-contamination. “It makes everybody’s life, I think, a lot easier and really gets the point across that this is a severe food allergy and not just dietary preference,” she said.

When an allergy-related order comes into Connections Eatery kitchen at EPCOT, Chef Scott Tosh said. “It prints up special, so the special diets-trained cast member will prepare that food. We put an allergy pick in it. If there’s two items – one’s allergy, one’s not – we serve them with separate trays.” Bahn said Disney parks have always been great with her needs, even when she was a kid and people were generally less aware of food allergies.

Trust your gut.

Bahn recommends double-checking all food before digging in.

“I think I have been able to sort of save myself from some potential reactions because of advocating and double checking, trusting my gut,” Bahn said of no place in particular. “There’s plenty of times where I’ve decided not to eat, even if I’ve ordered something because I just felt like I didn’t get all my questions answered in a way that I felt was safe. And that’s OK too. Being able to politely and kindly decide not to eat and walk away and make a different plan is OK, as well. It’s your safety. It’s your health.”
