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.

Do you have the winter sniffles?

5 ways you can manage indoor winter allergies

Do you suffer from itchy eyes, a runny nose or a scratchy throat during winter? Do you often find yourself coughing, sneezing and having trouble breathing? Chances are you may have indoor allergies.

Allergens are not just found outside in trees or grass. The indoors can host many triggers like mold in pipes, pet allergens, and dust mite and cockroach allergens.

Indoor allergies are a year-round problem, but you’ll notice them more during the winter because you spend more time at home. Also, because of the colder weather, you’re likely keeping doors and windows shut to keep the cold out. By doing that, you’re also sealing allergens indoors with you, and your heating system will recirculate the indoor air and any allergy triggers.

You don’t have to accept indoor allergies as an inevitable fact of the winter season. Using these five tips from the American College of Allergy, Asthma and Immunology (ACAAI), you can be proactive and manage your winter allergies.

1. Clean regularly
It may seem like a simple solution, but cleaning house is one of the easiest ways to deal with indoor winter allergies. Dust, mold, pet dander and dust mite and cockroach droppings can hide anywhere and cause sneezing, coughing and congestion.

To limit your exposure to these indoor allergens, keep a regular cleaning schedule. Dust and vacuum frequently, especially under and behind furniture, where allergens can easily build up. Wipe down counters and other surfaces that you use often. During the holidays, wipe off holiday decorations, especially if you’ve stored them in areas where dust and mold proliferate.

2. Reduce pet allergy triggers
It can be difficult to balance your love for your pets and indoor allergy management. Just like you, your pets are spending more time indoors, increasing your exposure to pet dander and saliva.

While you may enjoy snuggling with your pets before bed, keeping them out of the bedroom will help with any allergies you experience at night that can disrupt your sleep. During the day, keep the door to your bedroom closed, so your furry family members aren’t tempted to go in.

When petting your cat or dog, make sure to wash your hands afterward, so you don’t accidentally touch your face and provoke an allergic reaction. Finally, remember to groom your pets regularly to reduce indoor air allergens.

3. Protect your bedding from dust mites
According to the ACAAI, dust mites live and multiply in warm, humid places and are often found in pillows, mattresses, carpeting and upholstered furniture. Even if your home is visibly clean, dust mite allergen particles are too small to be seen.

Use mite-proof zippered cases for your mattress and pillows to limit your exposure to dust mites. Every week, wash and change your sheets, blankets and other bedding in hot water to eliminate any lingering dust mite droppings.

4. Find and prevent indoor mold
Did you know that there are roughly 1,000 species of mold in the U.S.? Many molds aren’t visible to the naked eye, and mold spores can cause allergic reactions when they become airborne. Because mold can grow in your basement, bathroom, under the sink and anywhere with running water, avoiding mold allergens can be difficult.

If you suspect you have indoor mold, it’s best to contact a professional who can find and clean up existing mold in your home. To prevent mold from growing inside your home, quickly stop and clean up any leaks. Also, make sure to reduce moisture and humidity in bathrooms and kitchens. If humidity control is a problem, consider a dehumidifier.

5. Find an allergist
Consulting an allergist is the best way to identify and treat your winter indoor allergies.

“Allergists are the best trained medical professionals to treat allergies and asthma,” said Kathleen May, MD, ACAAI president. “They can help you get tested, get treated and get better so you can enjoy the holiday season and beyond.”

After a consultation, your allergist may perform tests to diagnose your allergies and identify potential causes. An allergist can also prescribe antihistamines and other allergy treatments to give you relief from your allergic symptoms.

Using these five tips, you can better manage your indoor allergies this winter so you can enjoy the cozy colder months without suffering from allergies.
