Pediatric Asthma: Managing Your Child's Asthma in South Florida

Asthma is the most common chronic disease in children, affecting approximately 4.7 million children under 18 in the United States. For families in South Florida, the subtropical climate brings unique challenges: year-round pollen, high humidity, mold exposure, and frequent thunderstorms can all trigger symptoms in young patients. The good news is that with accurate diagnosis, the right treatment plan, and consistent management, most children with asthma lead active, healthy lives.

At the Advanced Asthma Clinic in Plantation, FL, Dr. Frank Hull provides comprehensive asthma care for pediatric and adolescent patients. With over 20 years of experience in pulmonary medicine and access to advanced diagnostic tools including spirometry, exhaled nitric oxide testing, and allergy evaluation, we work with families to build individualized treatment plans that keep children breathing well at home, at school, and on the playing field.

Understanding Childhood Asthma

Childhood asthma involves the same underlying process as adult asthma: chronic inflammation of the airways causes them to become swollen, narrowed, and overly sensitive to various triggers. During an asthma episode, the muscles around the airways tighten (bronchospasm), the airway lining produces excess mucus, and the resulting obstruction makes it difficult to breathe.

However, pediatric asthma differs from adult asthma in several important ways:

  • Smaller airways: Children have proportionally smaller airways than adults, so even mild inflammation and swelling can cause significant obstruction
  • Evolving immune systems: A child's immune system is still developing, which means asthma triggers and severity can change as they grow
  • Difficulty describing symptoms: Young children may not be able to articulate that they feel short of breath or that their chest is tight, making parental observation critical
  • Diagnostic challenges: Reliable spirometry typically requires a child to be at least 5-6 years old, so diagnosis in younger children relies more heavily on clinical history and response to treatment
  • Growth considerations: Treatment plans must account for a child's growth and development, including potential effects of long-term medications

Recognizing Asthma Symptoms by Age

Asthma can appear differently depending on a child's age. Knowing what to watch for helps parents seek evaluation sooner.

Infants and Toddlers (Under Age 5)

Asthma in very young children is often called "reactive airway disease" because a definitive asthma diagnosis is difficult at this age. Signs to watch for include:

  • Recurrent wheezing episodes, especially with respiratory infections
  • A persistent cough that worsens at night or early morning
  • Rapid or labored breathing during normal activities
  • Visible chest retractions (skin pulling in around the ribs during breathing)
  • Reduced feeding or loss of interest in play due to breathing difficulty
  • Frequent respiratory infections that seem to "go to the chest"

School-Age Children (Ages 5-12)

At this age, children can begin to describe their symptoms and perform lung function tests. Common signs include:

  • Coughing during or after exercise, laughing, or crying
  • Wheezing that parents can hear, especially during exhalations
  • Complaining of chest tightness or saying their chest "hurts"
  • Avoiding physical activities or tiring quickly during play compared to peers
  • Nighttime coughing that disrupts sleep
  • Frequent missed school days due to respiratory symptoms

Teenagers (Ages 13-17)

Adolescence brings its own challenges for asthma management:

  • Teens may underreport symptoms or skip medications to avoid feeling "different"
  • Social pressures, vaping, and secondhand smoke exposure can worsen asthma
  • Exercise-induced symptoms may become more prominent with competitive sports
  • Hormonal changes, particularly in girls around menstruation, can affect asthma control
  • Stress and anxiety can trigger or worsen symptoms

Why South Florida Is Challenging for Children with Asthma

The Plantation, FL area and broader Broward County present a unique set of environmental triggers that can make childhood asthma more difficult to control:

  • Year-round pollen: Unlike northern states with a defined pollen season, South Florida's tropical plants and grasses produce pollen throughout the year. Children playing outdoors are exposed daily.
  • Mold abundance: High humidity and frequent rain create ideal conditions for mold growth both indoors and outdoors. Mold spores are a potent asthma trigger in children.
  • Dust mites: The warm, humid climate is ideal for dust mite populations, which thrive in bedding, carpets, and stuffed animals.
  • Air conditioning transitions: Children move frequently between hot, humid outdoor air and cold, dry air-conditioned classrooms, which stresses the airways. This temperature shift is one of the most common triggers in South Florida.
  • Thunderstorm asthma: South Florida averages 70-80 thunderstorm days per year. Storms can rupture pollen grains and release clouds of respirable allergen particles that trigger sudden asthma episodes in children.
  • Cockroach and pest allergens: The subtropical climate supports high cockroach populations, and cockroach allergen is one of the strongest indoor asthma triggers for children, particularly in urban and suburban settings.

How Childhood Asthma Is Diagnosed

Accurate diagnosis is the foundation of effective management. At the Advanced Asthma Clinic, Dr. Hull uses an age-appropriate, step-by-step approach:

Step 1: Comprehensive History

A detailed history is especially important in pediatric asthma. Your doctor will ask about:

  • Frequency and pattern of coughing, wheezing, and breathing difficulty
  • Symptom triggers (exercise, cold air, allergens, infections, emotions)
  • Family history of asthma, allergies, or eczema (atopic triad)
  • Impact on sleep, school attendance, and physical activities
  • Environmental exposures at home and school (pets, mold, smoke, carpet)
  • Response to any previous asthma treatments

Step 2: Physical Examination

Your doctor will listen for wheezing, check for nasal congestion or polyps (signs of allergic disease), examine the skin for eczema, and assess breathing patterns at rest.

Step 3: Lung Function Testing

For children aged 5 and older, spirometry is a key diagnostic tool. It measures how much air your child can exhale and how fast. Additional tests may include:

  • Bronchodilator reversibility: If spirometry shows any obstruction, a short-acting bronchodilator is given and the test repeated. An improvement of 12% or more supports an asthma diagnosis.
  • Exhaled nitric oxide (FeNO): This quick, noninvasive breath test detects eosinophilic airway inflammation. Elevated FeNO levels in children (above 20 ppb) suggest allergic airway inflammation consistent with asthma.
  • Peak flow monitoring: Older children may use a peak flow meter at home to track daily airway function and identify patterns.

Step 4: Allergy Testing

Because allergic asthma is the most common type in children, allergy testing (skin prick or blood IgE panels) helps identify specific triggers. In South Florida, common culprits include dust mites, mold (Alternaria, Aspergillus), tree and grass pollen, cockroach allergen, and pet dander. Knowing your child's specific triggers allows for targeted avoidance strategies.

Treatment: A Stepped Approach

Pediatric asthma treatment follows evidence-based guidelines that use a "step-up, step-down" approach. The goal is to achieve and maintain control using the lowest effective dose of medication, then step down when symptoms remain stable.

Quick-Relief (Rescue) Medications

Every child with asthma should have access to a short-acting beta-agonist (SABA) such as albuterol for acute symptom relief. These inhalers work within minutes by relaxing airway muscles. However, needing a rescue inhaler more than twice a week for symptoms (not counting pre-exercise use) is a sign that the child's asthma is not well controlled and the treatment plan should be reassessed.

Controller Medications

For children with persistent asthma symptoms, daily controller medications reduce the underlying airway inflammation:

  • Low-dose inhaled corticosteroids (ICS): The first-line controller for most children with persistent asthma. When used at recommended pediatric doses, ICS have an excellent safety profile with minimal systemic effects. Learn more about steroid-sparing strategies.
  • Leukotriene receptor antagonists: Montelukast may be used as an alternative or add-on controller, particularly in children with concurrent allergic rhinitis.
  • Combination inhalers (ICS + LABA): For children aged 4 and older whose asthma is not controlled on ICS alone, a long-acting beta-agonist may be added. These are always used together with an anti-inflammatory, never alone.
  • Long-acting muscarinic antagonists (LAMA): Tiotropium is approved as add-on therapy for children aged 6 and older with poorly controlled asthma.

Inhaler Technique and Delivery Devices

Correct inhaler technique is critical in children, and the delivery device should match the child's age and ability:

  • Nebulizers: Best for infants and toddlers who cannot coordinate an inhaler. The machine converts liquid medication into a fine mist breathed through a mask or mouthpiece.
  • Metered-dose inhalers (MDI) with spacer: Recommended for children aged 4 and older. The spacer chamber holds the medication so the child does not need to coordinate pressing and breathing simultaneously.
  • Dry powder inhalers (DPI): Suitable for older children and teens who can generate sufficient inspiratory force. No spacer needed, but technique must be taught carefully.

At every visit, Dr. Hull's team reviews and demonstrates proper inhaler technique. Studies show that up to 80% of patients use their inhalers incorrectly, significantly reducing medication effectiveness.

Biologic Therapies for Severe Pediatric Asthma

A small percentage of children have severe asthma that remains uncontrolled despite optimal use of standard medications. For these patients, biologic therapies offer a targeted approach:

  • Omalizumab (anti-IgE): Approved for children aged 6 and older with moderate-to-severe allergic asthma. Given by injection every 2-4 weeks.
  • Dupilumab (anti-IL-4/IL-13): Approved for children aged 6 and older with eosinophilic asthma or oral corticosteroid-dependent asthma.
  • Mepolizumab (anti-IL-5): Approved for children aged 6 and older with severe eosinophilic asthma.

Biologics can dramatically reduce asthma attacks, emergency visits, and the need for oral steroids. They are administered at the clinic, and your child is monitored during and after each treatment.

Allergen Immunotherapy

For children whose asthma is driven by specific allergens, immunotherapy (allergy shots or sublingual tablets) can modify the immune response over time, reducing sensitivity to triggers. This approach is particularly valuable in South Florida, where year-round allergen exposure makes complete avoidance impossible.

Building a School Asthma Action Plan

Children spend a significant portion of their day at school, making a comprehensive asthma action plan essential. Florida law allows students to carry and self-administer prescribed asthma inhalers at school with proper documentation.

An effective school plan includes:

  • Green zone (doing well): Daily controller medications, no symptoms, full participation in activities
  • Yellow zone (getting worse): Increased cough or wheeze, rescue inhaler instructions, when to call parents
  • Red zone (emergency): Severe breathing difficulty, administer rescue medication immediately, call 911
  • Trigger avoidance instructions: Specific triggers the school should help your child avoid (e.g., staying indoors during high pollen or mowing, avoiding gym on poor air quality days)
  • Pre-exercise medication: If prescribed, instructions for using a rescue inhaler 15-20 minutes before PE or recess
  • Emergency contacts: Parent, physician, and backup contact numbers

We provide a completed, signed action plan that can be given to the school nurse, teachers, and coaches. We recommend updating the plan at the start of each school year or whenever the treatment regimen changes.

Clinical Trials for Pediatric Asthma

The Advanced Asthma Clinic participates in clinical research trials studying new asthma treatments, including therapies specifically designed for pediatric patients. Clinical trials may offer access to innovative medications before they are widely available, with close medical monitoring throughout participation. Our sister facility, Lung Research Florida, currently enrolls participants in studies for severe asthma and other respiratory conditions.

Practical Tips for South Florida Parents

  • Monitor air quality daily: Check AirNow.gov or local weather apps before outdoor activities. Keep children indoors on orange or red air quality days.
  • Control indoor humidity: Use a dehumidifier to keep indoor levels between 30-50%. This reduces dust mites and mold, two of the most common pediatric triggers in South Florida.
  • Create an allergen-reduced bedroom: Encase pillows and mattresses in dust mite-proof covers, wash bedding weekly in hot water, remove carpet if possible, and keep stuffed animals to a minimum or wash them regularly.
  • Manage the indoor-outdoor temperature shift: Have your child take a few slow breaths through their nose when moving from hot outdoor air to cold air conditioning. A light scarf over the mouth can help in heavily air-conditioned buildings.
  • Prepare for storm season: During thunderstorm season (June through October in South Florida), keep windows closed during and after storms and ensure your child has their rescue inhaler accessible.
  • Address pest allergens: Use integrated pest management to reduce cockroach exposure. Seal food, fix leaks, and seal cracks around pipes and baseboards.
  • Stay on top of medications: Adherence to daily controller medications is the single most important factor in preventing asthma attacks. Use reminders, reward charts for younger children, or phone alarms for teens.
  • Get the flu and COVID vaccines: Respiratory infections are the leading trigger for asthma attacks in children. Annual influenza vaccination and staying current on COVID-19 vaccination are recommended for all children with asthma.

When to See a Pediatric Asthma Specialist

Your child should be evaluated by a pulmonary specialist if:

  • They have had more than one episode of wheezing, especially triggered by respiratory infections
  • A chronic cough lasts more than four weeks, particularly if it worsens at night
  • They frequently need a rescue inhaler (more than twice a week)
  • Asthma symptoms are not well controlled despite using prescribed medications
  • They have visited the emergency room or been hospitalized for breathing problems
  • Asthma is limiting their ability to participate in sports, play, or school activities
  • They have a strong family history of asthma, allergies, or eczema and are showing early symptoms

Your child's first visit at the Advanced Asthma Clinic includes a thorough history, age-appropriate lung function testing, and development of a personalized treatment plan.
