- Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways ()
- Bronchial constriction occurs when the muscles surrounding the airways tighten, reducing airflow
- Wheezing, a high-pitched whistling sound during breathing, is a common symptom of asthma caused by the narrowed airways
- Wheezing is often more pronounced during exhalation (breathing out)
- Can be heard with a stethoscope or sometimes even without one in severe cases (audible wheezing)
Shortness of Breath and Chest Tightness
- Shortness of breath, also known as dyspnea, is a feeling of difficulty breathing or not getting enough air
- is a sensation of pressure or constriction in the chest, often described as a squeezing or heavy feeling
- Both shortness of breath and chest tightness are caused by the narrowed airways and increased effort required to breathe
- Can be accompanied by rapid, shallow breathing (tachypnea) as the person tries to compensate for the reduced airflow
- May worsen with physical activity or exposure to triggers (, cold air, stress)
Coughing in Asthma Attacks
- Coughing is another common symptom of asthma, particularly during an attack or flare-up
- Asthma-related coughing is often dry and persistent, occurring more frequently at night or early morning
- Coughing serves as a reflex to clear the airways of mucus and irritants
- However, excessive coughing can further irritate the airways and worsen symptoms
- Coughing may be accompanied by mucus production (sputum), which can be clear, white, or yellow in color
Asthma Medications and Devices
Inhalers and Spacers
- Inhalers are portable devices used to deliver medication directly to the lungs
- Metered-dose inhalers (MDIs) are the most common type, releasing a measured dose of medication as a fine mist when activated
- Spacers are tube-like devices attached to the to improve medication delivery and reduce side effects
- Spacers create a larger chamber for the medication mist, allowing more time for inhalation and reducing the need for precise timing
- Spacers also reduce the amount of medication deposited in the mouth and throat, minimizing side effects like thrush (oral yeast infection)
Peak Flow Meters and Monitoring
- Peak flow meters are handheld devices used to measure how well air moves out of the lungs
- Patients blow forcefully into the meter, which measures peak expiratory flow rate (PEFR) in liters per minute
- Peak flow monitoring helps track asthma control and detect worsening symptoms before an attack occurs
- Patients establish their personal best PEFR when asthma is well-controlled
- A drop in PEFR below a certain percentage of the personal best indicates worsening asthma and the need for adjustments in treatment
Rescue and Controller Medications
- , also known as quick-relief or short-acting bronchodilators, are used to rapidly relieve acute asthma symptoms
- Examples include albuterol (ProAir, Ventolin) and levalbuterol (Xopenex)
- Rescue medications work by relaxing the airway muscles, reducing bronchial constriction, and improving airflow
- , also called long-term control or maintenance medications, are used daily to prevent asthma symptoms and attacks
- Examples include inhaled corticosteroids (fluticasone, budesonide), long-acting bronchodilators (salmeterol, formoterol), and leukotriene modifiers (montelukast)
- Controller medications work by reducing airway inflammation, preventing bronchial constriction, and decreasing mucus production
Asthma Management Strategies
Asthma Action Plans and Trigger Avoidance
- An is a written, personalized guide created by the patient and healthcare provider to manage asthma daily and during flare-ups
- Includes information on medications, triggers, peak flow zones, and when to seek emergency care
- Helps patients recognize worsening symptoms and take appropriate action to prevent or manage attacks
- is a key component of asthma management, involving identifying and minimizing exposure to factors that worsen asthma symptoms
- Common triggers include allergens (pollen, dust mites, pet dander), irritants (smoke, pollution, strong odors), respiratory infections, exercise, and cold air
- Strategies for trigger avoidance may include using air filters, maintaining a clean environment, covering bedding, and warming up before exercise
Breathing Techniques and Emergency Care
- Pursed-lip breathing is a technique used to control shortness of breath and slow down breathing during an asthma attack
- Involves breathing in through the nose and exhaling slowly through pursed lips (as if whistling)
- Helps to keep the airways open longer, allowing more air to flow in and out of the lungs
- Can be used in conjunction with rescue medications to manage symptoms
- Emergency medical services (EMS) should be activated if asthma symptoms are severe, not responding to rescue medications, or if the person is having difficulty speaking or breathing
- Signs of a severe asthma attack include rapid breathing, in full sentences, bluish lips or fingernails (), and drowsiness or confusion
- EMS providers can administer oxygen, nebulized medications, and provide transportation to a hospital for further treatment if necessary
