Signs and Symptoms of Asthma Quiz

Signs and Symptoms of Asthma

• Cough, often productive, indicating possible mucus presence in bronchi.
• Chest tightness and difficulty breathing (dyspnea), resulting in shortness of breath.
• Patients may struggle to finish sentences due to breathlessness during conversation.
• Use of accessory muscles (scalenes, sternocleidomastoid) noted when breathing difficulty is severe.
• Percussion may reveal hyperresonance of the lungs due to air trapping (obstructive lung disease).
• Auscultation typically reveals wheezing, particularly during expiration; wheezing alone is not solely indicative of asthma.

Sputum Analysis

• Productive cough can yield sputum for analysis, revealing:
  • Curschmann spirals: Mucus casts within bronchioles, formed by mucus buildup and epithelial cells.
  • Charcot-Leyden crystals: Breakdown products of eosinophils indicating allergic response.

Diagnostic Protocols

• Pulmonary Function Tests (PFTs) are the gold standard for diagnosis:
  • Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) are measured.
  • Asthmatic patients typically present with a low FVC and an even lower FEV1, leading to an FEV1/FVC ratio below 75%.
• After initial PFTs, administering a Short Acting Beta Agonist (SABA) can help confirm asthma:
  • An increase in FEV1 by 12% or more after using SABA indicates reversible airway obstruction typical of asthma.
  • If the improvement is less than 12%, the condition is likely COPD.

Provocative Testing

• In asymptomatic patients, a Methacholine Challenge Test may be conducted:
  • Administering methacholine, a muscarinic agonist, induces bronchoconstriction.
  • A drop of 20% or more in FEV1 from baseline reinforces the asthma diagnosis.

Additional Diagnostic Tools

• Complete Blood Count (CBC) can show elevated eosinophil levels, supporting allergic respiratory condition diagnosis.
• Serology may reveal elevated IgE antibodies associated with allergic reactions.
• Chest X-ray is not diagnostic for asthma but may help rule out pneumonia or hyperinflation associated with asthma conditions.

Key Takeaways

• Key symptoms of asthma include cough, chest tightness, and wheezing, particularly upon expiration.
• Confirmatory tests (PFTs, response to SABA or methacholine) are critical for accurate diagnosis.
• Elevated eosinophils and IgE are relevant in understanding the allergic aspect of asthma.

Signs and Symptoms of Asthma

• Presence of a productive cough often indicates mucus in the bronchi.
• Chest tightness and dyspnea lead to shortness of breath, making it challenging for patients to complete sentences.
• In severe respiratory distress, accessory muscles like scalenes and sternocleidomastoid may be recruited for breathing.
• Percussion of the lungs can show hyperresonance due to trapped air, typical of obstructive lung diseases.
• Auscultation commonly reveals wheezing, especially during expiration, although wheezing alone does not confirm asthma.

Sputum Analysis

• Sputum from a productive cough can be analyzed for specific markers:
  • Curschmann spirals: Mucus casts formed from mucus accumulation and epithelial cells in bronchioles.
  • Charcot-Leyden crystals: Derived from eosinophils, indicating an allergic response within the respiratory system.

Diagnostic Protocols

• Pulmonary Function Tests (PFTs) are essential for asthma diagnosis:
  • Measurements of Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) are taken.
  • Asthmatic patients typically show low FVC and lower FEV1, resulting in an FEV1/FVC ratio below 75%.
• Administering a Short Acting Beta Agonist (SABA) after initial PFTs aids in diagnosis:
  • An increase in FEV1 of 12% or more post-SABA indicates reversible airway obstruction, characteristic of asthma.
  • An improvement of less than 12% suggests the condition might be Chronic Obstructive Pulmonary Disease (COPD).

Provocative Testing

• The Methacholine Challenge Test is used for asymptomatic individuals:
  • Methacholine, a muscarinic agonist, triggers bronchoconstriction when administered.
  • A decrease of 20% or more in FEV1 from baseline supports an asthma diagnosis.

Additional Diagnostic Tools

• A Complete Blood Count (CBC) may reveal elevated eosinophil levels, indicating an allergic respiratory condition.
• Serology tests can show increased levels of IgE antibodies, linked to allergic responses.
• While a Chest X-ray is not definitive for asthma diagnosis, it can help exclude other conditions like pneumonia and assess hyperinflation associated with asthma.

Key Takeaways

• Primary asthma symptoms include coughing, chest tightness, and wheezing, predominantly noted during expiration.
• Diagnostic tests such as PFTs and responses to SABA or methacholine are crucial for confirming asthma.
• Elevated eosinophil counts and IgE levels contribute to understanding asthma's allergic components.
