Study Notes
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.

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.
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.
