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.

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.

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).
