What to Expect During Your Exam

Exam Overview

To document the current severity of your respiratory condition (asthma, COPD, or chronic bronchitis), establish or confirm its diagnosis, assess pulmonary function test results, and evaluate how your symptoms impact your daily functioning and ability to work.

What the examiner evaluates:

  • Current diagnosis and ICD code for claimed respiratory condition(s)
  • Pulmonary function test (PFT) results including FEV-1, FVC, FEV-1/FVC ratio, and DLCO
  • Frequency and severity of exacerbations or asthma attacks
  • Current medications including inhalational bronchodilators, anti-inflammatory inhalers, and systemic corticosteroids
  • Requirement for outpatient oxygen therapy
  • Episodes of acute respiratory failure or hospitalization
  • Presence of cor pulmonale, right ventricular hypertrophy, or pulmonary hypertension
  • Symptoms including productive cough, dyspnea, wheezing, hemoptysis, and chest tightness
  • Functional impact on occupational and daily activities
  • History of condition onset, course, and any in-service exposures
  • Nexus between current condition and military service

Pulmonary function tests (spirometry) will likely be performed at the same appointment or as a separate scheduled test. Bring your rescue inhaler and any maintenance inhalers to the exam. Do NOT use your short-acting bronchodilator within 4-6 hours of spirometry unless medically necessary - but always follow your doctor's guidance for safety first. The examiner will review your service treatment records, VA treatment records, and any private medical records submitted. Physical examination will include auscultation of the lungs, assessment of breathing effort, and observation for signs of accessory muscle use or barrel chest.

Typical duration: 20-45 minutes

FEV-1 (Forced Expiratory Volume in 1 Second)

The amount of air you can forcibly exhale in one second. Expressed as a percentage of your predicted normal value based on age, height, sex, and race. This is the single most important rating metric for asthma and COPD under 38 CFR 4.97.

What to expect:

You will be asked to take the deepest breath possible and then blow out as hard and fast as you can into a spirometry device. This will be repeated at least 3 times for reproducibility. Results are reported as both raw liters and percent predicted. Post-bronchodilator testing may also be performed.

Key thresholds:

  • FEV-1 less than 40% predicted — Supports 100% rating (DC 6602) or 100% rating (DC 6600)
  • FEV-1 40-55% predicted — Supports 60% rating
  • FEV-1 56-70% predicted — Supports 30% rating
  • FEV-1 71-80% predicted — Supports 10% rating
  • FEV-1 greater than 80% predicted — May result in 0% rating without other qualifying criteria

Tips:

  • Do not use short-acting bronchodilator (albuterol) 4-6 hours before testing unless medically necessary for safety
  • Avoid caffeine, heavy exercise, and smoking for several hours before the test
  • Give maximum effort on every blow - the test depends entirely on your best effort
  • If you feel the test was not done correctly or you were not allowed to give full effort, politely inform the examiner
  • Request that both pre- and post-bronchodilator results be recorded, as VA rates on the most favorable result
  • If you have a bad respiratory day (infection, high pollen, etc.), inform the examiner - this is your 'worst day' presentation

Pain considerations: If forceful exhalation causes chest pain, chest tightness, coughing spasms, or dizziness, immediately inform the examiner so it is documented in the DBQ.

FEV-1/FVC Ratio (Tiffeneau-Pinelli Index)

The ratio of FEV-1 to Forced Vital Capacity (total air exhaled). A low ratio indicates obstructive lung disease. Expressed as a percentage. An independent rating criterion separate from FEV-1 alone.

What to expect:

Calculated automatically from the same spirometry maneuver as FEV-1. No additional effort required. Results will show both FVC in liters and FEV-1/FVC ratio as a percentage.

Key thresholds:

  • FEV-1/FVC less than 40% — Supports 100% rating (DC 6602 or 6600)
  • FEV-1/FVC 40-55% — Supports 60% rating
  • FEV-1/FVC 56-70% — Supports 30% rating
  • FEV-1/FVC 71-80% — Supports 10% rating

Tips:

  • VA must use the most favorable test result among all qualifying criteria at each rating level
  • Even if FEV-1 alone does not qualify for a higher rating, the FEV-1/FVC ratio may independently qualify
  • Ensure the examiner records both metrics in the DBQ - omission of either is an error

Pain considerations: Alert the examiner if the forced exhalation causes bronchospasm or coughing fits that prevent a valid test - this itself is clinically significant and should be noted.

DLCO (SB) - Diffusion Capacity of the Lung for Carbon Monoxide, Single Breath Method

How efficiently your lungs transfer gas from inhaled air to the bloodstream. Particularly relevant for COPD (DC 6600) and emphysema. A low DLCO indicates loss of functional lung tissue or surface area.

What to expect:

You will inhale a small, safe amount of carbon monoxide gas, hold your breath for about 10 seconds, and then exhale. The test measures how much CO was absorbed. May be conducted separately from spirometry.

Key thresholds:

  • DLCO (SB) less than 40% predicted — Supports 100% rating under DC 6600 (Chronic Bronchitis/COPD)
  • DLCO (SB) 40-55% predicted — Supports 60% rating under DC 6600
  • DLCO (SB) 56-70% predicted — Supports 30% rating under DC 6600

Tips:

  • Particularly important for COPD/emphysema claims - ensure this test is ordered and results recorded
  • Do not smoke for at least 24 hours before this test as carboxyhemoglobin interferes with results
  • Report all respiratory symptoms you experience during and after the test

Pain considerations: Inform the examiner if breath-holding causes dizziness, lightheadedness, or significant discomfort - these are clinically relevant findings.

Exercise Capacity Testing (Maximum Oxygen Consumption, VO2 max)

Maximum oxygen consumption in ml/kg/min during exertion, with cardiac or respiratory limitation. Used specifically under DC 6600 for COPD/Chronic Bronchitis rating.

What to expect:

May involve a treadmill, stationary bicycle, or walking test with simultaneous monitoring of breathing and heart rate. Not always performed - the examiner must document why if not indicated.

Key thresholds:

  • Less than 15 ml/kg/min with cardiorespiratory limitation — Supports 100% rating under DC 6600
  • 15-20 ml/kg/min with cardiorespiratory limitation — Supports 60% rating under DC 6600

Tips:

  • If exercise testing was not performed, ask the examiner to document the clinical reason on the DBQ
  • Describe your real-world exercise intolerance vividly - how many steps before shortness of breath, inability to climb stairs, etc.
  • Functional reports (buddy statements, personal statements) about activity limitation complement this test

Pain considerations: If exertion causes chest pain, severe dyspnea, or you require stopping before completion, ensure this is fully documented as it demonstrates exercise intolerance independent of test thresholds.

How to Describe Your Symptoms

Dyspnea (Shortness of Breath)

How to describe:

Be specific about what activities trigger your shortness of breath and how it has changed over time. Use concrete functional benchmarks: 'I can only walk half a block before I need to stop,' or 'I cannot climb one flight of stairs without stopping to catch my breath.' Describe both your average day and your worst days.

Worst-day example:

“On my worst days, I become short of breath just getting up from the couch to walk to the bathroom - approximately 20 feet. I have to stop and lean against the wall to recover. I cannot carry groceries, mow the lawn, or walk my dog. I sometimes wake up at night unable to breathe and have to sit upright for 30 minutes before I can lie back down.”

What the examiner listens for:

Exertional vs. rest dyspnea, nocturnal symptoms, orthopnea (need to sit upright to breathe), activity limitations that map to functional impairment, frequency and duration of episodes.

Understatements to avoid:

Saying 'I get a little winded sometimes' when you mean you are significantly limited. Describing only your best days. Failing to mention nighttime symptoms or awakenings due to breathing difficulty.

Asthma Attacks / Exacerbations

How to describe:

Document the number of attacks or exacerbations in the past 12 months. Specify whether they required emergency room visits, hospitalizations, oral steroid bursts, or physician office visits. Describe triggers (exercise, cold air, allergens, smoke, occupational exposures). Include any attacks during military service.

Worst-day example:

“In the past year, I had 5 episodes where my rescue inhaler was not enough to control my symptoms. Three of those required me to go to the urgent care clinic for oral steroids and a breathing treatment. One required an ER visit. During each attack, I cannot speak in full sentences, my lips sometimes turn blue, and I feel like I am breathing through a straw.”

What the examiner listens for:

Frequency of attacks (more than one per week supports 100%), whether attacks result in respiratory failure, number of steroid bursts per year (3+ per year supports 60%), whether physician visits are monthly or more frequent.

Understatements to avoid:

Minimizing the severity of attacks. Forgetting to count urgent care or telehealth visits as physician care. Not mentioning ER visits or hospitalizations.

Medication Requirements

How to describe:

List every inhaler and oral medication you take for your respiratory condition. Be precise: name the drug, dose, frequency, and whether it is daily or as-needed. Distinguish between rescue inhalers (albuterol/SABA), maintenance inhalers (ICS, LABA, LAMA), oral bronchodilators, and oral or injectable corticosteroids (prednisone, methylprednisolone). Bring your actual medication bottles or a medication list.

Worst-day example:

“I take Symbicort 160/4.5 twice every day without fail. I also use my albuterol rescue inhaler at least once daily, and on bad days, 4 or more times. Three times this year my pulmonologist prescribed a 5-day course of prednisone 40mg because my symptoms were out of control. Without all of these medications, I cannot function.”

What the examiner listens for:

Daily vs. intermittent bronchodilator use (daily = 30%), daily inhalational anti-inflammatory medication (30%), systemic corticosteroid bursts (3+ per year = 60%), daily systemic high-dose steroids or immunosuppressants (100%).

Understatements to avoid:

Saying 'I just use an inhaler' without specifying frequency. Forgetting to mention oral steroid prescriptions received from urgent care or primary care. Failing to list all inhalers including maintenance medications.

Productive Cough and Sputum Production

How to describe:

For chronic bronchitis, describe the frequency, duration, and character of your cough. Note whether sputum is produced, its color (clear, yellow, green = purulent), and whether it is blood-tinged. Describe how long you have had a chronic cough (chronic bronchitis is defined as productive cough for 3+ months in 2+ consecutive years).

Worst-day example:

“I cough productively every morning for at least 30 to 45 minutes before I can clear enough mucus to breathe comfortably. The sputum is usually thick and yellowish-green. On bad days, I cough throughout the day and have sometimes coughed so hard I vomited or noticed streaks of blood in the mucus.”

What the examiner listens for:

Chronic productive cough consistent with chronic bronchitis diagnosis, frequency and character of sputum, presence of hemoptysis, whether cough disrupts sleep or daily activities.

Understatements to avoid:

Dismissing cough as 'just a cough.' Not mentioning blood-tinged sputum. Failing to describe how long the cough has persisted.

Functional Limitations and Daily Life Impact

How to describe:

Describe specific activities you can no longer do or that are severely limited because of your breathing condition. Include occupational impact (unable to work, had to change jobs, missed work days), social impact (avoiding activities that trigger symptoms), and personal care impact (difficulty showering, dressing, walking around the house).

Worst-day example:

“I had to leave my job as a construction foreman because I could not tolerate dust, fumes, or prolonged physical exertion. I now work a sedentary desk job but still miss approximately 2 days per month due to exacerbations. I cannot play with my grandchildren, walk more than one block, or attend outdoor events in cold weather. I sleep in a recliner because lying flat makes my breathing worse.”

What the examiner listens for:

Specific functional limitations that correlate with pulmonary impairment, occupational impact, social and recreational restrictions, whether the veteran can perform activities of daily living independently.

Understatements to avoid:

Saying 'I manage okay' when you have significantly modified your life around your breathing limitations. Not describing occupational restrictions or job changes related to the condition.

Wheezing, Chest Tightness, and Other Symptoms

How to describe:

Describe wheezing (audible whistling sound when breathing), chest tightness, chest pain with exertion, and any other symptoms. Note frequency, triggers, and duration. Include any symptoms that occur at rest versus only with exertion.

Worst-day example:

“My chest tightens every morning when I wake up, and I can hear myself wheezing without a stethoscope. During cold weather or when I am around any smoke or strong smells, the wheezing becomes so loud my family can hear it across the room. I experience chest pressure that I would describe as a 7/10 on bad days.”

What the examiner listens for:

Whether wheezing is present at rest or only with exertion, whether it is audible to others, presence of barrel chest or accessory muscle use on physical exam, cyanosis.

Understatements to avoid:

Not mentioning audible wheezing. Failing to describe chest pain or tightness that accompanies breathing difficulty.
