What to Expect During Your Exam

Exam Overview

To document the current severity of your respiratory condition so that the VA rating system can assign an accurate disability percentage under 38 CFR 4.97. The examiner will assess pulmonary function test results, symptom frequency and severity, medication requirements, hospitalizations, and any complications in order to populate the Respiratory Conditions DBQ.

What the examiner evaluates:

  • Current diagnosis (asthma, COPD, chronic bronchitis, emphysema, or other respiratory condition)
  • Pulmonary function test (PFT) results including FEV-1, FVC, FEV-1/FVC ratio, and DLCO
  • Frequency and severity of exacerbations or attacks
  • Medication regimen including inhalational bronchodilators, inhalational anti-inflammatory agents, oral corticosteroids, and immunosuppressive medications
  • History of hospitalizations or emergency department visits for respiratory crises
  • Episodes of acute respiratory failure
  • Presence of cor pulmonale, right ventricular hypertrophy, or pulmonary hypertension
  • Requirement for outpatient supplemental oxygen therapy
  • Exercise capacity limitations
  • Associated symptoms such as productive cough, hemoptysis, dyspnea on exertion, wheezing, and fatigue
  • Impact of the condition on daily activities and employment
  • Relevant imaging findings (chest X-ray, CT, high-resolution CT)
  • Service connection nexus (onset, in-service event or exposure, continuity of symptomatology)

The exam will typically be conducted in a VA clinic or contracted QTC/LHI facility. A spirometry (PFT) test may be performed on-site or results from recent testing may be reviewed. Do not use a bronchodilator inhaler for at least 4-6 hours before the exam unless medically necessary, as the examiner may need pre-bronchodilator spirometry results. Bring all medications in their original containers. If your state permits recording, consider recording the exam for accuracy.

Typical duration: 20-45 minutes

FEV-1 (Forced Expiratory Volume in 1 Second) - % Predicted

The amount of air you can forcibly exhale in one second, expressed as a percentage of the normal predicted value for a person of your age, height, sex, and race. This is the single most important spirometry value for VA rating purposes.

What to expect:

You will be asked to take a deep breath and blow out as hard and fast as possible into a spirometer mouthpiece. This is typically repeated 3 times to get the best effort. The test may be performed before and after a bronchodilator (rescue inhaler). The technician will encourage maximum effort each time.

Key thresholds:

  • 71-80% predicted — 10% rating (asthma); lower end of 'mild' category for COPD/bronchitis
  • 56-70% predicted — 30% rating (asthma, DC 6602); moderate impairment for COPD/bronchitis
  • 40-55% predicted — 60% rating (asthma DC 6602; COPD DC 6604; bronchitis DC 6600)
  • Less than 40% predicted — 100% rating (asthma DC 6602; COPD DC 6604; bronchitis DC 6600)

Tips:

  • Give maximum effort on every breath - suboptimal effort can result in artificially low scores that may actually help rating-wise, but you must give honest effort as the technician checks for reproducibility.
  • If you are having a bad respiratory day on the day of the exam, that is significant - your worst-day performance is what matters most for rating purposes.
  • Make sure the examiner records both pre- and post-bronchodilator values; the VA rates based on the most favorable result for the veteran.
  • Ensure your full name, date of birth, height, and weight are accurately recorded as they affect predicted values.
  • Inform the examiner if you have a cold, upper respiratory infection, or significant flare-up on the day of testing, as this should be documented.

Pain considerations: Forceful exhalation can trigger coughing, bronchospasm, or significant shortness of breath. Inform the examiner immediately if you experience chest pain, severe dyspnea, or need to use your rescue inhaler during testing. These reactions should be documented as evidence of airway hyperreactivity.

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

The ratio of FEV-1 to Forced Vital Capacity (FVC), expressed as a percentage. A reduced ratio (below 70-80% depending on age) indicates obstructive lung disease. This ratio is an independent rating criterion - meeting the threshold in either FEV-1 % predicted OR FEV-1/FVC is sufficient to qualify at a given rating level.

What to expect:

Measured simultaneously during spirometry. The FVC is the total volume of air forcibly exhaled from maximum inhalation to complete exhalation. Both values are derived from the same blowing maneuver.

Key thresholds:

  • 71-80% — 10% (asthma); mild category for COPD/bronchitis
  • 56-70% — 30% (asthma DC 6602); moderate for COPD/bronchitis
  • 40-55% — 60% (asthma DC 6602; COPD DC 6604; bronchitis DC 6600)
  • Less than 40% — 100% (asthma DC 6602; COPD DC 6604; bronchitis DC 6600)

Tips:

  • If your FEV-1 % predicted is at a borderline level (e.g., 41%), the FEV-1/FVC ratio may independently qualify you for a higher rating - make sure the examiner documents both values.
  • Mixed obstructive-restrictive patterns may result in a normal ratio with reduced FVC - ensure the examiner notes all abnormal values.
  • COPD and chronic bronchitis are defined by persistent airflow obstruction, so the ratio is key diagnostic evidence.

Pain considerations: Same as FEV-1 testing - report any bronchospasm, wheezing, or distress immediately.

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

How efficiently your lungs transfer gas (specifically carbon monoxide as a surrogate for oxygen) from the air into the bloodstream. Reduced DLCO indicates impaired gas exchange, commonly seen in emphysema and interstitial lung disease. DLCO is an independent rating criterion for COPD (DC 6604) and chronic bronchitis (DC 6600).

What to expect:

You will inhale a dilute mixture of carbon monoxide and a tracer gas, hold your breath for approximately 10 seconds, then exhale. The expired gas is analyzed. This test requires good cooperation and breath-holding ability.

Key thresholds:

  • 56-70% predicted — 30% rating (COPD DC 6604; bronchitis DC 6600)
  • 40-55% predicted — 60% rating (COPD DC 6604; bronchitis DC 6600)
  • Less than 40% predicted — 100% rating (COPD DC 6604; bronchitis DC 6600)

Tips:

  • DLCO is particularly important in emphysema where spirometry alone may underestimate disability.
  • If spirometry is borderline (e.g., FEV-1 of 58%), a severely reduced DLCO can independently support a higher rating.
  • Ask your examiner whether DLCO testing will be performed. If it is not performed and you have documented emphysema or significant gas exchange issues, document this gap.

Pain considerations: Generally well-tolerated, but the 10-second breath hold can cause lightheadedness. Sit down immediately if you feel faint, and have your inhaler accessible.

Exercise Capacity Testing (VO2 Max / Maximum Oxygen Consumption)

Maximum oxygen consumption during exercise (ml/kg/min), reflecting cardiopulmonary reserve. This is an independent rating criterion for COPD (DC 6604) and chronic bronchitis (DC 6600) at the 60% and 100% rating levels.

What to expect:

If ordered, this typically involves walking on a treadmill or pedaling a stationary bicycle while oxygen consumption is measured. This test may not always be performed at a routine C&P exam.

Key thresholds:

  • 15-20 ml/kg/min (with cardiorespiratory limitation) — 60% rating (COPD DC 6604; bronchitis DC 6600)
  • Less than 15 ml/kg/min (with cardiac or respiratory limitation) — 100% rating (COPD DC 6604; bronchitis DC 6600)

Tips:

  • If exercise capacity testing is not performed and you have significant exertional limitation, clearly describe your functional limits to the examiner - how far you can walk, how many stairs you can climb, and what happens (dyspnea, coughing, stopping) when you reach your limit.
  • The VA rater will use the most favorable test result when multiple criteria are met.
  • Document any limitation of exertion in your daily activities even if formal testing is not done.

Pain considerations: This test can precipitate significant respiratory distress. Ensure the examiner is aware of the degree of your exertional limitation before testing. The test should be stopped immediately if you experience chest pain, severe dyspnea, or O2 desaturation.

Pulse Oximetry / Oxygen Saturation (SpO2)

The percentage of hemoglobin saturated with oxygen in peripheral blood, measured non-invasively. While not a standalone VA rating criterion, significant oxygen desaturation at rest or with exertion supports findings of severe disease and requirement for supplemental oxygen.

What to expect:

A clip-on sensor placed on your fingertip. May be measured at rest, during activity, and/or after exertion.

Key thresholds:

  • SpO2 < 88% at rest — Supports requirement for outpatient oxygen therapy, which is a 100% criterion for COPD/bronchitis
  • SpO2 < 90% with exertion — Supports severity documentation and possible oxygen therapy requirement

Tips:

  • If you use home supplemental oxygen, bring documentation from your prescribing physician and your oxygen concentrator prescription.
  • If you experience oxygen desaturation with minimal activity, describe this clearly: 'My oxygen drops when I walk to the bathroom.'
  • Cold hands can affect accuracy - warm your hands before testing.

Pain considerations: Non-invasive and painless. If you experience anxiety or breathlessness during measurement, inform the examiner.

How to Describe Your Symptoms

Dyspnea (Shortness of Breath)

How to describe:

Describe dyspnea in terms of specific activities that trigger it and how the severity has changed over time. Use concrete comparisons: 'I used to walk a mile without stopping; now I cannot walk from my bedroom to the bathroom without stopping to catch my breath.' Quantify distance, number of steps, or time before you must stop. Describe dyspnea at rest vs. with exertion separately.

Worst-day example:

“On my worst days, I wake up already feeling like I cannot get enough air. I cannot shower and get dressed without sitting down to rest in between. I cannot carry on a conversation without pausing to breathe. I feel like I am breathing through a wet towel. I have had to call 911 twice because I could not get my breathing under control even after multiple doses from my rescue inhaler.”

What the examiner listens for:

Specific triggering activities, functional limitations on daily tasks, frequency of severe dyspnea episodes, whether dyspnea is present at rest, nocturnal dyspnea, and orthopnea (needing to sit upright to breathe).

Understatements to avoid:

Do not say 'I get a little winded sometimes' if you mean you stop activity and must sit down. Do not say 'I manage okay' when you have reorganized your entire life to avoid exertion. Describe your worst days, not your best days.

Asthma or COPD Attacks / Exacerbations

How to describe:

Describe each type of attack: mild (managed at home with rescue inhaler), moderate (required a doctor visit, urgent care, or oral steroids), and severe (required emergency department visit or hospitalization). Provide approximate counts per year for each type. Describe what an attack feels like, how long it lasts, and how long recovery takes.

Worst-day example:

“Last year I had about 8 attacks that required oral prednisone, and I went to the emergency room 3 times. My worst attack lasted 4 hours and I was admitted to the hospital for 3 days on IV steroids and continuous nebulizer treatments. After a bad attack, it takes me 2-3 weeks to get back to my baseline - I am completely wiped out and cannot do basic activities.”

What the examiner listens for:

Frequency of exacerbations per year, severity (ER visits, hospitalizations, respiratory failure), triggers, duration of attacks, recovery time, and whether attacks are increasing in frequency or severity.

Understatements to avoid:

Do not minimize hospitalizations or ER visits. If you have been admitted to the ICU or required mechanical ventilation or BiPAP/CPAP for an attack, this is critical information that directly impacts the 100% rating criteria. Count every steroid burst - even a 5-day Medrol dose pack counts as a course of systemic corticosteroids.

Medication Requirements

How to describe:

List every respiratory medication - name, dose, frequency, and why it was prescribed. Distinguish between scheduled daily medications and rescue/as-needed medications. The type and intensity of medication regimen is a direct VA rating criterion. Daily inhalational bronchodilator therapy alone supports at least a 30% rating for asthma.

Worst-day example:

“I take fluticasone/salmeterol (Advair) 500/50 twice daily, tiotropium (Spiriva) once daily, and montelukast (Singulair) once daily every single day. I use albuterol rescue inhaler 3-4 times a day on bad days and at least once a day on good days. I have taken oral prednisone 4 times this year for flare-ups. My pulmonologist recently told me we are running out of options and discussed starting a biologic medication.”

What the examiner listens for:

Whether bronchodilators are daily (scheduled) or intermittent, whether the veteran uses inhalational anti-inflammatory medications, how many courses of oral/IV steroids per year, whether immunosuppressive medications are required, and whether outpatient oxygen has been prescribed.

Understatements to avoid:

Do not forget to mention combination inhalers like Advair, Symbicort, Trelegy, or Breo - each contains both a bronchodilator and an anti-inflammatory, potentially meeting two criteria simultaneously at the 30% level. Do not minimize steroid bursts as 'just a Z-pack' - a steroid taper counts as a course of systemic corticosteroids for rating purposes.

Productive Cough and Sputum Production

How to describe:

Describe frequency (daily, intermittent), character of sputum (clear, white, yellow, green, blood-tinged), volume, and any associated odor. Chronic productive cough is a hallmark of chronic bronchitis and bronchiectasis. Describe the frequency: morning cough, all-day cough, nocturnal cough.

Worst-day example:

“I cough every morning for 30-45 minutes before my airways clear enough to function. Throughout the day I cough up thick yellow or green mucus. About 4-5 times per year the sputum becomes foul-smelling and I need antibiotics - sometimes a full 6-week course. On my worst days I cough so hard I vomit or lose control of my bladder.”

What the examiner listens for:

Frequency and character of cough, sputum volume and color changes indicating infection, need for antibiotics, and whether cough significantly disrupts sleep or daily activities.

Understatements to avoid:

Do not forget to mention blood-tinged sputum (hemoptysis) if it has occurred - this is a separately documented DBQ finding. Do not omit recurrent antibiotic courses for respiratory infections, as these support higher severity ratings for bronchiectasis and bronchitis.

Fatigue and Functional Impact

How to describe:

Describe how respiratory symptoms cause fatigue separate from any other conditions. The effort required to breathe with obstructed airways is enormously energy-consuming. Describe how fatigue limits your ability to work, maintain a household, engage in social activities, or care for family members.

Worst-day example:

“By noon on most days I am so exhausted from the effort of breathing that I have to lie down. I cannot hold a full-time job because I cannot predict when a bad breathing day will force me to leave early or miss work entirely. I had to stop coaching my son's soccer team because I cannot stand and talk for more than 10-15 minutes without becoming winded and needing to sit down.”

What the examiner listens for:

Concrete examples of functional limitation, impact on employability, inability to perform specific tasks, and whether fatigue is directly attributable to respiratory effort rather than other conditions.

Understatements to avoid:

Do not separate respiratory fatigue from your overall functioning - the combined effect is what matters. Do not say 'I am tired sometimes' when you mean 'I am incapacitated for hours every day.'

Sleep Disruption and Nocturnal Symptoms

How to describe:

Describe nocturnal coughing, wheezing, or shortness of breath that wakes you at night, how many times per week, what you must do to manage (sit upright, use rescue inhaler, use nebulizer), and how long before you can return to sleep.

Worst-day example:

“I wake up 3-4 times per week coughing uncontrollably or unable to breathe. I keep a nebulizer at my bedside and use it at least once or twice a week in the middle of the night. I sleep propped up on 3 pillows because lying flat worsens my breathing. My wife sleeps in another room because my coughing and wheezing keep her awake.”

What the examiner listens for:

Nocturnal asthma or COPD as evidence of poor disease control, requirement for nighttime medication or positioning, and impact on sleep quality and daytime functioning.

Understatements to avoid:

Do not omit sleep disruption simply because you have adapted to it. Adapted functioning is not the same as normal functioning.

Your Rights During a C&P Exam

  • You have the right to an adequate, thorough, and fully articulated C&P examination. If the examination is inadequate (does not address all relevant factors, lacks rationale, or does not include required testing), you have the right to request a new examination.
  • You have the right to submit a private independent medical opinion (IMO) that contradicts or supplements the C&P examiner's findings. This evidence will be weighed by the VA rater.
  • You have the right to record your C&P examination in most states under one-party consent laws. Research your state's recording laws before the exam and inform the examiner you are recording if you choose to do so.
  • You have the right to request a copy of your completed C&P examination report at no charge through MyHealtheVet, eBenefits, or a written request to your regional VA office.
  • You have the right to appeal a rating decision through the Supplemental Claim lane (new and relevant evidence), Higher-Level Review lane (same evidence, different reviewer), or Board of Veterans' Appeals (BVA). You have one year from the date of the rating decision to select an appeal lane.
  • You have the right to free assistance from an accredited Veterans Service Organization (VSO), an accredited claims agent, or an accredited attorney in preparing and prosecuting your claim.
  • You have the right under 38 CFR 4.7 to receive the benefit of the doubt when there is an approximate balance of positive and negative evidence - you do not have to prove your claim beyond a reasonable doubt.
  • You have the right to a rating based on the most favorable test result when multiple test criteria (e.g., FEV-1 vs. FEV-1/FVC vs. DLCO) are evaluated - the examiner must apply whichever criterion results in the highest rating.
  • Under 38 CFR 4.96, certain co-existing respiratory conditions cannot be separately rated (e.g., asthma and COPD affecting the same lung function). However, you have the right to ensure the condition most favorable to you is used for rating purposes.
  • You have the right to submit lay statements (yours and from others who observe your daily functioning) as competent evidence of your symptoms and functional limitations.
  • If you believe your C&P examiner was biased, did not review your claims file, or conducted an inadequate examination, you have the right to raise these concerns in your appeal and request a new examination.
  • If your condition has worsened since your last rating, you have the right to file for an increased rating at any time based on new evidence of deterioration.
