Interpretation

[2–4 sentence overall summary stating effort adequacy and main interpretive anchor]

Exercise Challenge/Hyperpnea Determination

(Include only if exercise challenge or hyperpnea surrogate was performed.)

• Result: [Positive for EIB / Negative for EIB by spirometric criteria]
• Quantitative basis: Maximum post-challenge FEV₁ fall [Value]% at [Timepoint]
• Severity: [Mild / Moderate / Severe per lab criteria] (State grading scale used if positive.)
• (If symptoms occurred with negative spirometry) Alternative considerations: [Exercise-induced laryngeal obstruction, deconditioning, dysfunctional breathing, cardiac limitation]. (Recommend targeted evaluation; do not diagnose from challenge alone.)

CPET Interpretation

(Include only if CPET was performed.)

• Functional Capacity: Peak VO₂ [Value] L/min ([Value] mL/kg/min, [Value]% predicted); Peak work [Value] W ([Value]% predicted). [Normal / Reduced]. (Qualify certainty based on effort adequacy.)
• Primary Physiologic Limitation(s): [Ventilatory mechanical limitation / Gas exchange limitation / Ventilatory inefficiency / Cardiovascular limitation / Chronotropic incompetence / Peripheral muscular limitation / Deconditioning pattern / Dysfunctional breathing]. (Justify with supporting variables. Do not label cardiac limitation without objective support.)
• Anaerobic Threshold: [Early / Normal / Late / Not determinable] at [Value]% predicted peak VO₂. (State method; if indeterminate, state why.)
• Safety Findings: ECG [normal / abnormal—specify]; BP response [normal / abnormal—specify]; SpO₂ [maintained / desaturation—specify nadir]. (Include urgent escalation if clinically significant arrhythmia, ischemia, or desaturation.)

Limitations

• [Factors affecting certainty: submaximal effort, early termination, equipment issues, missing measurements, medications, comorbidities]

Overall Confidence: [High / Moderate / Low] (Optional.)

Impression

• [EIB determination with quantitative criterion and severity if positive]
• [CPET functional capacity summary and principal limitation(s); desaturation status if measured]
• [Effort adequacy and impact on interpretation if relevant]

Recommendations

(Include only if findings warrant specific next steps; otherwise omit this section entirely.)

• (If EIB positive) [Pre-exercise SABA plan; controller therapy consideration; trigger mitigation strategies]
• (If EIB negative with persistent symptoms) [Targeted evaluation: laryngoscopy during exercise, CPET if not done, cardiac evaluation if indicated]
• (If CPET abnormal) [Next-step testing aligned to pattern: echocardiography, diffusion capacity, pulmonary vascular evaluation, rehabilitation program, etc.]
• Clinical management to be determined by the ordering clinician; findings above may guide next steps.
