Quality Assessment

(State whether overall test quality met acceptability and repeatability criteria. If suboptimal but interpretable, state confidence level.)

• Overall quality: [meets / partially meets / does not meet] acceptability and repeatability criteria
• Spirometry: FEV1 grade [grade], FVC grade [grade]; artifacts: [cough in first second / early termination / variable effort / none]
• Lung volumes: [number of acceptable maneuvers and technique limitations] (Include only if performed)

• Interpretation confidence: [high / moderate / low] — [brief rationale if not high]

Results

Spirometry - Pre-Bronchodilator

FEV1/FVC	[value]	[value]	[value]	[value]	[value]	—	—	ratio

Bronchodilator response: [Significant / Not significant] (Significant if Δ >10% of predicted for FEV1 or FVC; specify which parameter met criteria)

Lung Volumes

TLC	[value]	[value]	[value]	[value]	[value]	[value]	L
RV	[value]	[value]	[value]	[value]	[value]	[value]	L
FRC	[value]	[value]	[value]	[value]	[value]	[value]	L
RV/TLC	[value]	[value]	[value]	[value]	[value]	[value]	ratio

DLCO

(Include only if DLCO measured.)

Parameter	Measured	Predicted	LLN	z-score	% Predicted	Units
DLCO	[value]	[value]	[value]	[value]	[value]	mL/min/mmHg
VA	[value]	[value]	[value]	[value]	[value]	L
KCO (DLCO/VA)	[value]	[value]	[value]	[value]	[value]	mL/min/mmHg/L

Hemoglobin adjustment: [Adjusted using Hb = [value] / Hemoglobin not available; unadjusted DLCO reported]

Comparison to Prior Studies

(If no prior PFTs available, state "No prior PFTs available for comparison.")

• Prior test date(s): [date(s)]
• FEV1: [change value and %]; [exceeds / within] expected variability
• FVC: [change value and %]; [exceeds / within] expected variability
• FEV1/FVC: [change value]; [clinical significance comment]
• TLC: [change value and %]; [exceeds / within] expected variability (Include only if lung volumes performed)
• DLCO: [change value and %]; [exceeds / within] expected variability (Include only if DLCO performed)
• Reference equation change between studies: [yes, note limitation / no / not applicable]

Interpretation

(Begin by restating any quality limitations affecting interpretation certainty.)

Ventilatory Pattern

[normal / obstructive (FEV1/FVC below LLN) / restrictive (TLC below LLN) / mixed (FEV1/FVC and TLC below LLN) / non-specific pattern / possible restriction pending lung volume confirmation]

(Do not diagnose restriction from spirometry alone; if FVC is low with preserved ratio and lung volumes not measured, state that TLC is needed to confirm.)

Severity

(Omit if results normal. Grade obstruction by FEV1, restriction by TLC, diffusion impairment by DLCO. State classification system used.)

[Severity grading statement with classification system referenced]

Bronchodilator Response

(Include only if bronchodilator testing performed. Do not equate response with specific diagnosis.)

[Significant / Not significant] response; [parameter(s) meeting criteria]

Lung Volumes

(Include only if measured.)

[Comment on hyperinflation (increased TLC), air trapping (increased RV or RV/TLC), or features suggesting extrapulmonary restriction]

Gas Transfer

(Include only if measured.)

[Interpret DLCO with VA and KCO pattern; note if hemoglobin adjustment unavailable when clinically relevant]

Impression

• [Overall physiologic pattern and severity]
• [Bronchodilator response summary] (Include only if tested)
• [Key lung volume or diffusion findings] (Include only if measured)
• [Comparison to prior with clinically meaningful trends] (Include only if prior available)
• [Clinical correlation using cautious language: "compatible with" / "may be seen in" / "consider"] (Avoid definitive disease diagnosis without full clinical evaluation)

Recommendations

(Optional section; include only if part of service model. Keep test-focused: repeat testing intervals, additional PFT components, clinical correlation steps. Omit entirely if not applicable.)
