Spirometry data CER analysis
Students will analyze spirometry data and write a CER about respiratory function.
Written CER analyzing spirometry data: claim about respiratory capacity, two specific measurement evidence entries compared to predicted values, reasoning linking alveolar structure to capacity, and one factor affecting vital capacity.

- CER:
- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.

💡 Big idea: Comparing measured lung volumes to predicted values reveals whether the respiratory system is functioning within a healthy range.
- 0-10Review predicted reference ranges; annotate your data table with above/below status
- 10-25Identify the most meaningful comparison in your data; decide on a specific claim
- 25-45Write full CER: claim, two measured-value evidence entries, reasoning linking structure to capacity
- 45-58Add one factor that could affect vital capacity and explain the mechanism
- 58-70Peer review: check that reasoning names an alveolar or airway mechanism
- 70-80Revise and submit CER
- • Your spirometry data from yesterday is more than just numbers; it tells a physiological story.
- • Today you will analyze that story using the CER format, as a respiratory therapist would.
- • Comparing your values to predicted ranges is how clinicians identify patients who need further testing.
- • A complete CER with mechanistic reasoning is the highest-level thinking skill in this unit.
- 1Compare your lung volumes to predicted ranges.
- 2Make a claim about your respiratory capacity.
- 3Cite two measurements as evidence.
- 4Add reasoning linking alveolar surface area to capacity.
- 5Note one factor that could affect vital capacity.
- • CER includes claim, evidence, and reasoning.
- • Data is compared to predicted reference values.
- • A measured vital capacity significantly below predicted may suggest restrictive or obstructive lung disease.
- • Factors that reduce vital capacity include height, age, smoking history, and chronic lung conditions.
- • CER reasoning must connect the measured deviation (or match) to the underlying alveolar or airway mechanism.

Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete the spirometry data-analysis or CER reflection prompt in Lesson 3.1 Cardiopulmonary Connection on myPLTW; finish it before peer review of your CER.
Mark the analysis task complete in myPLTW after submitting your respiratory CER.
Lab task is done; today the analysis task should show complete and your CER should be submitted.
