💡 Big idea: Spirometry translates the structural features of the respiratory system into measurable physiological data used to diagnose lung disease.

- • Pulmonologists use spirometry every day to diagnose asthma, COPD, and other lung diseases.
- • Today you will collect your own lung-volume data and compare it to predicted values based on your height and age.
- • Every measurement must include units; a number without units is scientifically meaningless.
- • You will leave with a complete data table ready for tomorrow's CER.
- 1Review safe and hygienic spirometer use.
- 2Measure tidal volume during normal breathing.
- 3Measure vital capacity with a full forced exhale.
- 4Record oxygen saturation with a pulse oximeter.
- 5Tabulate your volumes and compare to predicted values.
- • Tidal volume and vital capacity are both recorded.
- • Oxygen saturation is logged and compared to normal.
- • Tidal volume (TV) is approximately 0.5 L at rest; vital capacity (VC) varies by height, age, and sex.
- • Oxygen saturation (SpO2) of 95-100% is normal; below 90% indicates hypoxemia.
- • Spirometry is a diagnostic tool used to distinguish obstructive from restrictive lung diseases.

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete any spirometry lab check-in or data-entry prompt in Lesson 3.1 Cardiopulmonary Connection on myPLTW that accompanies today's lung-volume measurements.
Mark the lab check-in complete in myPLTW after submitting your spirometry data table.
Gas-exchange task is done; today the lab check-in should show complete alongside your data.

Resources & readings
Vetted readings and references for this unit. Use them to prepare, to catch up if you were absent, or to go deeper on today's target.
Lab & supplies
- • Use a fresh disposable mouthpiece; never share mouthpieces between students.
- • Inform the teacher before participating if you have asthma, a respiratory condition, or recent respiratory illness.
- • Do not force-exhale to the point of dizziness; stop and rest if you feel lightheaded.
- • Dispose of used mouthpieces in the designated waste container immediately after use.
- • Wash hands before and after handling shared equipment.
