Here's an example of what's due today

Spirometry lab

Tue, May 4, 2027 · Week 16 · Human Anatomy & Physiology (Human Body Systems)

Today's goal: Students will measure lung volumes with a spirometer and record oxygen saturation.

What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Spirometry data table

Completes: Completes the spirometry lab target: a data table of tidal volume, vital capacity, oxygen saturation, and resting heart rate with a predicted-versus-measured comparison.

I used the spirometer hygienically with a fresh disposable mouthpiece, measured each volume in three trials, and compared my results to the predicted values for my height, age, and sex. My SpO2 of 98% is in the normal 95 to 100% range.

Measure	Trial avg/best	Predicted	Notes
Tidal volume	0.5 L (avg of 3)	0.5 L	Normal, matches predicted
Vital capacity	4.2 L (best of 3)	4.4 L	Slightly below predicted
Oxygen saturation	98%	95-100%	Normal
Resting heart rate	70 bpm	60-100 bpm	Normal

Also due today: Submit your data table to the Schoology assignment for HBS Respiratory Day 3 (Lab).

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Evaluate Body SystemsSelf-check skill: Interpreting an oxygen-saturation reading against the normal range

During the spirometry lab a pulse oximeter reads an oxygen saturation (SpO2) of 88% on a resting student. How should this value be interpreted?
