Submitted by PocketLab on Fri, 06/02/2017 - 16:53

Exploration

A spirometer is an apparatus often used in the medical field to find the cause of shortness of breath. A spirometer can rule out lung diseases like asthma, bronchitis, and emphysema. A spirometer can measure forced vital capacity. Forced vital capacity is the amount of air exhaled during a forced breath. Explore what factors affect forced vital capacity.

Objective

In this exploration, students will:
1. Build a PocketLab Spirometer and learn how to relate the barometer readings to a person’s forced vital capacity.
. Investigate what variables affect a person’s forced vital capacity
