Respiration Rate
In this activity, students have direct experience with the light-dependent reactions of photosynthesis. Learn more
Spirometer
Provides the student with direct experience regarding the relationship of light intensity and the rate of oxygen production. Learn more
Respiration Rate
Provides excellent data before and after exercise
Respiration rate vs. time graph
Combining our Relative Pressure Sensor with a Respiration Belt, this sensor measures the change in pressure that occurs as the chest cavity expands and contracts during breathing. The Respiration Belt is wrapped around the chest, and the rubber bladder inside the belt is inflated using the attached squeeze bulb.
We provide a DataStudio Electronic Workbook for simple display of Respiration Rate on your computer.
Typical Applications
- Conduct comparisons before and after exercise -- measure resting rate and recover time
- Compare respiration rates of athletes and non-athletes
- Compare respiration rates between different populations: male/female, ages, heights, etc
- Study effect of caffeine on respiration rate
Here's What You Need:
- Relative Pressure Sensor (PS-2114)
- Respiration Belt (CI-9842)
- Xplorer GLX Graphing Datalogger (PS-2002)
(or alternate PASPORT interface -- see other options)
Spirometer Sensor (PS-2152)
Measure airflow, duration and lung volume
Digits display peak flow rate and vertical meter shows current flow rate.
Disposable mouthpiece clips in.
The Spirometer is designed to support both expiratory (breathing out) and inspiratory (breathing in) activities. Each Spirometer includes two medical-grade disposable mouthpieces, and replacement 10-packs are available.
Typical Applications
- Compare a student's airflow before and after exercise
- Investigate the lung volume of athletes vs. non-athletes
- Compare smokers versus non-smokers
- Conduct respiratory experiments
- Determine total lung capacity
