Key Features
- Investigates tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity.
- Can also measure oxygen consumption for metabolic studies.
- Simple lever control connects the subject to the atmosphere or to the float for recording.
- Fitted container for soda lime crystals to absorb carbon dioxide.
- Designed to offer minimum resistance to airflow, for greater comfort and more realistic results.
- Two 0.8 m corrugated breathing hoses with two mouthpieces and a nose clip.
Technical Specifications

| Control | Lever: atmosphere or float |
| Carbon dioxide absorber | Soda lime container fitted (crystals not supplied) |
| Recording | Needs a kymograph or datalogger system |
How It Is Used
The subject breathes through a mouthpiece, wearing the nose clip, and the lever is switched from atmosphere to the float when recording starts. Movements of the float follow each breath and are recorded on a kymograph or datalogger; with soda lime in the absorber, the steady fall of the float over time shows oxygen consumption.
Frequently Asked Questions
Are soda lime crystals supplied with the Spirometer?
No. The spirometer has a fitted container for soda lime crystals to absorb carbon dioxide, but the crystals are not supplied.
What is needed to record results from the Spirometer?
A kymograph or datalogger system is required to record results.
What can the Spirometer measure?
Tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity, and also oxygen consumption for metabolic studies.
