Lungs are organs which enable carbon dioxide (CO2) to be exhaled and oxygen (O2) to be absorbed. Contraction of the diaphragm connected to the lungs causes them to stretch so that air is drawn into them from the surroundings. When the diaphragm subsequently relaxes, the lungs return to their original positions and air is passively breathed out.
In the following experiment, the lung volume, which is the volume of air which the lungs can take in, is to be determined. A spirometer is used for this measurement. Spirometers are frequently used by physicians to determine irregularities in the functioning of lungs.
- Uses the same spirometer design which is also used in medical diagnostics
- One-way turbine system avoids infections
- All methods used in medical diagnostics can be performed
- Takes advantage of modern wireless data acquisition technology
- Determine your tidal volume (TV)
- Determine your expiratory reserve volume (ERV)
- Determine your inspiratory reserve volume (IRV)
