How much air can our lungs contain with Cobra SMARTsense

Principle

The lung is an organ that serves to breathe out carbon dioxide (CO2) and absorb oxygen (O2). The lung is stretched by contractions of the diaphragm. This is how breathing air from the environment enters the lungs. When the diaphragm is released, the lung is contracted again and the air is exhaled passively.

In the following experiment, the lung volume, i.e. the amount of air that the lung can take in, is to be determined. A spirometer is used for these measurements. Spirometers are frequently used in medicine because they can be used to determine irregularities in lung function.

Benefits

• Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation of students by using the intuitive measureAPP.
• Increased media competence.
• Use of the same type of spirometer as in medical diagnostics
• disposable turbine eliminates the risk of infection
