Acute infections of the upper and lower respiratory tract caused by airborne pathogens
Conditions
Interventions
Group 1: 50 healthy probants are exercised on an ergometer. They wear different masks during the task. Particle emission is measured as particle concentration in a sealed measuring chamber.

| Measure | Time frame |
|---|---|
| The exposure lasts for 10 to 15 minutes for each mask type. During this time, a detectable concentration curve can be expected in the measuring chamber. The particle concentration is recorded using aerosol spectrometers. | — |
