Abstract
The general topic of this work is to detect potencial relationship between tiredness and respiratory parameters in view of its possible use for prediction of dangerous situations which may occur in a number of everyday human activities due to tiredness. The measurements performed and results obtained so far demonstrated that the rate of tiredness can be reliably found in an increased incidence of non-stationarities in an otherwise stable steady breathing of monitored persons.
However, this phenomenon has just an indicative character, exhibits also high inter- and intra-individual variability and is detectable in long-term observation only (>1 h).
