[The regularity of the breathing pattern of both sitting and reclining adults is not different]. / Die Regelmäßigkeit der Ruheatmung sitzender und liegender Erwachsener unterscheidet sich nicht.

BACKGROUND: A prestimulatory regular breathing is required for the respiration-olfactometry. In a sitting position, just about every second prestimulatory breathing sequence fulfilled this requirement checking off -line. It should be examined whether breathing in reclining position is more regular. METHODS: The coefficients of variation of the time parameters of breathing in reclining and sitting position during 30 min were determined and compared. RESULTS: Breathing regularity did not increase in reclining position with 48 healthy persons (age group 1: 18 to 30 years, n = 24, 18 women; age group 2: > 55 years, n = 24, 13 women). The age and gender had no eff ect on the proportion of regular breathing. With 7 persons, the yield of 5 on each other following regular breaths was inadequate. Additionally one person excluded from our study was not able to breathe regularly without interruptions. CONCLUSION: The respiration-olfactometry cannot be performed in each person. It is not more successful in reclining than in sitting position.
