[Respiratory volumes during anaesthesia (author's transl)]

The respiratory minute volume was determined in 144 normal persons during anaesthesia i a semi-closed system. The measured volumes were related to the bodyweight of the individual person: Quotient Q = Minute volume (ml/min.) over Bodyweight (kilogramme). For adults Q was found to be clearly dependent on bodyweight and sex; extreme weight groups required correction by a factor q which differed for men and women. A table for the calculated minute volumes is available for routine purposes.
