1. The respiratory quotient of resting and moving workers is about 1.

2. Unequal distribution of ventilation/perfusion ratio yields regional variation of the respiratory quotient.

3. Simultaneous observations on O2-consumption and CO2-production demonstrated that the respiratory quotient (R.

4. Initially, improvement of the respiratory quotient could only be achieved during prone positioning, from the 2nd day in the supine position as well.

5. Further, there is an overall increased metabolic efficiency (DeVivo et al., 1978; Bough et al., 2006), decreased respiratory quotient (Bough et al., 2000b), and maximal mitochondrial respiratory rate in rodents following the KD (Sullivan et al., 2004)

6. The endogenous loss of CO2 by agglutination to pyro-racemic acid and formation of oxalic acetate must, however, in the same way decrease the respiratory quotient (RQ), and even causes by taking away the bicarbonate from the „buffersystem” NaHCO3/CO2 the preponderance of the bicarbonate, to alcalosis.
