Table 2.

The data dead space $V_{D}$ , end-tidal ${CO}_{2}$ -fraction $F_{Et} C O_{2}$ , ${CO}_{2}$ production rate of the organism $\dot{V} C O_{2}$ , duration of inspiration : duration of expiration I : E-ratio, airway resistance R, static compliance C of the lungs and thorax close to the FRC within this table are derived from the literature (Galetke07; Long and Santhanam 2017; Butler et al. 1957; Guo et al. 2005; Huang et al. 2016; Levitzky et al. 2018; Pasquis et al. 1976; Boggs and Tenney 1984; Weingarten 1990; Lumb 2016b; Joehr 1993). The respiratory rate $F_{opt}$ of an adult human and a newborn baby weighing about 3.5 kg in the penultimate column is the solution of equation (29) using these data. For example the adult $F_{opt}$ gives $\frac{1}{8} (\sqrt{\frac{0.5}{0.5 + 1} \cdot \frac{1000 \cdot 60}{3 \cdot 100} \frac{16 \cdot 196.8}{160 \cdot 0.052} + \frac{0 . 5^{2}}{{(0.5 + 1)}^{2}} \cdot \frac{1000^{2} \cdot 60^{2}}{{(3 \cdot 100)}^{2}}} - \frac{0.5}{0.5 + 1} \cdot \frac{1000 \cdot 60}{3 \cdot 100}) \approx 13.2 [1/min]$ The Factor $1000 \cdot 60$ is the conversion coefficient from ml. to liter respectively sec. to min. The associated tidal volume $V_{T, o p t}$ in the last column follows from (22) and the product $F_{opt} {\cdot V}_{T, o p t}$ is then the related minute volume. The above data allow the calculation of the entire physical respiratory power (27) of the adult human (30.64 mW) and the human newborn (3.84 mW) as well
