Table 5.

Fundamental respiratory variables which Equations (29)–(31) are includes.

Variables (Unit)	Description	Equation	Equation Number
BR (1/min)	Number of breaths per minute.	$B R = \frac{n_{b r e a t h s}}{t_{i + n_{b r e a t h s}} - t_{i}} \times 60$	(29)
TV (mL)	Amount of air inspired in one respiratory cycle	$T V_{i} = V_{p e a k, i} - V_{t r o u g h, i}$	(30)
MV (L/min)	Amount of air inhaled within one minute	$M V = BR \times \bar{TV}$	(31)
