Physiological values of human respiration parameters.

Trait	Value for an Adult	Value for a Child
Respiratory rate (f)	12–20 /min	14–24 /min
Total Lung Capacity (TLC)	3.2–6,0 L	depends on age
Tidal Volume (TV)	0.5 L or 7–8 mL/kg bw *	7–8 mL/kg bw *
Vital capacity (VC)	4.5–5.0 L	depends on age
Functional Residual Capacity (FRC)	2.5–3.0 L	depends on age
Residual volume (RV)	1.2 L	0.5–0,8 L
Forced expiratory volume in 1st sec. (FEV1)	75% VC	75% VC

* bw—body weight.
