Stochastic Modeling of Particle Deposition in Lungs of Cystic Fibrosis Patients

Table 1

Morphometric scaling factors (SF), breathing conditions, and tracheal mucus velocities (TMV) in the investigated age groups. Breathing data have been taken from the ICRP report vol. 66 [16] while tracheal mucus velocities have been calculated according to the allometric function proposed by Mauderly and Hahn [17]. Abbreviations: FRC: functional residual capacity, TV: tidal volume, BF: breathing frequency, T: length of 1 breath cycle.

	SF	FRC (mL)	TV (mL)	BF (min^-1)	T (s)	TMV (mm min^-1)
1 year	0.353	244	102	43.2	1.39	1.2
5 years	0.517	767	213	30.0	2.00	2.7
Adult	0.840	3,300	750	14.4	4.17	5.5
