MPPD entire lung alveolar region deposition fraction output for different breathing scenarios by particle size.

Breathing scenario	Particle size MMAD (GSD)

	0.9 μm (GSD 2.32)	2.1 μm (GSD 1.65)	3.6 μlm (GSD 1.32)	5.0 μm (GSD 2.1)
Tidal volume = 1607 ml, 17.5 breaths per minute

Oronasal (mouth breather)	0.1326	0.2036	0.2707	0.1551
Tidal volume = 1143 ml, 24.6 breaths per minute
Nasal or Oronasal (normal augmenter)	0.0701	0.0712	0.0612	0.0395
