@virregribbe yes ur right, i thought he had said on 4:46 that all in is how much air someone can BREATH in...he meant how much air can someone get into his lungs, meaning total lung capacity.
i thought that ALL IN reffers to respiratory reserve volume
@Serpico261 Yeah I guess "How much air can you get out?" might be a bit confusing. . . Since ALL OUT refers to the volume that's left after ALL OUT aka RV.
Hi there, i am under the understanding that emphysema is an obstructive lung disorder, and i am wondering why u have classified it as a restrictive lung disorder? i enjoyed your video. Thanks.
@themuffler I will admit that I am no expert but my interpretation is that while emphysema is primarily obstructive (due to the destruction of airways), it is also restrictive in that the increased compliance of the lungs makes it difficult for the lung to decrease volume. If the lung cannot decrease volume, it cannot increase pressure to cause exhalation. Since restrictive disorders involve difficulty in changing lung volume, emphysema also has a restrictive component.
Not great for a visual learner (tough to watch) but the information is great and very accurate.

vitalapacity is the sum of all in and all out. you said accidentally its the difference

@Serpico261
Vital capacity is the the DIFFERENCE between ALL IN and ALL OUT. Not the sum.
TOTAL LUNG VOLUME (ALL IN) - RESIDUAL VOLUME (ALL OUT) = VC
TOTAL LUNG VOLUME (ALL IN) + RESIDUAL VOLUME (ALL OUT) = TLC + RV

@hennagerdj Actually restrictive pulmonary diseases decrease compliance since they increase the collagen content,lungs become ''stiff''

@themuffler I think it is classified as mixed. both obstructive and restrictive.
