Option a, if only, if only w, x and y are correct.
00:17
W, x and y are correct.
00:22
This is the correct answer for the given question because when john halves his tidal volume and doubles his respiratory rate, the following changes occur.
00:35
Statement w, alveolar ventilation is unchanged.
00:39
Alveolar ventilation refers to the amount of fresh air reaching the alveoli per minute.
00:46
In this case, since john is breathing in less air with each breathe but taking more breathes per minute, the overall alveolar ventilation remains unchanged.
01:00
Statement x, dead space is unchanged.
01:03
Dead space is the portion of the respiratory system where no gas exchange occurs...
