which of the following could produce a decrease in aiveolar ventilation with no change in total ventilation?

a decreased functional residual capacity.
b decreased resp. rate & tidal volume.
c decreased resp rate & increased tidal volume.
d increased resp.rate & decreased tidal vol.
e increased resp.rate & tidal vol.






























d-increased resp rate &decreased tidal vol.
increased resp.rate -->increased dead space breathing.
