I would most likely associate this with either pneumonia (acute) or if patient is older some form of COPD; possibly Chronic Bronchitis.
It is called THERAPEUTIC INDEX. Therapeutic index is the comparison of the amount of a particular drug that causes the desired therapeutic effects and the amount that causes toxicity. The index can be low or high. A drug with a low therapeutic index will require only a small increase in dose to produce toxic effects in users.
Nice shift is the change in behavioral or feeding patterns by two or more competing populations to reduce interspecific competition. Interspecific competition is a type of competition between organisms of different species. A niche is a full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions.

I think simple diffusion is a former of active transport
