A single CNS depressant by itself will not do this typically, because the rest of the neurological pathways in your brain not affected by the drug will still be functioning enough to keep up respiratory rate. However, when CNS depressants are mixed (more than one type of CNS depressant is taken), more areas of the brain have their activity inhibited, and the level of sedation compounds.

i would pop a gram of oxycodone right in front of you with confidence that it wouldn't kill me. Although, it would give me a very very bad time, and i'd likely be unconscious within 10 minutes and be shaking/twitching, perhaps even convulsing - I would still live through it.

So long as its only one CNS depressant in your system, the rule of thumb is that you'll be fine.

A major risk is that there are many over the counter medications, herbs, supplements, and thousands of other things which act as CNS depressants, and can kill a person when they're on an already high dose of a CNS depressant.
Some of these lesser known CNS depressants include things like valerian root in certain kinds of tea, allergy medications (anti-histamines), motion sickness pills (such as dramamine/dimenhydrinate, which is also an antihistamine), blood pressure medications (propranolol, a beta-blocker), and even anti-depressants and anxiolytics like zoloft, effexor, paxil, lexapro, yadda yadda yadda have affinity as an H-1 antagonist and cause sedations.

That's how a lot of celebrities die; they get prescribed so much shit and none of their doctors are really keeping an eye on it, and before they know it they've got 7-8 CNS depressants in their system, have a couple drinks, then pass out and die
alternatively you stop breathing and you die
