That would work if you have excellent breath-holding ability. But since you're exerting yourself by carrying an ~150-lb body, there is a risk you'll pass out because you're holding your breath. So you probably should take multiple trips, repeatedly moving the person partially and then returning to get good air. You should _slowly_ exhale all the while.
DO NOT hyperventilate before holding your breath and exerting yourself! Reason is, if you hyperventilate, then take a big breath, hold it and exert yourself you are likely to pass out _instantly_ w/o warning! [This was something we learned as kids - do not do this! You _will_ pass out (and you also risk embolism/stroke).
- mrfusion 11y agoWhy slowly exhale? Why is hyperventilating first bad?
- simonswords82 11y agoI can take a guess on the exhale. If you're slowly exhaling there's less (no) chance you'll accidentally inhale.
- Dylan16807 11y agoIf you hyperventilate your body can't tell how much air you have left.
- giardini 11y ago"Why slowly exhale?" - So you don't increase the pressure in your lungs. "Why is hyperventilating first bad?" - Should you hyperventilate and then hold your breath and any pressure is put on your lungs, YOU WILL PASS OUT! Don't do this! Essentially hyperventilation reduces the blood's CO2 level. It becomes so low (while hyperventilating) that the body does not detect when the CO2 level subsequently rises to a dangerous level(while diving/holding your breath). The body fails to urge you to breathe fresh air and so you unwittingly pass out.

Deep-water divers hyperventilate and then take a big breath immediately before they dive. Sometimes "shallow water blackout" (same as what happens to kids in the "choking game) occurs, endangering the diver: https://en.wikipedia.org/wiki/Shallow_water_blackout https://en.wikipedia.org/wiki/Shallow_water_blackout
