If we take real numbers, the dead air space is 0.15l and normal breath is 0.5l, which makes 30% of the air we inhale is dead air. Am I correct?

first thank u for sharing that information with us , but i need to ask as a freediver we consider hyperventilation is no approach method of breathing cause it's like a shallow but fast breathing that actually lowers the co2 level and keeping the o2 gaz as it is and once you hold your breath u can stay longer holding your breath with no urge to breath but it can get you blackout because u get no contraction . So is it like the dead space situation or hyper-oxia?

Really good info but if you could speak up more into your mic that would be very useful
