Consecutive dives before flight

[inquis]

PPCO2 will be raising until it hits the plateau and PPO2 will be dropping.

So the fraction of N2 and therefore the partial pressure in the lungs at depth remains the same (or actually increases since the Respiratory Quotient is less than 1). In other words, on-gassing of inert gas.

Some studies also claim higher chance of pulmonary shunts and more N2 getting into the arteries.

Right, which would only *increase* the risk of DCS.

No.

There is no pressurized breathing gas.

The risk of decompression illness in breath-hold divers: a systematic review

Breath-hold (BH) diving has known risks, for example drowning, pulmonary oedema of immersion and barotrauma. There is also the risk of decompression illness (DCI) from decompression sickness (DCS) and/or arterial gas embolism (AGE). The first report ...
