Drowning can also happen in ways that are less well known: Ascent blackoutalso called deep water blackout — caused by latent hypoxia during ascent from depth, where the partial pressure of oxygen in the lungs under pressure at the bottom of a deep free-dive is adequate to support consciousness but drops below the blackout threshold as the water pressure decreases on the ascent.

It usually strikes upon arriving near the surface as the pressure approaches normal atmospheric pressure. The primary urge to breathe is triggered by rising carbon dioxide CO2 levels in the bloodstream.

There is no bodily sensation that warns a diver of an impending blackout, and victims often capable swimmers swimming under the surface in shallow water become unconscious and drown quietly without alerting anyone to the fact that there is a problem; they are typically found on the bottom.

Further complications following the drowning incident — Inhaled fluid can act as an irritant inside the lungs.
