Since drowning is one of, if not the most, way divers die, I thought people might want to read this article I came across. I think it belongs in this forum but if not, please feel free to delete or move it.
I think it's important to remind ourselves about the horrors of drowning and be more empathetic to the survivors of the victims. I learned a lot from this article and hope others will too.

ABSTRACT
Internationally, drowning is a leading cause of accidental death that features in many legal cases. In these cases, possible mitigations and the ‘pain and suffering’ in terms of the duration and subjective experience of drowning are often pivotal in determining levels of compensation and outcome. As a result, there is a requirement to understand the stages of the drowning process, and the duration and physiological and subjective responses associated with each stage. In this short review we focus on these issues.
The events that result in drowning can be divided into the following sequence: (i) struggle to keep the airway clear of the water, (ii) initial submersion and breath-holding, (iii) aspiration of water, (iv) unconsciousness, (v) cardio-respiratory arrest and (vi) death – inability to revive.
There are many high-quality reviews on the physiology and pathophysiology of drowning.<a href="The experience of drowning - PMC">3</a>–<a href="The experience of drowning - PMC">7</a> Likewise, drowning following longer term immersion or in diving scenarios, and the treatment of drowning, are dealt with elsewhere.<a href="The experience of drowning - PMC">8</a>,<a href="The experience of drowning - PMC">9</a> Discussion of these areas does not need to be repeated. Whilst much of this review is applicable to other scenarios, such as warm water, it focuses on the duration and subjective experience of drowning shortly after immersion in cold water (which we arbitrarily take to be water temperature of less than 15°C). Cold water is a common factor in drowning cases and can be a major determinant of outcome. <a href="The experience of drowning - PMC">10</a>
From a medico-legal perspective, the questions of ‘how long does it take to drown?’ and ‘what is the pain and suffering associated with drowning?’ are often critical for determining the outcome of drowning-related cases in the courts. This is the primary focus of this short review. However, it is also hoped that this review will also increase the potential to identify a drowning individual, and improve understanding of the impact of time to rescue on outcome.

Introduction
Drowning is defined as ‘the process of experiencing respiratory impairment from submersion/immersion in liquid’. <a href="The experience of drowning - PMC">1</a> It has three outcomes: nonfatal, nonfatal with injury or illness, or fatal: it causes approximately 1000 deaths a day worldwide and leaves many times that number with lifelong morbidity. <a href="The experience of drowning - PMC">2</a>The events that result in drowning can be divided into the following sequence: (i) struggle to keep the airway clear of the water, (ii) initial submersion and breath-holding, (iii) aspiration of water, (iv) unconsciousness, (v) cardio-respiratory arrest and (vi) death – inability to revive.
