Patients who have a near-drowning event are still at risk for morbidity/mortality from delayed or secondary drowning hours to days later
The underlying pathophysiology is related to inflammation secondary to the aspiration of water into the lung, and the way that I remember the association between near-drowning and ARDS is that the inhaled water washes away the surfactant leading to ARDS, analogous to how preterm newborns can have neonatal respiratory distress syndrome due to low surfactant levels
azibirdFrom UTD: Children with nonfatal drowning, defined as a process resulting in primary respiratory impairment from submersion or immersion in a liquid medium, may have hypoxemia (due to fluid aspiration or reflex laryngospasm) resulting in noncardiogenic pulmonary edema and acute respiratory distress syndrome.+
