Stage 1 of cold water immersion can trigger involuntary gasping, hyperventilation, panic, and vertigo. Proper ascent procedures are crucial to prevent decompression sickness, and timely CPR is essential for unconscious individuals in cold water.
Stage 1 of cold water immersion, which occurs in the initial 3-5 minutes, can result in involuntary gasping, hyperventilation, panic, and vertigo. This stage is marked by the body's immediate physiological responses to cold water exposure.
Divers must be cautious during ascent from depths to prevent decompression sickness (DCS) due to the changes in ambient pressure, which can lead to various symptoms, including paralysis and death. Proper ascent speeds and decompression stops are crucial to avoid this condition.
While rescuers should attempt resuscitation even after prolonged immersion in cold water, the likelihood of survival decreases as the brain goes without oxygen, demonstrating the critical importance of timely CPR in such situations.
