Final answer:
A person who slips underwater without struggle and doesn't resurface is likely drowning, which can be hard to recognize as the victim cannot shout or wave for help due to an involuntary airway seal. Early rescue and CPR are critical for survival, and there is still a possibility of recovery even if the victim appears unconscious, particularly in cold water scenarios.
Step-by-step explanation:
A person who slips underwater without a struggle and does not resurface is most likely experiencing drowning. Drowning is a deceptive and often silent event.
Contrary to popular belief, a drowning person is unlikely to shout for help due to the involuntary muscular spasm that seals the airway and prevents the passage of air and water.
The instinctive drowning response includes a low head position in the water, tilted back mouth open, and possibly uncontrolled arm and leg movements that are not visible above the water. Recognizing these signs is crucial for timely intervention and rescue.
There are several myths about drowning, including the mistaken idea that a person can vocalize distress when drowning or that it is too late to save someone who appears unconscious in the water.
In reality, immediate rescue and CPR can significantly increase the chance of survival, especially if the person has an airway still sealed by the larynx spasm, and there's no water in the lungs.
This is more effective and can lead to a full recovery, particularly in cases of cold water immersion, where even prolonged submersion does not always result in fatal outcomes.
