Myth: Drowning is noisy. I'll hear my child (or anyone) splashing and struggling in time to help. Fact: Despite what you may have seen in movies, in real life drowning is silent and can happen quickly. This is a particularly dangerous myth when it comes to young children.
Drowning is generally considered to be a 'silent death' for a person who is about to drown is unable to shout for help because he tries to save all his energy and the decreasing amount of oxygen in the lungs to keep his head above water. When water enters his air passage, he cannot shout anyway.
However, there is a consensus that someone can die from drowning within minutes of submerging. They're unlikely to survive within an hour, and within twelve hours, they will almost certainly die from their injuries.
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.
While distress and panic may sometimes take place beforehand, drowning itself is quick and often silent. A person close to the point of drowning is unable to keep their mouth above water long enough to breathe properly and is unable to shout.
Loss of consciousness comes quickly and the transition into the death state is more than likely similar to falling asleep. It takes less than 30-seconds for someone to drown. But panic is quickly replaced by what has been described as an amazing sense of peace and calm. Dr.
Watch for these signs of drowning: Head low in the water with mouth at water level. Head tilted back with mouth open. Eyes glassy and empty, unable to focus.
Within 3 minutes underwater, most people lose consciousness. Within 5 minutes underwater, the brain's oxygen supply begins to drop. A lack of oxygen can cause brain damage.
“Finally, the heart will slow down because it hasn't got any oxygen. Usually, they've been unconscious for three to five minutes in the water.” It takes an average of two minutes for someone drowning to become unconscious.
Near Drowning Survivors may Have Serious Brain Damage
Even if a near drowning victim is successfully revived, the interruption of oxygen to the brain may have enough to cause severe brain damage. Brain hypoxia is the name for a condition where the brain isn't getting enough oxygen.
The usual postmortem changes of vascular marbling, dark discoloration of skin and soft tissue, bloating, and putrefaction occur in the water as they do on land though at a different rate, particularly in cold water (4).
Saving someone who is drowning is more difficult and dangerous than many people think (heck, even realizing someone is drowning is hard — the signs don't look like you think they would.) A person who's drowning can be panicked and clutch, kick, and grab at you as you try to rescue them, dragging you both underwater.
When the body naturally tries to breathe for air underwater, inhaled fluid may act as an irritant inside the lungs. While a person might survive the initial drowning, unfortunately, it is common liquid has entered the lungs (pulmonary edema) and a person no longer has the ability to get enough oxygen to survive.
Heart disease is the number one silent killer disease.
The main risk factors that contribute to this increased risk include - Hypertension, smoking, sedentary lifestyle and raised cholesterol.
A lack of oxygen or chemical changes in the lungs may cause the heart to stop beating. This cardiac arrest stops the flow of blood and thus stops the transport of oxygen to the brain.
Thousands of people survive drowning with no complications and sometimes they may have various degrees of brain damage from oxygen deprivation. That's why immediate rescue breaths are so vital prior to giving CPR to drowning patients.
It is concluded that, in addition to the physical effort to keep the airway above the water, followed by the struggle to breath-hold, there is a period of pain, often described as a 'burning sensation' as water enters the lung. This sensation appears independent of the type of water (sea, pool, fresh).
Give five initial rescue breaths, and then continue with cycles of 30 compressions and two rescue breaths.
Autopsy findings:
May see bloody froth in the airway, water in the stomach, cerebral edema, petrous or mastoid hemorrhage. "Washerwoman" changes of the hands (shriveling of the skin) develop when submerged in water for several hours; occurs regardless of whether the person died in the water.
head tilted back with mouth open. eyes glassy and empty, unable to focus. eyes closed. hair over forehead or eyes.
97.5 The Unconscious but Breathing Victim
Placing the victim on the side in the recovery position helps to prevent these problems and allows fluid to drain easily from the mouth (Fig. 97.4). The person should be placed in a position that is horizontal and parallel to the shoreline if there is an incline.
The experience of drowning in the sea, swimming pool, fishing lake, river, agricultural pond, swamp, etc. can create a variety of post-traumatic stress scenarios for the drowned person, companions, and witnesses of the accident.
Children. Children ages 1–4 have the highest drowning rates. Most drownings in children 1–4 happen in swimming pools. Drowning can happen even when children are not expected to be near water, such as when they gain unsupervised access to pools.
* Do not attempt a rescue by jumping into the water. A distressed or panicked person or pet will always cause you to be in danger as they attempt to use you as a flotation device to save themselves.
