You can potentially be revived after drowning for minutes, especially with immediate CPR and if the water is cold (which slows metabolism), but brain damage risk rises significantly after 4-10 minutes without oxygen, though rare successes occur even after 30-90 minutes in very cold water due to brain cooling. The best chance for good outcomes involves starting rescue breaths and CPR within minutes, ideally before 10-12 minutes, but any delay increases the chance of severe injury or death.
The brain cannot survive long without oxygen, and the continued lack of oxygen in the blood, combined with the cardiac arrest, will lead to the deterioration of brain cells, causing first brain damage and eventually brain death after six minutes from which recovery is generally considered impossible.
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.
Pulmonary oedema
In an attempt to protect the lungs, your child's body will send fluids into the lungs. This only worsens the condition and can lead to cardiac arrest or death. This condition can occur up to 3 days after the initial water incident.
Professional divers always practice and also take a deep breath before diving. By holding their breath, the divers can expel carbon dioxide out of their bodies when stay underwater. Almost all healthy adults easily hold their breath for one to two minutes.

Drowning is often silent
A drowning person cannot call for help, splash, or raise their arms. A drowning person remains upright in the water and may look like they are treading water with their arms, but their legs are usually not kicking. A drowning person is quiet. Children playing in the water make noise.
Yes, drowning is considered a traumatic death because it involves severe physical injury (respiratory trauma, lack of oxygen) and often results from accidental, forceful events, making it a leading cause of unintentional injury death, especially for children, and a significant source of PTSD for survivors and witnesses. Medical professionals often classify drowning victims as trauma patients due to the acute physiological damage and potential for associated physical injuries, such as spinal trauma from diving, says the National Institutes of Health (NIH) and Taber's Medical Dictionary.
Sudden (acute) pulmonary edema symptoms
Full recovery is possible if the oxygen supply was disrupted only briefly. Brain injury from prolonged ischemia can include swelling or seizures and can also lead to coma or death when severe.
If not rescued, all unresponsive drowning victims will die. If rescued, the unresponsive patient who still has a pulse (but is not breathing) has a reasonable chance for recovery if rescue breathing is begun immediately.
Look for these other signs of drowning when people are in the water: head low in the water, mouth at water level. head tilted back with mouth open. eyes glassy and empty, unable to focus.
Even a weighted body will normally float to the surface after three or four days, exposing it to sea birds and buffeting from the waves. Putrefaction and scavenging creatures will dismember the corpse in a week or two and the bones will sink to the seabed.
Hypoxia: With the interruption of breathing, the body experiences oxygen deprivation, leading to hypoxia, a condition where the tissues are starved of oxygen. Loss of Consciousness: Deprivation of oxygen to the brain results in a rapid loss of consciousness, often occurring within a few minutes of submersion.
What is nonfatal drowning? Drowning happens when a person is underwater and breathes water into the lungs. A drowning that doesn't result in death is often called a nonfatal drowning. When a person drowns, the airway (larynx) can spasm and close, or water can damage the lungs and keep them from taking in oxygen.
CPR with rescue breaths vital to resuscitation after drowning, new guidelines say. All people who are pulled from the water after drowning should receive CPR with rescue breaths and chest compressions, according to updated guidance from the American Heart Association and the American Academy of Pediatrics.
Symptoms of secondary drowning can develop within 1 to 24 hours after the incident. Although, secondary drowning may be a known term, it's actually a misnomer. There is no medical condition known as 'secondary drowning'.
People who experience pulmonary edema may struggle to breathe; the feeling has been described as being like drowning or suffocating. Some people cough up a thick, pink, frothy liquid while struggling for air. Pulmonary edema can be a life-threatening condition. Immediate medical attention is essential.
Arms up technique
If your child is gagging or choking on lumps in his meal or finger food quickly grab both his wrists and pull his arms straight up in the air while saying 'Arms up'. Your child will learn to do this if he is gagging or choking.
While all traumas leave a profound mark on an individual's life, there's a different level of difficulty in recovering from what's called "complex trauma." Unlike single-incident traumas, complex trauma stems from repeated experiences of stressful and traumatic events, usually in environments where there's no escape.
Profuse bleeding was reported in more than 40% of all drowning patient records.
It can be hard to explain what drowning feels like. People who've survived drowning have had unique experiences. But most people who aspirated (had water enter their lungs) used words like “painful” or “burning” to describe what they felt. Most people who didn't aspirate said they didn't feel any pain.
Carers are often concerned that death will be a painful experience for the person. However, the time before death is generally peaceful. There is a gentle winding down that may take several days. The body starts to 'let go' of life.
People survive heart attacks and strokes often, but occasionally they have complications. The same is true for drowning. Thousands of people survive drowning with no complications and sometimes they may have various degrees of brain damage from oxygen deprivation.
A drowning person's head will often be low in the water, with their mouth at water level. They may appear to be gasping or unable to keep their head above water. A drowning person may have glassy, unfocused, or empty eyes. They may also be unable to make eye contact.
