Causes & Risk Factors
Several factors can contribute to Near Drowning (Submersion Injury with Survival).
Near drowning happens when someone's breathing is impaired by submersion in water or other liquid, but they survive the incident.
Near drowning happens when someone's breathing is impaired by submersion in water or other liquid, but they survive the incident. The fundamental cause is oxygen deprivation that occurs when water enters the airways or when someone holds their breath underwater for too long. During submersion, the body's natural response initially involves breath-holding and then involuntary gasping, which can lead to water entering the lungs.
The mechanism behind submersion injuries involves both the immediate effects of oxygen loss and the body's complex response to near-drowning.
The mechanism behind submersion injuries involves both the immediate effects of oxygen loss and the body's complex response to near-drowning. When water enters the lungs, it disrupts the normal gas exchange that keeps our blood oxygenated. Even small amounts of water can cause significant problems by washing away surfactant, the substance that helps keep lung air sacs open. This leads to collapsed air sacs and makes breathing difficult even after rescue.
Several factors influence the severity of a near-drowning incident.
Several factors influence the severity of a near-drowning incident. Cold water can actually provide some protection by slowing the body's metabolism and reducing oxygen needs, particularly in children. However, cold water also increases the risk of hypothermia and makes it harder for victims to swim to safety. The type of water matters too - saltwater pulls fluid from the bloodstream into the lungs, while freshwater gets absorbed into the bloodstream, both creating different challenges for the body's systems.
Risk Factors
- Children between ages 1-4 years
- Males, particularly teenagers and young adults
- Inability to swim or poor swimming skills
- Lack of proper adult supervision around water
- Alcohol or drug use near water
- Medical conditions like seizures or heart problems
- Unsecured pools or water features at home
- Participating in high-risk water activities
- Boating without proper safety equipment
- Living in areas with frequent flooding
Diagnosis
How healthcare professionals diagnose Near Drowning (Submersion Injury with Survival):
- 1
When someone arrives at the emergency department after a near-drowning incident, medical teams move quickly to assess their condition.
When someone arrives at the emergency department after a near-drowning incident, medical teams move quickly to assess their condition. The initial evaluation focuses on the person's breathing, oxygen levels, and overall neurological function. Doctors need to know key details: how long was the person underwater, what type of water was involved, was CPR performed, and what symptoms have developed since the rescue. This information helps guide immediate treatment decisions.

Several tests typically follow the initial assessment.
Several tests typically follow the initial assessment. Chest X-rays can reveal water in the lungs or signs of pneumonia developing. Blood tests measure oxygen and carbon dioxide levels, check for electrolyte imbalances, and assess overall organ function. An arterial blood gas test specifically measures how well the lungs are working. If there are concerns about brain function, doctors may order CT scans or other neurological tests to check for signs of oxygen deprivation injury.

The challenge in diagnosing submersion injuries lies in their unpredictable nature.
The challenge in diagnosing submersion injuries lies in their unpredictable nature. Some people seem fine initially but develop serious complications hours later - a phenomenon called secondary drowning. Others may have obvious breathing difficulties right away. Medical teams often recommend observation periods even for people who seem recovered, because lung problems can develop 4-6 hours after the incident. The diagnosis isn't just about the immediate injury, but anticipating and preventing delayed complications that could be life-threatening.
Complications
- The most serious immediate complication of near-drowning is acute lung injury, which can progress to acute respiratory distress syndrome (ARDS).
- This condition makes it extremely difficult for the lungs to provide adequate oxygen to the body and may require prolonged mechanical ventilation.
- Secondary infections, particularly pneumonia, can develop from water-related bacteria or from the lung injury itself, sometimes appearing days after the initial incident.
- Long-term complications primarily involve potential brain injury from oxygen deprivation during the submersion.
- The extent of neurological effects depends on how long the brain was without adequate oxygen.
- Some people recover completely, while others may experience memory problems, learning difficulties, or motor function issues.
- Children's developing brains may be more resilient in some ways but can also be more vulnerable to lasting effects.
- Early and intensive rehabilitation can help maximize recovery, though the timeline for improvement may extend months or even years after the incident.
Prevention
- Water safety education represents the most effective prevention strategy for near-drowning incidents.
- Learning to swim is fundamental, but it's equally important to understand water safety rules: never swim alone, always have adult supervision for children, and avoid alcohol around water.
- Installing proper barriers around pools and spas, including four-sided fencing with self-closing gates, can prevent unsupervised access by young children.
- Personal flotation devices save lives, especially for boating activities and when swimming in open water like lakes or oceans.
- Even strong swimmers can benefit from life jackets in challenging conditions.
- Teaching children to ask permission before going near water, even if they know how to swim, creates important safety habits.
- CPR training for family members and caregivers provides crucial skills for responding to water emergencies quickly.
- Home water safety extends beyond pools to include bathtubs, buckets, and even toilets for very young children.
- Constant supervision means staying within arm's reach of young children around any water, including during bath time.
- Technology can help too - pool alarms, door alarms, and wearable water safety devices add extra layers of protection, though they should supplement, not replace, proper supervision and barriers.
Immediate treatment for near-drowning focuses on restoring normal breathing and oxygen levels.
Immediate treatment for near-drowning focuses on restoring normal breathing and oxygen levels. In the emergency department, medical teams provide supplemental oxygen and may need to use mechanical ventilation if the person cannot breathe adequately on their own. The goal is to support the body while the lungs recover from the water exposure. For severe cases, advanced techniques like positive pressure ventilation help keep collapsed air sacs open and improve oxygen exchange.
Hospital care often involves intensive monitoring and supportive treatment.
Hospital care often involves intensive monitoring and supportive treatment. Patients may receive IV fluids carefully balanced to avoid worsening lung problems, antibiotics to prevent pneumonia, and medications to support blood pressure and heart function. If someone develops acute respiratory distress syndrome (ARDS) from the lung injury, treatment becomes more complex and may require specialized ventilation techniques. Medical teams also watch carefully for signs of brain injury from oxygen deprivation.
The length and intensity of treatment varies dramatically based on the severity of the incident.
The length and intensity of treatment varies dramatically based on the severity of the incident. Some people may be observed for several hours and then discharged home with instructions to watch for delayed symptoms. Others may need days or weeks of intensive care. Rehabilitation services, including physical therapy, occupational therapy, and speech therapy, may be necessary for those who experienced significant oxygen deprivation affecting brain function.
Recent advances in treatment include better understanding of lung-protective ventilation strategies and the use of extracorporeal membrane oxygenation (ECMO) for the most severe cases.

Research continues into medications that might protect the brain from oxygen deprivation injury, though most current treatments focus on supportive care while the body heals naturally.
Living With Near Drowning (Submersion Injury with Survival)
Recovery from a near-drowning incident varies greatly depending on the severity of the initial injury and any resulting complications. Many people recover completely within days or weeks, returning to normal activities with no lasting effects. For others, the journey involves ongoing medical care, rehabilitation therapies, and gradual return to previous function levels. Families often need support understanding what to expect and how to help their loved one through the recovery process.
