Causes & Risk Factors
Several factors can contribute to Drowning and Near-Drowning.
Drowning happens when water enters the airways and prevents normal breathing.
Drowning happens when water enters the airways and prevents normal breathing. When someone goes underwater, they initially hold their breath. As carbon dioxide builds up and oxygen decreases, the body's automatic response kicks in, forcing the person to try to breathe. Once water enters the lungs, it interferes with the exchange of oxygen and carbon dioxide, leading to hypoxia (lack of oxygen to vital organs).
In about 10-15% of drowning cases, the vocal cords spasm and close tightly when water touches them, preventing both air and water from entering the lungs.
In about 10-15% of drowning cases, the vocal cords spasm and close tightly when water touches them, preventing both air and water from entering the lungs. This condition, called laryngospasm or "dry drowning," can be just as dangerous because no oxygen reaches the lungs. The person may appear to have drowned without water in their lungs during autopsy.
Secondary drowning can occur hours after a water incident when small amounts of water in the lungs cause inflammation and fluid buildup, gradually impairing breathing.
Secondary drowning can occur hours after a water incident when small amounts of water in the lungs cause inflammation and fluid buildup, gradually impairing breathing. This delayed response affects fewer than 1% of drowning incidents but explains why medical evaluation is important even after seemingly minor water accidents. The key factor in all types of drowning is oxygen deprivation to the brain and other vital organs, which can cause permanent damage within 4-6 minutes.
Risk Factors
- Inability to swim or poor swimming skills
- Lack of supervision, especially for young children
- Alcohol or drug use near water
- Seizure disorders or medical conditions causing loss of consciousness
- Risk-taking behaviors like diving in shallow water
- Boating without life jackets
- Swimming in open water with strong currents or cold temperatures
- Bathing young children without constant supervision
- Access to water without barriers like pool fences
- Overestimating swimming abilities or water safety skills
Diagnosis
How healthcare professionals diagnose Drowning and Near-Drowning:
- 1
When someone is pulled from water, emergency responders focus immediately on assessing breathing, consciousness, and vital signs rather than formal diagnosis.
When someone is pulled from water, emergency responders focus immediately on assessing breathing, consciousness, and vital signs rather than formal diagnosis. The priority is restoring oxygen to the brain and organs. Paramedics check for pulse, breathing patterns, and neurological responses while beginning resuscitation efforts if needed.

Hospital evaluation includes chest X-rays to check for water in the lungs, blood tests to measure oxygen levels and electrolyte balance, and arterial blood gas analysis to assess how well the lungs are working.

Doctors also monitor for signs of hypothermia, which commonly accompanies drowning incidents and can actually be protective by slowing the body's metabolism and reducing oxygen needs.

Even if someone appears to recover quickly after a water incident, medical professionals recommend observation for at least 4-6 hours.
Even if someone appears to recover quickly after a water incident, medical professionals recommend observation for at least 4-6 hours. This allows monitoring for delayed complications like pulmonary edema (fluid in lungs) or secondary drowning symptoms. CT scans of the brain may be ordered if there are signs of neurological damage from oxygen deprivation. The medical team also assesses for other injuries that might have occurred during the incident, such as spinal trauma from diving.
Complications
- Brain injury from oxygen deprivation represents the most serious complication of near-drowning incidents.
- Even brief periods without oxygen can cause lasting neurological problems, including memory issues, difficulty concentrating, personality changes, or problems with coordination and movement.
- The severity depends largely on how long the brain was deprived of oxygen and how quickly effective resuscitation began.
- Lung complications can persist long after the initial incident.
- Pneumonia often develops from water or contaminants that entered the lungs during drowning.
- Some survivors experience ongoing breathing difficulties, reduced lung capacity, or increased susceptibility to respiratory infections.
- In severe cases, acute respiratory distress syndrome (ARDS) can develop, requiring extended mechanical ventilation and intensive care.
- Heart rhythm problems may also occur, particularly if the drowning involved cold water or prolonged oxygen deprivation.
Prevention
- Learn CPR and basic water rescue techniques
- Never swim alone or in unsupervised areas
- Avoid alcohol when swimming or supervising others near water
- Check water depth before diving and never dive in shallow water
- Swim in designated areas with lifeguards when possible
- Empty all containers with standing water after use
- Install door alarms and locks to prevent unsupervised water access
- Teach children to ask permission before going near water
Emergency treatment for drowning begins with immediate rescue from water and basic life support.
Emergency treatment for drowning begins with immediate rescue from water and basic life support. First responders start with the ABCs: Airway, Breathing, and Circulation. If the person isn't breathing, rescue breathing or CPR begins immediately. Every minute without oxygen increases the risk of brain damage, so speed is essential. Emergency medical services should be called even if the person seems to recover quickly.
Hospital treatment focuses on supporting breathing and organ function while the body recovers.
Hospital treatment focuses on supporting breathing and organ function while the body recovers. Patients often require supplemental oxygen or mechanical ventilation to ensure adequate oxygen reaches all organs. Warming procedures help treat hypothermia, which is common in drowning victims. IV fluids help maintain blood pressure and electrolyte balance, while medications may be given to prevent brain swelling or treat complications.
Neurological support becomes critical if brain injury from oxygen deprivation has occurred.
Neurological support becomes critical if brain injury from oxygen deprivation has occurred. This may include medications to reduce brain swelling, careful monitoring of intracranial pressure, and sometimes induced hypothermia to protect brain tissue. Patients with severe lung injury might need advanced ventilation techniques or extracorporeal membrane oxygenation (ECMO), which temporarily takes over the function of the lungs and sometimes the heart.
Recovery varies dramatically depending on how long the brain was without oxygen.
Recovery varies dramatically depending on how long the brain was without oxygen. Some people recover completely with no lasting effects, while others may face long-term neurological challenges. Physical therapy, occupational therapy, and speech therapy often play important roles in rehabilitation. New research into neuroprotective treatments offers hope for reducing brain injury in drowning survivors, though prevention remains far more effective than any treatment.
Living With Drowning and Near-Drowning
Recovering from a serious drowning incident often involves both physical and emotional healing. Many survivors experience anxiety around water, which is completely understandable and normal. Working with counselors experienced in trauma can help process the experience and gradually rebuild confidence. Family members, especially parents of child survivors, often struggle with guilt and fear, making support groups and counseling valuable for the entire family.
