Information for Patients


People drown when they get too much water in their lungs. You can drown in as little as an inch or two of water. Babies can drown in a sink or bathtub. Preschoolers are most likely to drown in a swimming pool. People who have seizure disorders are also at risk in the water. Drowning can happen quickly and silently.

Drowning precautions should include

  • Fences around pools
  • Supervising children near any body of water, including tubs
  • Not swimming or boating when under the influence of alcohol or sedatives
  • Wearing life jackets when boating
  • Learning CPR
