  1. Drowning Z. Rozkydal

  2. Drowning Immersion into water or liquid Airways are filling with water or liquid Asphyxia- a person is unable to breathe Aspiration of water Laryngospasmus

  3. Wet drowning Water goes into the lungs Dry drowning Apnoe, then laryngospasm (in 30 %). - water does not go into the lungs

  4. Sweet water Water in lungs is hypotonic It is resorbed into circulation It increases volume of circulated blood - hypervolemia - haemolysis, high level of potassium - fibrilation of ventricles- cardiac arrest

  5. Sea water Water is hypertonic Water and plasmatic proteins go from blood into alveoli of the lungs - pulmonary oedema, atelectasis - respiratory failure and acidosis

  6. First aid Removal of casualty from the water Risk of regurgitation of stomach content into the airways - roll him onto his side to clear his airways Do primary survey- open his airways check his response Be sure there is not a injury of cervical spine If he is unconscious- give 5 initial rescue breaths Follow wit 30 chest compressions Continue CPR 30:2 Call the ambulance Monitor vital signs

  7. Drowning in a cold water Hypothermia – increases the chance for survival CPR should last longer Cover the casualty with warm blankets Some cases of drowning- in epilepsy after alcohol intake
