Any time someone has aspirated water there is a risk that the function of lungs has been compromised and a risk of infection from bacteria in the water. This is very difficult to determine as a lay first aider and via a visual analysis.
Medical assistance should always be sought after anyone has experienced any degree of drowning. PADI amended the terminology used when teaching EFR and Rescue Diver programs to reflect this.
Near Drowning is no longer used to reduce instances when a rescuer may assist someone that has aspirated water to any degree. They are now considered to have had a drowning incident and must seek medical assistance.
