Quick Answer
Start rescue breathing for drowning incidents after ensuring a safe and clear airway, typically after 1-2 minutes of continuous CPR, or after the victim is brought to the surface and is showing signs of regaining consciousness.
Establishing a Safe Airway
When a victim is being rescued from a drowning incident, it’s crucial to ensure a clear airway before starting rescue breathing. Use the chin-tuck method to lift the chin and tilt the head back, followed by checking the mouth and throat for any obstructions. If the airway is clear, proceed with rescue breathing.
Rescue Breathing Technique
The American Heart Association recommends a ratio of 30 chest compressions to 2 rescue breaths for drowning victims. Each rescue breath should be delivered over 1 second and last 1 second, with a tidal volume of 500-600 milliliters. This technique helps maintain adequate ventilation and oxygenation.
Timing and Priority
Rescue breathing should be initiated after establishing a safe airway, typically after 1-2 minutes of continuous CPR. If the victim shows signs of regaining consciousness, such as coughing, gasping, or regaining muscle tone, rescue breathing can be stopped and replaced with supplemental oxygen if available. In all cases, the priority is to ensure a patent airway and restore spontaneous breathing.
