Timely hands-only CPR improves the drowning patient’s autonomic circulation and maintains neurological function. Once the drowning patient has been rescued to shore, the patient’s condition should be assessed immediately, including state of consciousness, respiratory status and pulse. If the patient is not breathing and has no heartbeat, CPR needs to be started immediately, keeping the drowning patient in a relatively head-down position, with the aid of an oropharyngeal ventilator to prevent inadvertent aspiration and maintain a patent airway, or if conditions allow, early tracheal intubation, mask oxygenation and with AED defibrillation. Timely chest compressions to increase chest pressure and drain foreign bodies and fluid from the airway. After basic treatment, transport the patient as soon as possible and keep him warm to stabilise his vital signs.
