The first choice for on-site emergency treatment of drowning patients is artificial respiration

When a person is submerged in water, water and debris fill the respiratory tract and alveoli, causing hypoxia and suffocation, it is called drowning or drowning. The death caused by respiratory and cardiac arrest is called drowning.
The primary measure for the treatment of drowning patients is immediate mouth to mouth artificial respiration, and starting respiratory treatment immediately is positively correlated with survival.
Respiratory tubes, assistive buoyancy devices, and other devices can enable specially trained rescue personnel to complete treatment in deep water, but they can be safely used without delay due to the lack of such equipment. Untrained personnel are not allowed to use such equipment. The respiratory management of drowning patients is similar to that of any cardiac and respiratory arrest patient with potential trauma, and the respiratory management equipment of ordinary patients can be used.
Once the patient’s airway can be opened and the safety of the rescuer can be ensured, respiratory rescue should begin, which is usually completed when the patient is in shallow water or has moved out of the water. If rescue personnel in the water have difficulty holding the patient’s nostrils, supporting the head, or opening the airway, mouth to nose breathing can be used instead of mouth to mouth breathing.
It is not necessary to clear the aspiration of water in the airway. Some patients do not aspiration any water due to throat spasms or holding their breath, while most drowning patients only aspiration a small amount of water, and the water is quickly sucked into the circulation. It is unnecessary and dangerous to remove water from the airway by any method other than an attractor. For example, abdominal compression can cause reflux of gastric contents and secondary aspiration, and is associated with other injuries. Resuscitation of drowning patients should not be routinely performed using the Heimlich method.
The use of Heimler’s method delays early ventilation and leads to complications, and there is no basis for using Heimler’s method as the first step in resuscitation of drowning patients; The Heimlich method should only be used when there is suspicion of airway foreign body obstruction, but if there is suspicion of airway foreign body obstruction, chest compressions should be considered instead of the Heimlich method. Recent evidence has shown that chest compressions are superior to the Heimler method, as they can increase chest pressure and aid in the removal of foreign objects.
