The statistics worsen when rescues are made by bystanders. If lifeguards or paramedics are unable to be called, bystanders must rescue the drowning person. Alternatively, there are small floating robots that can reach the victim, as human rescue carries a risk for the rescuer, who could be drowned. Death of the would-be rescuer can happen because of the water conditions, the instinctive drowning response of the victim, the physical effort, and other problems. After reaching the victim, first contact made by the rescuer is important. A drowning person in distress is likely to cling to the rescuer in an attempt to stay above the water surface, which could submerge the rescuer in the process. To avoid this, it is recommended that the rescuer approaches the panicking person with a buoyant object or extending a hand, so the victim has something to grasp. It can even be appropriate to approach from behind, taking one of the victims arms, and pressing it against the victims back to restrict unnecessary movement. Communication is also important. If the victim clings to the rescuer, and the rescuer cannot control the situation, a possibility is to dive underwater (as drowning people tend to move in the opposite direction, seeking the water surface) and consider a different approach to help the drowning victim. It is possible that the victim has already sunk beneath the water surface. If this has happened, the rescue requires caution, as the victim could be conscious and cling to the rescuer underwater.
The rescuer must bring the victim to the surface by grabbing either (or both) of the victims arms and swimming upward, which may entice the victim to travel in the same direction, thus making the task easier, especially in the case of an unconscious victim. Should the victim be located in deeper waters (or simply complicates matters too much) the rescuer should dive, take the victim from behind, and ascend vertically to the water surface holding the victim. After a successful contact with the victim, any ballast (such as weight belt) should be discarded. Finally, the victim must be taken out of the water, which is achieved by a towing maneuver. This is commonly done placing the victim body in a face-up horizontal position, passing one hand under the victims armpit to then grab the jaw with it, and towing by swimming backwards. The victims mouth and nose must be kept above the water surface. If the person is cooperative, the towing may be done in a similar fashion with the hands going under the victims armpits. Other styles of towing are possible, but all of them keeping the victims mouth and nose above the water. Unconscious people may be pulled in an easier way: pulling on a wrist or on the shirt while they are in a face-up horizontal position.
