Anyway, the victim will require cardiopulmonary resuscitation (CPR) after that, as it has been described above, but only alternating the 30 compressions and the 2 rescue breaths. In unconscious victims of choking, the American Medical Association advocates sweeping the fingers across the back of the throat to attempt to dislodge airway obstructions. However, many modern protocols recommend against the use of the finger sweep. Red Cross procedures specifically direct rescuers not to perform a finger sweep unless an object can be clearly seen in the victim's mouth due to the risk of driving the obstruction deeper into the victim's airway. Other protocols suggest that if the patient is conscious they will be able to remove the foreign object themselves, or if they are unconscious, the rescuer should simply place them in the recovery position as this allows (to a certain extent) the drainage of fluids out of the mouth instead of down the trachea due to gravity. There is also a risk of causing further damage (for instance inducing vomiting) by using a finger sweep technique. There are no studies that have examined the usefulness of the finger sweep technique when there is no visible object in the airway. Recommendations for the use of the finger sweep have been based on anecdotal evidence. For babies (infants under 1 year old), the American Heart Association recommends to perform cycles of back blows (5 back slaps) followed by chest thrusts (5 chest compressions, that are adapted).In the back blows, it's recommended that, before applying them, the baby is slightly leaned upside-down, being supported by a forearm of the rescuer and its respective hand (the baby's head must be carefully held in this maneuver, usually from the jaw). To achieve this position, the rescuer can sit down on any seat with the baby, so the baby's body (supported by the forearm and hand of the rescuer) can be leaned along the rescuer's thighs. As an alternative to this (in case of the baby is too big or any other problem), the rescuer can sit on a bed or sofa, or even on the floor (when no seat is near), supporting on the lap the baby's body, to make the upside-down leaning from the lap, at the right or at the left. If the rescuer can not sit down, at least could try to do the maneuver low over a soft surface (to reduce a possible fall). In case of the previous options are not possible, but the rescuer is skillful enough, the rescuer can still kneel on a knee, and place the baby's body along the thigh that is higher (with the forearm still supporting between the thigh and the baby), so the baby can be leaned a bit moving forward that thigh.
