Waterboarding for dummies- Interrogators pumped detainees full of so much water that the CIA turned to a special saline solution to minimize the risk of death, the documents show. The agency used a gurney "specially designed" to tilt backwards at a perfect angle to maximize the water entering the prisoner's nose and mouth, intensifying the sense of choking and to be lifted upright quickly in the event that a prisoner stopped breathing. Interrogators were instructed to start pouring water right after a detainee exhaled, to ensure he inhaled water, not air, in his next breath. They could use their hands to "dam the runoff" and prevent water from spilling out of a detainee's mouth. They were allowed six separate 40-second "applications" of liquid in each two-hour session and could dump water over a detainee's nose and mouth for a total of 12 minutes a day. Finally, to keep detainees alive even if they inhaled their own vomit during a session a not-uncommon side effect of waterboarding the prisoners were kept on a liquid diet. The agency recommended Ensure Plus. These memos show the CIA went much further than that with terror suspects, using huge and dangerous quantities of liquid over long periods of time. The CIA's waterboarding was "different" from training for elite soldiers, according to the Justice Department document released last month. "The difference was in the manner in which the detainee's breathing was obstructed," the document notes. In soldier training, "The interrogator applies a small amount of water to the cloth (on a soldier's face) in a controlled manner," DOJ wrote. "By contrast, the agency interrogator ... continuously applied large volumes of water to a cloth that covered the detainee's mouth and nose."
One of the more interesting revelations in the documents is the use of a saline solution in waterboarding. Why? Because the CIA forced such massive quantities of water into the mouths and noses of detainees, prisoners inevitably swallowed huge amounts of liquid enough to conceivably kill them from hyponatremia, a rare but deadly condition in which ingesting enormous quantities of water results in a dangerously low concentration of sodium in the blood. Generally a concern only for marathon runners , who on extremely rare occasions drink that much water, hyponatremia could set in during a prolonged waterboarding session. A waterlogged, sodium-deprived prisoner might become confused and lethargic, slip into convulsions, enter a coma and die.
