Which of the following statements is false about Cuthbertson's metabolic ebb and flow responses to trauma? The "ebb" phase is associated with a decline in body temperature and oxygen consumption. The "flow" phase occurs after resuscitation from a state of shock. The "ebb" phase is aimed at reducing posttraumatic energy depletion. The "ebb" phase leads to activation of the innate immune system and induction of the hepatic acute-phase response. None 10. In which of the following conditions is oxygen therapy not useful?
