Q: Michael Schumacher remains in a critical condition in hospital as doctors revealed he would not have survived his skiing accident had he not been wearing a helmet. 
  
 The seven-time Formula One champion is in an induced coma in intensive care at the University Hospital of Grenoble after hitting his head on a rock in a crash in the resort of Meribel in the French Alps on Sunday. 
  
 Doctors treating the 44-year-old German described his injuries as life-threatening, though they said they could not speculate further on his prognosis. 
  
 Jean-François Payen, the chief anaesthetist at the Grenoble University Hospital Centre where Schumacher is being treated told a press conference: “It is too early, at this stage, to make a judgement about the future of Michael Schumacher. His situation is critical.” 
  
 But he said without his helmet he would already be dead. 
  
 “Given the violence of the shock, his helmet protected him in part,” he said. “Someone who hadn’t been wearing a helmet would not have got here.” 
  
 Doctors said the brain scan Schumacher underwent on his arrival at the hospital showed "a great number of lesions". 
  
 The former racing driver is receiving treatment to reduce the pressure on the brain. 
  
 Doctors said: "The brain scan showed some intracranial haematoma, but also some cerebral contusions and edema. We operated urgently to try and eliminate the haematoma. After the operation we saw that we had been able to eliminate the haematoma, but also sadly the appearance of various bilateral lesions and so therefore he was taken to intensive care to try to help him." 
  
 They added: "His condition is critical as far as cerebral care. All the recommended treatments have been introduced." 
  
 They said he had only been operated on once and a second operation was at the moment not looking necessary. 
  
 Schumacher’s wife, Corinna, and their two children, were at his bedside, doctors said. 
  
 Professor Gérard Saillant, one of France’s leading brain surgeons, who flew to Grenoble hours after the accident, said Schumacher’s fitness would aid his battle to survive. 
  
 “Someone of 70 is less likely to survive this sort of accident than someone who is 45, and someone like Michael who is in top condition is more likely to survive than someone else.” 
  
 Professor Saillant operated on Schumacher after the driver injured his leg in a crash in 1995, but he said he was at the hospital as a friend, not to supervise his treatment. 
  
 He said Schumacher's family were “worried like a wife, worried like children. We are all concerned”. 
  
 Tributes have been pouring in from fellow drivers and sports personalities. Among those seen arriving at the hospital this morning were Jean Todt, who was the chief executive of Ferrari when Schumacher raced for the Italian team, and Ross Brawn, who was his mentor at Ferrari. Mr Brawn is now in charge of the Mercedes team Schumacher joined when he resumed his career in 2010. He retired at the end of last year. 
  
 The French authorities are investigating the circumstances of the accident. 
  
 Schumacher was skiing at the Meribel resort with his 14-year-old son when the accident happened on Sunday morning. The teenager was unharmed. 
  
 Officials said the seven-time Formula One World Champion was off-piste, about 20 metres from a junction between a red and blue run, when emergency workers attended to him minutes after his fall. 
  
 Professor Payen said he was “extremely agitated” immediately after the accident, and his condition had “rapidly worsened.” 
  
 The motor racing legend is an expert skier who owns a chalet at Meribel and knows the slopes well. 
  
 The authorities have warned skiers not to venture off-piste because of a high risk of avalanches, which have caused six deaths in the French Alps since Christmas. ||||| GRENOBLE, France (AP) — Doctors treating Michael Schumacher refused Monday to predict an outcome for the seven-time Formula One champion, saying they were taking his critical head injury "hour by hour" following a skiing accident.

 Chief anesthesiologist Jean-Francois Payen told reporters that Schumacher was still in a medically induced coma and doctors were focusing only on his current condition. 
  
 "We cannot predict the future for Michael Schumacher," said Payen, who is also in charge of Grenoble University Hospital's intensive-care unit. 
  
 "He is in a critical state in terms of cerebral resuscitation," he added. "We are working hour by hour." 
  
 Schumacher, the most successful driver in Formula One history, arrived at the Grenoble hospital a day earlier already in a coma and immediately underwent brain surgery. 
  
 The German driver was skiing with his son Sunday morning in the French Alpine resort of Meribel when he fell and hit the right side of his head on a rock. He was wearing a helmet, but doctors said it was not enough to prevent a serious brain injury. 
  
 Gerard Saillant, a trauma surgeon who operated on Schumacher when he broke his leg in a 1999 race crash, was at the hospital as a visitor. He told reporters that Schumacher's age — he turns 45 on Jan. 3 — and his fitness should work in his favor. 
  
 But the Grenoble medical team was being very cautious about Schumacher's prognosis. Working to relieve the pressure on his brain, they lowered his body temperature to between 34 and 35 degrees Celsius (93.2 to 95 degrees Fahrenheit) as part of the medically induced coma. 
  
 The neurology team at Grenoble University Hospital is recognized as among the best in France and the hospital, in a city that is the gateway to the French Alps, sees a large number of skiing accidents every year. 
  
 Schumacher has been seriously hurt before. He broke his leg in a crash at the Silverstone race course in 1999. He also suffered serious neck and spine injuries after a motorcycling accident in February 2009 in Spain. 
  
 The area where Schumacher was skiing is part of a web of trails that slice down through a vast and, in parts, very steep snowfield. Although challenging, the snowfield is not extreme skiing. The runs are broad and neatly tended, and the ungroomed area in between, known as off-piste — where the resort said Schumacher was found — is free of trees. 
  
 The resort said Schumacher was conscious when first responders arrived, although agitated and in shock. But Payen said Monday that after the fall Schumacher was not in a "normal state of consciousness." He was not responding to questions and his limbs appeared to be moving involuntarily. 
  
 He was airlifted to a local hospital and then later brought to Grenoble. Doctors said that stopover was typical and did not affect his condition. 
  
 His wife and other family members were by his bedside. 
  
 "The family is not doing very well obviously. They are shocked," said his manager Sabine Kehm, who added that the family still appreciated the outpouring of support. 
  
 The French prosecutor in Albertville has opened an investigation into the accident, according to the Mountain Gendarmerie in Bourg-Saint-Maurice, which will participate in the probe. The goal is to determine the circumstances of the accident and what was responsible for it. 
  
 Formula One drivers and fans rushed to wish Schumacher a quick recovery. 
  
 "Like millions of Germans, the chancellor and members of the government were extremely dismayed when they heard about Michael Schumacher's serious skiing accident," German Chancellor Angela Merkel's spokesman, Steffen Seibert, said in Berlin. 
  
 Sebastian Vettel, for whom Schumacher was a boyhood idol, told German news agency dpa: "I am shocked and hope that he will get better as soon as possible." 
  
 Ferrari, which Schumacher raced for, expressed its concern in a statement. 
  
 "Everyone at Ferrari has been in a state of anxiety since hearing about Michael Schumacher's accident," it said, adding that company president, Luca di Montezemolo, and race team leader, Stefano Domenicali, were in contact with the family. 
  
 British former world racing champion Jenson Button said posted that his "thoughts are with Michael Schumacher at this tough time. ... Michael more than anyone has the strength to pull through this." 
  
 During his career, Schumacher won seven drivers' championships and 91 race wins. After initial success with the Benetton team, Schumacher moved to Ferrari and helped turn the Italian team into the sport's dominant force. After initially retiring in 2006, he made a comeback in 2010 and raced for three years with Mercedes.

A: 
Michael Schumacher remains in an artificial coma, with his body temp lowered to 93.2 to 95 degrees, after hitting his head on a rock while skiing in the French Alps yesterday—and doctors are refusing to predict any outcome for the seven-time Formula One champ, reports the AP. Says the chief anesthesiologist at the University Hospital of Grenoble, "It is too early, at this stage, to make a judgement about the future of Michael Schumacher. He is in a critical state in terms of cerebral resuscitation. We are working hour by hour." But what they did say is that there's no way Schumacher would be alive had he not been wearing a helmet. And a brain surgeon unrelated to his care (who had previously operated on the German driver) noted that if anyone stood a chance of surviving such an injury, it's Schumacher, reports the Telegraph. "Someone of 70 is less likely to survive this sort of accident than someone who is 45, and someone like Michael who is in top condition is more likely to survive than someone else." The anesthesiologist shared one more detail from the accident today, saying after the fall Schumacher wasn't in a "normal state of consciousness": He wasn't responding to questions and his limbs appeared to be moving involuntarily.
