CCTV footage to see if any evidence could be provided. By the afternoon, Navalny's wife, Yulia, had reached the hospital from Moscow. She brought with her Navalny's personal doctor, Anastasia Vasilyeva. The authorities, however, initially refused to allow them into the room. They demanded proof in the form of a marriage certificate that Yulia was indeed his wife. A chartered plane paid for by Cinema for Peace Foundation was sent from Germany to evacuate Navalny from Omsk for treatment at the Charité in Berlin. Approximately 31 h after symptoms onset, a doctor from the German team got a brief access to Alexey Navalny, and recorded bradycardia, hypothermia (34·4°C), and wide pupils non-reactive to light. According to German doctors, Navalny was under sedation with propofol, and it was the only obvious drug given at that time. The doctors treating him in Omsk had initially declared he was too sick to be transported but later released him, and he arrived in Berlin on 22 August. Alexander Murakhovsky, the head doctor at the Omsk hospital, told the press conference on 24 August that they had saved his life and found no traces of any poison in his system; he also said the doctors at the hospital had not been under pressure on the part of Russian officials. The doctors treating him at the Charité announced later in the day that while the specific substance was not yet known, clinical findings indicated poisoning with a substance from the group of nerve agents known as cholinesterase inhibitors, and that they would be performing further tests to discover the exact substance. Evidence might come with the publication of the initiated laboratory testing. As of 2 September 2020, Navalny was in a medically-induced coma. German physicians said that if he recovered lasting effects could not be ruled out. Dr. Murakhovsky wrote a letter to the Charité, demanding that they show laboratory data about him being poisoned with a cholinesterase inhibitor, stating the doctors in his hospital found no such evidence. He stated that cholinesterase decrease may have happened either by intake of a compound or naturally, also publishing a purported independent analysis detecting no cholinesterase inhibitors. He confirmed giving him atropine, which is used to counteract certain nerve agents and pesticide poisoning, but claimed the reasons were unrelated to poisoning. On 7 September, doctors brought Navalny out of the medically-induced coma. In a press release, Charité said:
