A hospital patient has been arrested after she allegedly twice switched off the oxygen equipment on which a fellow patient depended because it was too noisy, German authorities have said.The public prosecutor’s office in the southwest German city of Mannheim obtained a warrant for the 72-year-old woman’s arrest and she was brought before the magistrate and investigating judge of Mannheim Local Court on Wednesday.The woman allegedly turned off the main switch of the oxygen equipment some time before 8:00 pm on Tuesday, “after feeling disturbed by the noise emanating from (it),” the statement said.“Although the suspect was informed by hospital staff that the oxygen supply was a vital measure, she allegedly turned off the device again at around 9:00 pm,” it continued.Oxygen equipment is used to ensure that enough oxygen reaches a patient’s cells and can take different forms, including a nasal cannula, face mask or tracheotomy tube, according to the Cleveland Clinic website."
