Wireless network in hospital monitors vital signs

A clinical warning system undergoing a feasibility study at Barnes-Jewish Hospital in St. Louis will include wireless sensors that take blood oxygenation and heart-rate readings from at-risk patients once or twice a minute. The data  and lab results in the electronic medical record will be continually scrutinized by a machine-learning algorithm looking for signs of clinical deterioration. If any such signs are found, the system will call a nurse on a cellphone, alerting the nurse to check on the patient.
