Unwiring the Patient
Depending on how many different vital signs require monitoring on a particular patient, a patient can end up confined to bed or severely movement-restricted simply because of all the wires attached to his or her body. For this reason, forward-thinking manufacturers of vital signs monitoring equipment are beginning to look at wireless sensors. Wireless sensors could save hospital staffs in surgery and recovery rooms from contending with numerous sensor wires. They could also enhance patient mobility and thus help speed recovery. A big step in the use of wireless sensors came with the approval of Bluetooth wireless technology in operating room equipment by the U.S. Food and Drug Administration (FDA) in 2003. Today wireless sensor deployment in hospitals is being enabled by technology advances and standards that address potential reliability concerns.
