Validation of the NTX Wireless Patient Monitoring System
A Validation of the NTX Wireless Patient Monitoring System in Combination With Novel Computer Interface to Generate Proactive Medical Responses to Patient Specific Events
  • Reduction in time to detection of Clinically Significant events
  • Reduction of time to Intervention during Clinically Significant events
  • Reduction in the number of admissions to Intensive Care
1200 patients will have wireless monitors attached to their arm. They will be randomized to have their vital signs filtered through software that generates alerts, or software that does not generate alerts. Low and high limit alarms will be set according to published guidelines and adjusted at will by the response team. If appropriate the Vanderbilt University Medical Center Rapid Response team will be initiated per Institutional Policy
Observational Model: Cohort
Time Perspective: Prospective

Post-op orthopedic and GI patients who will be admitted for a minimum of 24 hours to the Round Wing area of Vanderbilt University Medical Center.
  • Desaturation
  • Bradycardia
  • Tachycardia
  • Hypertension
  • Hypotension
Other: Rapid Response Team (NTX wireless monitoring system)
If the subject is experiencing a life threatening change in their vital signs, the Rapid Response Team will be initiated per VUMC protocol.
