Welch Allyn Connex® Clinical Surveillance System

Hospitals around the world are trying to reduce cost and risk associated with pressure ulcers, patient falls, in-hospital cardiopulmonary arrests and prolonged stays. The Connex Clinical Surveillance System is designed to help clinicians detect early patient deterioration and thus potentially reduce adverse events for currently unmonitored beds—through an innovative non-contact monitoring system.







Proven to help staff improve care, hospitals can simultaneously increase patient satisfaction while lowering facility costs by continuously trending heart rate, respiratory rate, and body movement without ever touching the patient. 

Plus with higher patient loads, the Connex System helps you manage your hospital's care by delivering up-to-the-minute trended vital signs to mobile devices, hallway displays, and through emailed status reports.

Did You Know?

Know the facts about Connex Clinical Surveillance


With the average hospital stay costing over fifteen thousand dollars, just a 9% reduction in length of stay could equate to over two million dollars of savings—for a 200-bed facility.


Early detection of patient deterioration can help reduce the number of transfers from a medical/surgical floor to the ICU, when using the Connex system.  


Falls are a leading cause of hospital-acquired injury and frequently prolong or complicate hospital stays. Falls are also the most common adverse event reported in hospitals. In fact, based on publicly reported average rates, a typical 200-bed hospital can expect 27 falls per year.


Connex helps by:

  • Continuously monitoring a patient's movement
  • Providing six personalized levels of bed exit sensitivity
  • Helping keep the patient comfortable with complete freedom of movement


According to the Agency for Healthcare Research and Quality (AHRQ), up to 24% of hospital patients can have pressure ulcers—and patients with pressure ulcers are at up to six times higher mortality risk than those with intact skin.



  • Allows staff to program personalized patient-turn protocols
  • Can send timely turn reminders to clinicians' mobile devices
  • Provides documentation and verification of patient turns
  • Filters artifacts to prevent "alarm fatigue" and provides an extremely low overall alarm rate

What Is It?

The Connex Clinical Surveillance System empowers clinicians to continuously monitor patient vitals on all beds on medical/surgical floors to help decrease the rate of adverse events such as falls, pressure ulcers and patient deterioration. The system integrates with your current workflow, with minimal overhead and is compatible with most EMR systems to give you the patient information you need, when and where you need it.


Connex Vital Signs Monitor

Allows clinicians to customize for each patient to improve patient safety

  • Continuously view the patient's heart rate and respiration rate
  • Customize sensitivity level for fall risk patients
  • Program turn protocol for skin integrity risk patients
  • Integrates into your vital signs processes



EarlySense Contact-Free Sensors

Eliminates the need for leads or cuffs, improving patient comfort

Bed Sensor

  • Placed under the patient mattress, sensing begins automatically as soon as the patient enters the bed
  • Compatible with most bed and mattress types
  • Gives valuable time back to clinical staff, and allows for more face-to-face interaction with the patient



Connex Central Station

Displays real-time patient status for the whole unit, improving productivity and safety

  • Allows clinical staff to stay up-to-date on patient status from anywhere in the hospital
  • Provides alerts at the central station, and can transmit to handheld devices


How It Works

The Connex Clinical Surveillance System is a multi-parameter solution trending vital sign and motion information of your patients, including an adjustable six-level bed exit alarm and patient turn protocol verification. 

The contact-free bed sensor measures respiration rate, heart rate, and movement in patients without the need for lots of leads and wires. 

Trended vital signs, body motion data, and timely alerts help your clinicians track patients and thus deliver proactive care, potentially leading to better clinical outcomes including:


Reducing the number of hospital-acquired pressure ulcers


Preventing patient falls


Aiding timely intervention by
Rapid Response Teams


Patented Technology

The Connex System uses a unique piezo-electric sensing plate placed under the mattress so the patient remains comfortable and enjoys complete freedom of movement. There are minimal leads or cuffs. Using advanced signal processing algorithms developed from over one million patient monitoring hours, the EarlySense Embedded Algorithmic Engine converts the patient's cardioballistic effect, respiratory motion pattern and large body movements into vital signs and movement rate monitoring. 

The patent-pending sensor filters out artifacts for a low overall alarm rate to prevent "alarm fatigue." 

The monitoring information is transmitted and displayed automatically at the bedside, nurses' station and on additional displays in centralized areas. The data is also sent simultaneously to handheld devices to facilitate intervention of all relevant caregivers throughout the unit.


Pressure Ulcer Management Tools

The sensors and software can help your nurses better manage to your hospital's Safe Skin Protocols. Management tools allow nurses to quickly see:

  • Which patients are on turn protocol
  • Turns recorded by a nurse or PCA at the bedside monitor
  • Reported turns actually verified by the system


  • "Low movement" alerts help nurses identify patients with lower than expected self-movement who might benefit from turn protocols
  • "Patient movement" detection alerts nurses to patients with enough self-movement that may not require turn protocols, potentially saving your staff time
  • "Air mattress detected" alarms note usage of active mattresses on patients with turn protocol

Fall Risk Tools

The Connex System helps you manage patients at risk for falls by providing bed exit alerts with unique six-level sensitivity levels. And with bed and chair sensors, your patients can be monitored throughout their stay. The system provides reports that display valuable fall prevention information:

  • Which patients are on a fall prevention protocol and at what sensitivity level
  • Bed exit alert history
