Software and Analysis

VitalSense Monitor

  • Activates the sensors
  • Tracks and records sensor data
  • Displays data in a convenient numeric table or as a trend graph
  • Functions as the computer interface
  • Stores data in a nonvolatile memory
  • Transfers data to PC
  • Continuously logs data
  • Monitors and tracks up to 10 sensors
  • Designed for research, clinical and ambulatory applications
After sensor activation, each sensor transmits its first value to the VitalSense Monitor within 15 seconds and then takes another reading every 15 seconds. Transmission to the monitor occurs four times a minute on a transmission schedule that is synchronized with the monitor.

The subject wears the monitor which is then able to receive the sensor transmissions. The monitor logs and displays the data.

 

Ingestible Capsule

  • Easily ingestible and disposable
  • Comparable in size to a vitamin or a large gel capsule
The monitor is used to activate the capsule sensor. The capsule is swallowed with liquid. Transmission begins 15 seconds after activation and then occurs four times per minute. The capsule easily travels and passes through the GI tract without affecting bodily functions. Transmit time varies with individual; 12-48 hours is typical.

Dermal Temperature Patch

This superior temperature measurement solution can assist investigative researchers in the measurement of peripheral temperature. When used in association with ingestible capsules and heart rate sensors, peripheral temperature may be compared with core body temperature, heart rate, and activity. Integration of these parameters is important for the evaluation and treatment of many indications.

  • Waterproof
  • Hypoallergenic adhesive
  • Smooth, comfortable and easy-to-use
  • Battery life of 10 days following activation
The monitor is used to activate the dermal temperature patch. The dermal temperature patch can be placed at many different locations on the body to record skin temperature. Multiple dermal patches can be monitored simultaneously.

 

XHR Heart Rate and Respiration Rate Sensor

The VitalSense-XHR sensor is an innovative, compact device that wirelessly transmits Heart Rate and Respiration Rate to the VitalSense telemetric physiological monitoring system. The monitor is used to activate the state-of-the-art XHR sensor enabling researchers to monitor heart rate and respiratory rate on ambulatory subjects. Data is transferred near real time to the monitor four times per minute.

  • Chest-worn, wireless physiological sensor that incorporates an ECG-signal processor
  • It attaches to two standard ECG pads
  • Accurate
  • Water-resistant
  • Lightweight
  • Comfortable

WelchAllyn_vs_XHR

XHR_RR

Heart rate is measured every 15 seconds by both the VitalSense-XHR
heart rate sensor and the Welch Allyn Electrocardiogram during treadmill exercise. There is a linear correlation between the two devices, R² = 0.97.
The XHR has fewer artifacts at peak treadmill exercise.

Respiratory rate is ECG derived. This demonstrates the relationship between
Electrocardiogram Derived Respiration (EDR) and respiration measured by a Respironics CPAP device during bicycle ergometry. There is significant correlation between the two methods, R² = 0.82.

 

Medic Mode

Medic Mode is a special function that enables the VitalSense monitor to detect and record signals from any VitalSense sensor that is within reception range. It displays and records sensor ID, time stamp and temperature value for each sensor transmission that is detected.

 

Software and Analysis

The VitalSense application program is simple-to-use software utility that communicates with the VitalSense Monitor via an RS-232 cable. With this link, a variety of functions can be accomplished:

  • Setup of the VitalSense Monitor
  • Setup and initialization of the sensors
  • Real-time temperature data monitoring
  • Retrieval of recorded data from the VitalSense Monitor

 

Recorded Data Analysis Example
The VitalSense application program automatically extracts your data to an Excel
file type for easy graphing and analysis. It can also be combined with other data, for a more complete analysis of your subjects.

Real-time Temperature Monitoring
Along with real-time monitoring of temperature data using the VitalSense Monitor, you can also monitor it on your PC. Just connect the Monitor to the PC and click the "Real-Time" button on the application program's front display.

PC Requirements

  • Operating System: Windows '98, ME, 2000, NT 4.0, and XP
  • Pentium II® Processor (266 MHz or higher)
  • 64 MB of RAMCD-ROM Drive
  • 9-pin or 25-pin RS-232 serial communications port
