As one of the oldest clinical indicators of disease in mammals, temperature is a crucial parameter to monitor, especially for infectious diseases where an acute fever is one of the first symptoms.
The easyTEL implanted telemetry system monitors and captures in real-time core body temperature and activity from small to large animals (80g to 10kg or more) such as Syrian Hamsters, Rats, Ferrets, Pigs, Dogs, or Primates. Temperature and activity are recorded continuously for up to 150 days in rodents and 285 days in large animals.
When fever or hypothermia is detected, the software can send an automated e-mail to a preset list of technicians or directors (for treatment or animal welfare euthanasia criteria), display a flashing warning on monitoring screens, and activate a sound alarm on monitoring computers. The analysis takes into account the expected fluctuations in temperature seen with circadian rhythms, derived from a baseline recording period.
In IOX2 acquisition software, onset of fever or hypothermia is detected if current temperature exceeds or decreases below a user-defined thereshold. The threshold can use the Standard Deviation or the raw temperature value as the criteria.
While this real-time analyzer is often used with temperature signals, it can be used with other physiological signals to monitor changes and trigger alerts.
