Respiratory Gas Monitoring for Small Animals

The monitoring of expired gas has long been known to be an important indicator or the physiological health of experimental animals. CWE Incorporated offers a range of gas analysers for different respiratory physiology applications.

  • For routine monitoring of CO2, the CapStar-100 End-Tidal CO2 Analyser is the most popular.
  • The new microCapStar is specifically designed for mice and other very small animals.
  • The GEMINI Respiratory Monitor features both CO2 and O2, as well as respiratory rate measurement.

CapStar-100 Carbon Dioxide Analyser:

Provides continuous measurement of expired CO2 over the range 0-10 percent. Its rapid response time, small sample flow requirements, and long-term stability make it ideal for respiratory gas measurement of rodents and larger animals.

MicroCapStar Co2 Analyser:

Provides accurate end-tidal or continuous measurement of expired CO2 in animals as small as mice. It features very low sample flow requirements, rapid response time, and long-term stability. Respiratory rate (RR) is computed using the excursions of the CO2 waveform. The CO2 and RR measurements, as well as a trend plot of the end-tidal values, are displayed on the graphics LCD screen.

Gemini Respiratory Monitor:

Accurately measures breath-by-breath O2 & CO2 concentration, it has long-term stability, linear output voltage, adjustable CO2 and respiratory rate alarms and is also suitable for rats & larger animals.

Applications and benefits:

  • use in conjunction with a CWE Ventilator
  • metabolic measurements (O2 consumption)
  • hypoxia and control-of-breathing studies
  • CO2 monitoring improves animal survivability
