The monitoring of expired gas has long been known to be an important indicator of the physiological health of experimental animals.

  • CO & O2 Monitoring improves surgical survivability
  • CO& O2 Monitoring validates respiratory status
  • Commonly used in hypoxia and control of breathing studies

CWE offers a range of gas analyzers for different respiratory physiology applications.

CapStar-100 End-tidal CO2 Monitor

CapStar-100 End-tidal CO2 Monitor

The CapStar-100 Carbon Dioxide Analyzer provides continuous measurement of expired CO2 over the range 0-10 percent and Respiratory Rate (RR). 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 End-tidal CO2 Monitor for mice, rats, and larger animals

microCapStar End-tidal CO2 Monitor for Mice

The microCapStar End-Tidal Carbon Dioxide Analyzer 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 O2 & CO2 Monitor

GEMINI O2 & CO2 Monitor

The GEMINI Respiration Monitor measures CO2, O2, and respiration rate of spontaneously breathing or ventilated animals. It provides breath-by-breath readings for end-tidal CO2 and O2, and instantaneous respiratory rate (breaths/minute). Adjustable alarms are provided to monitor CO2 and respiratory rate.

CWE Oxystar fast-response respiratory oxygen measurement

OxyStar Fast Response O2 Monitor

The OxyStar-100 is a fast-response, high accuracy oxygen analyzer for respiratory monitoring, hypoxic gas studies, or general laboratory use. It features a measurement range of 0 - 100% O2, with a resolution of 0.1%. Sample flow is adjustable over a 10 - 200ml/min range, making respiratory oxygen measurements possible on small as well as larger animals and human subjects.

Accurate oxygen consumption measurement for small animals

MM-100 Metabolic Monitor

The MM-100 Metabolic Monitor is a complete system for measuring oxygen consumption in the small animal. Using the latest technology in paramagnetic O2, infrared CO2, and thermal mass flowmeter analyzers, it automatically computes O2 consumption, CO2 production, and respiratory exchange ratios (RER).

MMX Series Metabolic Monitor Expanders for 1 to 16 animals

MMX Series Metabolic Monitor Expanders

The MM-100 Metabolic Monitor is a complete system for measuring oxygen consumption in the small animal. Using the latest technology in paramagnetic O2, infrared CO2, and thermal mass flowmeter analyzers, it automatically computes O2 consumption, CO2 production, and respiratory exchange ratios (RER).
