Poet® IQ Anesthetic Gas Analyzer

eQuality™ Patient Monitor


  • State-of-the-art non-dispersive infrared (NDIR) technology identifies and measures five anesthetic agent gases: Halothane, Enflurane, Isoflurane Desflurane and Sevoflurane.
  • Automatic or manual modes.
  • Breath-by-breath O2, CO2, and N2O monitoring.
  • Gas flow sampled at 100, 150 and 200 ml/min.
  • Optional printer, with user - definable report formats.
  • Mixed agent identification.
  • Fast warm-up time ensures full accuracy
    within minutes.
  • Auto-calibration.
  • Bright, real-time display of numerical values and waveforms provides instant notification of changing patient status.
  • Lightweight, portable design provides
    flexible workspace options.


Criticare’s Poet ® IQ Anesthetic Gas Analyzer, when paired with the nCompass™ Patient Monitor, provides a unique combination of leading edge vital signs technology and anesthesia gas monitoring in a compact, modular system.

A powerful combination—proprietary CSI vital signs and 5-agent gas analysis technology. Versatile, reliable, and incredibly compact. Designed for anesthesia applications in hospitals and outpatient surgical centers.

The Poet®IQ automatically identifies and quantifies inspired and expired O2, CO2, N2O, and five anesthetic agents. The system’s reliable performance, ease of use, flexible design, and affordable cost make it the ideal monitoring solution for anesthesia applications in hospitals and surgical centers.
