hand capnometer

The ISA OR+ sidestream multigas analyser with the Masimo Root® patient monitoring and connectivity platform provides the following features and benefits:

  • > During general anaesthesia, the ISA OR+ monitors the inhaled and exhaled concentration of five anaesthetic gas agents (Sevoflurane, Isoflurane, Halothane, Desflurane, Enflurane), carbon dioxide (CO2), nitrous oxide (N2O), and oxygen (O2), in addition to respiration rate
  • > Requires only 50 ml sampling flow to support monitoring
  • > Time-saving in critical situations with virtually no warm-up time and full accuracy performance in less than 20 seconds
  • > Automatic anaesthetic agent identification
  • > Supports monitoring patients with high respiration rates, up to 150 bpm
  • > Low-power consumption and automatic temperature and pressure compensation
  • > Provides minimal alveolar concentration (MAC) calculated from the measured anaesthetic agents and N2O*
  • > Appropriate for monitoring adult, paediatric, or infant patients in a range of clinical
    environments including the operating theatre and intensive care unit
  • > Compatible with Masimo‚Äôs Nomoline Adapter and the Nomoline Airway Adapter Set to interface with endotracheal tubing
