Multigas analysis
Comprehensive gas analysis
The Spacelabs Healthcare Multigas Module is a sidestream analyzer that simultaneously monitors gas concentrations and alerts clinical personnel when the concentration of anesthetic agents, oxygen (O22), carbon dioxide (CO2), or nitrous oxide (N2O) moves outside the defined limits. The anesthetic agent being administered is automatically identified.
- RELIABLE CO2 & multigas monitoring
- FAST and continuous monitoring of oxygen including fiO2
- AUTO agent identification
- Isoflurane
- Desflurane
- Sevoflurane
- Enflurane
- Halothane
Features
Measurement of Respiration Rate, Carbon, Dioxide,Oxygen, Nitrous Oxide, and Anesthetic Agents | Up to two agents may be simultaneously detected; inspired and expired values for halothane (HAL), isoflurane (ISO), enflurane (ENF), sevoflurane (SEV), desflurane (DES); inspired and expired values for N2O and O2; inspired CO2 (I CO2) and end tidal CO2 (EtCO2) |
Automatic Features | Identification of agents; pressure and temperature compensation |
Suspend Mode | Allows module to remain warmed up between cases while sampling is turned OFF |
MAC/AGEMAC Values | Automatic MAC value calculation and AGEMAC adjustment based on patient age and body temperature |
Paramagnetic Oxygen Sensor | Oxygen concentration is measured using a paramagnetic oxygen sensor |
Product Specifications
Oxygen FiO2 and ETCO2 are displayed after one breath and have a continuously updated breath average. ET will typically decrease below nominal value (ETnom) when respiration rate (RR) exceeds the RR threshold (RRth) according to the following formulas:
