麻醉气体监测

Anesthesia Monitoring

Anesthesia agent monitoring identifies and quantifies the anesthesia. This is done by using infrared absorption techniques to control the phases of the anesthesia. Therefore several gases have to be measured at once – online, accurately and reliably.

 

 

Targeted gases are Halotane, Isoflurane, Enflurane, Sevofluorane, Desflurane, CO2, N2O.

The trend to miniaturize such modules showcases the advantages of the Axetris MEMS-based broadband infrared source for NDIR gas detection.

 

Advantages of Axetris Infrared Sources :

  • True black body radiation (2 to 14 μm) for all gases
  • High emissivity
  • Small size
  • Fast electrical modulation (no chopper wheel needed) 
  • High modulation depth 
  • Low power consumption 
  • Long lifetime

Axetris offers solutions by providing a portfolio of IR sources with several reflector with or without integrated windows (BaF2, CaF2, GeART100).

Capnography

Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO2) in the respiratory gases. The CO2 concentration during a single breath is measured in a high temporal resolution to monitor the condition of the lungs. Initially used in hospital surveillance and emergency care, capnography is on the way to becoming popular in home care medicine. The trend to miniaturize such modules showcases the advantages of the Axetris MEMS-based broadband infrared (IR) sources for nondispersive infrared detector (NDIR) gas detection.

 

Advantages of Axetris Infrared Sources:

  • High emission at 4.26μm
  • Small size
  • Fast electrical modulation (Modulation frequency: >10Hz)
  • High modulation depth 
  • Low power consumption 
  • Long lifetime

Blood Gas Analysis

Blood gas analysis is an important medical diagnostic tool, where partial pressures of CO2 (pCO2) and O2 (pO2) are typically measured.

 

A number of non-invasive techniques for blood gas analysis have been recently developed. One such important non-invasive technique is transcutaneous (tc) blood gas analysis, where the partial pressures of these gases are measured across the surface of the skin. Transcutaneous blood gas analysis is fast becoming a popular technique, especially for use in neonatal monitoring, where invasive blood gas monitoring cannot be used.

 

Axetris IR sources are well-suited for use in tc blood gas monitors based on NDIR measurement with key advantages such as very small size, low thermal mass, high electrical input to optical output efficiency and stable emission characteristics. 

 

Advantages of Axetris Infrared Sources :

  • High emission at 4.26μm
  • Small size
  • Fast electrical modulation (Modulation frequency: >10Hz)
  • High modulation depth 
  • Low power consumption 
  • Long lifetime 

Axetris offers solutions by providing a portfolio of IR sources with several reflector with or without integrated windows (BaF2, CaF2, GeART100).

Pulmonary Diagnostics

NDIR is a well-accepted technique to measure and monitor various gases related to pulmonary function tests (PFTs). Various such techniques, which are related to spirometry, have been developed in the last decade, where a quick and precise monitoring of certain gases is necessary. Typical gases are CO and CO2, but also methane (CH4) and various nitrogen oxides.

Axetris IR Sources are the ideal choice for use in such diagnostic instruments.
