There are several gases to be detected for safety reasons, but CO2 reveals a lot. The anesthesiologist monitors the respiration (CO2) of the patient, and that information reveals the exact stage of anaesthesia.

In a care situation, the same monitoring (capnography) is done to the patient’s exhalation to learn how a treatment is working, or if there are other factors that do not respond well to change in the CO2 level.

There are several applications related to sensors within the Life science segment (e.g. incubators, carbon patients, alarms) in situations where CO2 is used:

  • Respiration and help to overcome breath-holding and bronchial spasms
  • To facilitate blind intubation in anaesthetic practice
  • To facilitate vasodilation and thus lessen the degree of metabolic acidosis during the induction of hypothermia
  • To increase cerebral blood or in arteriosclerotic patients undergoing surgery
  • To stimulate respiration after a period of apnea
  • In chronic respiratory obstruction after it has been relieved
  • To prevent hypocapnia during hyperventilation
  • For clinical and physiological investigations
  • In gynaecological investigation for insufflation into fallopian tubes and abdominal cavities as solid carbon dioxide (dry ice) in tissue freezing techniques
  • For the destruction of warts by freezing 

Future use of the Capnometer

With our High-Resolution Platform (HPP), CO2 can be monitored without intruding on the user’s integrity. This will open an opportunity for the elderly and their relatives to increase safety in daily life.

Sensor challenges

Due to the importance of human safety in emergency situations, the sensor has to work flawlessly and quickly. From the first breath, the monitoring system has to deliver exact levels to the equipment. The character of the curve created gives the trained staff important information on traumas, inner bleedings, brain damage, etc. Working temperature can be extreme (from -5 to +40°C) and humidity can vary from 10% to 90% (non-condensing).
