The analysis of the breath of patients offers various possibilities to monitor the condition of respirated or anesthetized patients or to gather findings about the functionality of the respiratory system and the human body.
A typical focus of the respiratory gas analysis is the end-tidal CO2 concentration of the patient’s exhaled air, which is determined by the capnography or capnometry. Today, it is a widely used technique in emergency medicine, in clinical applications and in performance diagnostics.
Corscience’s own measurement module for capnography is based on the fact that different gases have a different absorbance in the infrared spectrum, i.e that certain IR wavelength dampen differently. The magnitude of the dampening allows us to draw conclusions about the partial pressure of the respective gas using the Lambert-Beer law.
Apart from capnography, the measurement of oxygen in the respiratory gas analysis is becoming increasingly important. Typical applications include the inspiratory O2 measurement in anesthesia and respiration equipment and expiratory O2 measurement in cardiopulmonary exercise testing.
Corscience deals intensively with the possibilities of respiratory gas analysis. With the CAP201, Corscience provides its customers with a reliable and established capnography module. Moreover, Corscience is currently developing a non-consumable O2 sensor, which will be available in the future as a module for the reliable and robust measurement of oxygen in respiratory gas analysis.
