It provides physiological information on ventilation and metabolism, which is important for airway management. The reference gas is usually gases like nitrogen which will not absorb light. Even in non-CO mixtures, our general opinion is that these sensors are best suited for spike detection only, and not for process control. This gives rise to a pressure, which is detected by the mass flow sensor. The relationship between the relaxation absorption and the gas concentration is obtained and is utilized to build a mathematical model. The gas sample becomes ionized in the flame and the electrostatic field causes the charged particles to migrate, creating a small current that is measured by the amplifier.
