Cubic Gas Sensing Solution for Pulmonary Function Test

Innovative Gas Sensing Solutions for Advanced Pulmonary Function Testing

The cardiopulmonary system is recognized as one of the most essential physiological systems in the human body, with the responsibility of efficiently distributing blood and oxygen to every organ. The cardiopulmonary system is closely linked to human health. Therefore, pulmonary function testing is crucial for both disease prevention and diagnosis.

Since different diseases lead to distinct abnormalities, pulmonary function tests play a pivotal role in accurately assessing the nature and severity of these abnormalities. Although spirometry stands as the most commonly utilized method among these tests, spirometry alone may not always provide a comprehensive and precise diagnosis of lung function. To further evaluate the efficiency of gas exchange in the lungs, DLCO (diffusing capacity of the lungs for carbon monoxide) testing is frequently employed in conjunction with spirometry. This test yields more precise measurements of the lung’s capacity to transfer gas from inspired air into the bloodstream and offers valuable insights into lung function beyond what spirometry can provide.

With 20-year dedication to the development of gas sensing technologies, Cubic, an international manufacturer of advanced gas sensors and gas analyzers, has accumulated mature sensing technology platform of non-dispersive infrared (NDIR) to deliver innovative gas sensing solutions supporting DLCO test.

NDIR (Non-dispersive Infrared) Sensing Technology:

NDIR technology is utilized based on the principle that certain gases absorb infrared light at specific wavelengths. The detector captures and quantifies this infrared absorption, enabling accurate assessment of gas concentrations through algorithmic analysis embedded in the software.

Cubic NDIR DLCO Sensor Gasboard-2050：

Leveraging NDIR technology, Cubic has innovatively developed DLCO gas sensor, Gasboard-2050, which can realize online measurement of CO and CH4.

Adopting an electrically modulated IR source, Gasboard-2050 achieves a fast response time of less than 150 milliseconds. With its temperature and pressure compensation algorithm design, Gasboard-2050 operates with high accuracy and excellent stability under a wider range of atmospheric, temperature, and humidity conditions. Additionally, the modular design of Gasboard-2050 enables easy assembly, ensuring exceptional availability and high-volume throughput during manufacturing.

With its excellent accuracy and stable performance, Cubic DLCO sensor Gasboard-2050 emerges as a valuable diagnostic instrument in pulmonary testing. It equips healthcare professionals with reliable and precise measurements of lung function, thereby enabling them to make more accurate diagnoses and tailor personalized treatment plans for patients with respiratory conditions.
