The uptake of oxygen and excretion of carbon dioxide by the lungs gives a measure of the body s metabolism. Measurements of these gases are required for monitoring clinical procedures such as anaesthesia, and are also necessary in experimental medicine, where the aim is to understand their involvement in biological regulation. The problem in such measurements is that they need to be direct and fast, so that changes during the breath cycle can be accurately monitored. This proposal seeks to introduce novel methods of laser absorption into a clinical setting by adapting present techniques used in a physical chemistry laboratory so that they can be applied in medical monitoring and investigation.

肺对氧气的吸收和二氧化碳的排泄是衡量身体新陈代谢的一个指标。这些气体的测量是需要监测临床程序，如麻醉，也是必要的实验医学，其目的是了解它们参与生物调节。这种测量的问题在于它们需要直接和快速，以便可以准确地监测呼吸周期期间的变化。该提案旨在通过调整物理化学实验室中使用的现有技术，将激光吸收的新方法引入临床环境，以便它们可以应用于医学监测和调查。
