肺有诸多功能(气体交换、内分泌、共鸣等),但主要功能仍然是气体交换—中间代谢;提供氧气带走二氧化碳以支持其它器官,自身也消耗氧。肺也是各种原因所致的多器官功能不全综合征(ＭＯＤＳ)中最常受累的器官。因此,肺的气体交换和氧代谢是加强监护单元(ＩＣＵ)的一项重要监测内 The lungs have many functions (gas exchange, endocrine, resonance, etc.), but the main function is still gas exchange - intermediate metabolism; providing oxygen to take away carbon dioxide to support other organs, itself also consumes oxygen. The lungs are also the most frequently affected organs in multiple organ dysfunction syndrome (MODS) due to various causes. Therefore, the lungs for gas exchange and oxygen metabolism are under intensive surveillance unit (ICU) monitoring
