尘肺能引起不同程度的肺功能改变,影响患者的劳动能力。多年来,许多学者从临床,x线形态学、呼吸生理学、运动生理学等不同角度进行了探索。本文就近年来有关这方面的研究情况作一介绍。一、损伤与劳动能力丧失的区别在我国目前并没有严格区分功能损伤与劳动能力丧失这两个概念。实际上这是两个不同的概念。Gaensler认为损伤是机体或器官功能的下降,劳动能力丧失则是机体缺少从事某种特殊活动的能 Pneumoconiosis can cause varying degrees of lung function changes, affecting the patient’s ability to work. Over the years, many scholars from the clinical, x-ray morphology, respiratory physiology, exercise physiology and other different angles were explored. This article gives an introduction on the research situation in this area in recent years. First, the difference between impairment and loss of ability to work In our country, there is no strict distinction between the two concepts of functional impairment and loss of working ability. In fact, this is two different concepts. Gaensler that injury is the decline in body or organ function, loss of ability to work is the body lack the ability to engage in a particular activity
