许多功能检查都运用在职业病临床中,特别对早期诊断有重要意义,作者介绍了在其临床中获得证实的一些检查方法。为了解高温作业不良气象条件对心血管系统的影响,在血液循环机能试验中可用间接法(脉搏与脉压的乘积)来确定心脏每分输出量的动态,该值的增长主要是由于脉压的增大,此为体力劳动后当舒张压稳定或变化很小时收缩压增高所致,故血液循环器官功能降低起主要作用的不是心肌无力而是血管机能的下降,此外,工后检查脉
Many functional tests are used in occupational disease clinics, especially for early diagnosis of great significance, the author introduced some confirmed in its clinical examination methods. In order to understand the effects of adverse weather conditions at high temperature on the cardiovascular system, an indirect method (product of pulse and pulse pressure) can be used to determine the dynamics of cardiac output per minute during the functional tests of blood circulation. This increase is mainly due to pulse pressure Of the increase, which is due to manual labor when the diastolic blood pressure is stable or small changes caused by increased systolic blood pressure, the role of the lower circulatory system function is not the main role of myocardial weakness but decreased vascular function, in addition, post-operative check pulse
