During the first four flights of the space shuttle, cardiovascular data were obtained on each crewmember as part of the operational medicine requirements for crew health and safety. From monitoring blood pressure and electrocardiographic data, it was possible to estimate the degree of deconditioning imposed by exposure to the microgravity environment. For this purpose, a quantitative cardiovascular index of deconditioning (CID) was derived to aid the clinician in his assessment. Isotonic saline was then investigated as a countermeasure against orthostatic intolerance and found to be effective in partially reversing the hemodynamic consequences. It was observed that the space flight environment of reentry might potentially be arrhythmogenic in at least one individual.
在航天飞机的前四次飞行中，作为保障机组人员健康与安全的运行医学要求的一部分，获取了每位机组人员的心血管数据。通过监测血压和心电图数据，能够估算出暴露于微重力环境所导致的身体机能衰退程度。为此，推导了一个定量的心血管机能衰退指数（CID），以协助临床医生进行评估。随后研究了等渗盐水作为对抗体位性不耐受的对策，发现其在部分逆转血液动力学后果方面有效。据观察，重返大气层的太空飞行环境可能至少对一人有潜在致心律失常作用。
