This is an overview of investigations performed in actual and simulated flights to study the effects of microgravity and acceleration, space cabin and space suit artificial atmosphere on the respiratory function. The conceptual prediction of the effects that the space environment produces on the respiratory system suggests the following changes in respiration, gas exchange, and acid-base equilibrium: respiration biomechanics; gas diffusion and ventilation-perfusion ratios in the lungs; regulation of respiration and function of respiratory muscles; lung hydration and blood filling; respiratory changes in acid-base equilibrium and blood gases. Besides, the combined effect of microgravity, acceleration, low barometric pressure and modified gas composition may cause lung atelectases and concomitant disorders in pulmonary ventilation and gas exchange. These changes may have an adverse effect on the health condition and physical work capacity.
这是一篇关于在实际飞行和模拟飞行中所进行调查的综述，旨在研究微重力、加速度、太空舱及太空服人造大气对呼吸功能的影响。对太空环境对呼吸系统产生的影响进行的概念性预测表明，呼吸、气体交换及酸碱平衡会发生以下变化：呼吸生物力学；肺部的气体扩散及通气/灌注比；呼吸调节及呼吸肌功能；肺水合作用及血液充盈；酸碱平衡及血气的呼吸变化。此外，微重力、加速度、低气压及气体成分改变的综合作用可能会导致肺不张以及随之而来的肺通气和气体交换紊乱。这些变化可能会对健康状况和身体工作能力产生不利影响。
