An important goal of space medicine is preserving high tolerance and performance of cosmonauts an ring exposure to acceleration at the final flight stage given varying mission duration. Among physiological mechanisms limiting +Gx acceleration tolerance, an important role is played by disturbances of external respiration resulting from alterations of respiratory biomechanics, pulmonary gas exchange conditions, and arterial hypoxemia. However, at present data on external respiration changes during exposure to +Gx acceleration after simulated and real microgravity of varying duration, are extremely scanty.
空间医学的一个重要目标是，在不同任务持续时间的情况下，使宇航员在飞行最后阶段暴露于加速度环境时仍保持高耐受性和良好表现。在限制 +Gx 加速度耐受性的生理机制中，呼吸生物力学改变、肺气体交换条件变化以及动脉血氧不足导致的外呼吸紊乱起着重要作用。然而，目前关于在不同时长的模拟微重力和实际微重力之后暴露于 +Gx 加速度期间外呼吸变化的数据极为匮乏。
