Abstract
  1. The breathing pattern, that is the relation between tidal volume (VT) and the inspiratory (TI) and expiratory (TE) durations, has been studied for individual breaths (forty in each steady state). 2. Five healthy subjects were studied in steady-state exercise on a bicycle ergometer breathing air; three of them were also studied in hypercapnia, at rest and during exercise, and two of them also during exercise on a treadmill. 3. Tidal volume and respiratory frequency both increased with work load. The increase in frequency was largely due to a progressive decrease in TE; TI also decreased. 4. At any constant level of respiratory drive (constant work load or chemical load) VT was positively correlated with both TI and TE in more than 95% of cases. 5. A simple model of the respiratory cycle which fits both the observed mean and breath-by-breath patterns and which involves no new assumptions is presented.
摘要
  1. 呼吸模式,即潮气量(VT)与吸气时间(TI)和呼气时间(TE)之间的关系,已针对单次呼吸进行了研究(每个稳定状态下40次)。2. 对5名健康受试者在自行车测力计上进行稳态运动时呼吸空气的情况进行了研究;其中3人还在高碳酸血症状态下、休息时和运动期间进行了研究,另外2人还在跑步机上运动时进行了研究。3. 潮气量和呼吸频率均随工作负荷增加。频率的增加主要是由于TE逐渐缩短;TI也缩短。4. 在任何恒定的呼吸驱动水平(恒定工作负荷或化学负荷)下,超过95%的情况下VT与TI和TE均呈正相关。5. 提出了一个呼吸周期的简单模型,该模型既符合观察到的平均值模式,也符合逐次呼吸模式,且无需新的假设。
