本研究表明，心输出量和其他相关的心肺参数的准确估计，可以获得非侵入性的呼吸数据驱动系统与适当设计的解释性输入。该输入包括在1分钟的总持续时间内连续进行3次大于正常呼吸的3次呼吸和12秒屏气。密切关注建模和计算的细节，以尽量减少随机和系统误差的影响。所有参数的估计总误差小于9%。
The present study demonstrates that accurate estimates of cardiac output and other related cardiopulmonary parameters can be obtained noninvasively from respiratory data by driving the system with an appropriately designed ventilatory input. This input consists of a sequence of 3 larger-than-normal breaths and a 12-second breathhold performed 3 times in succession over a total duration of 1 minute. Close attention is given to modeling and computational details in order to minimize the effects of random and systematic errors. The estimated total error is less than 9 percent in all the parameters.
