Haemodynamic monitoring may potentially lead to improved quality of care in haemodynamic compromised patients. However, the usefulness of invasive techniques using the pulmonary artery catheter is questioned. Noninvasive techniques which provide data on haemodynamics might provide a good alternative. New techniques have been developed in recent years to monitor cardiac output and other parameters of cardiac performance continuously and noninvasively. Recently, a new technique has become available that assesses these haemodynamic data from finger arterial pressure waveforms obtained noninvasively. Although an invasively derived calibration is still needed to obtain absolute data on cardiac output, relative changes in cardiac output can be accurately monitored using this method. Currently, the device can be used in patients to continuously monitor haemodynamic data and guide therapy. Furthermore, it might have a role in clinical research to noninvasively assess cardiac output, as a surrogate endpoint, before and after interventions. Although this new method seems promising, the clinical value has to be proven.
血流动力学监测可能会潜在地提高血流动力学受损患者的护理质量。然而，使用肺动脉导管的侵入性技术的实用性受到质疑。提供血流动力学数据的非侵入性技术可能是一个很好的替代方案。近年来已开发出新技术，可连续、非侵入性地监测心输出量和其他心脏功能参数。最近，出现了一种新技术，可从无创获取的手指动脉压波形评估这些血流动力学数据。尽管仍需要侵入性校准来获取心输出量的绝对数据，但使用此方法可准确监测心输出量的相对变化。目前，该设备可用于患者以连续监测血流动力学数据并指导治疗。此外，它在临床研究中可能有助于在干预前后作为替代终点非侵入性地评估心输出量。尽管这种新方法似乎很有前景，但仍需证明其临床价值。
