无创连续血压(BP)测量已成为远程医疗保健领域中不断发展的主题。经典的无创BP测量技术可提供收缩压和舒张压的自发值。另一方面,侵入式BP测量技术提供了收缩压和舒张压的连续值。然而,这些技术非常痛苦,不能用于长期监测,并且只能在重症监护病房环境中获得。随着远程医疗行业的发展,无创连续BP监测的需求不断增长。
本研究的目的是提供有关无创连续BP测量技术的各种前瞻性方法的紧凑文献综述。
无创连续BP测量的最现代和最先进的技术是触觉传感,血管卸载技术,脉冲传输时间,光电容积描记术,基于超声的BP测量,来自图像处理的BP测量,等。在EMBASE中进行了基于这些技术的文献检索,WebofScience,IEEE,PubMed,和OvidMEDLINE数据库。在这项研究中,使用以下标准对每种选择的方法进行了评估和表征:(1)准确性;(2)成本;(3)便携性;(4)使用的舒适性和便利性;(5)临床健康和安全性;(6)与远程医疗保健系统的集成能力.
进行了详细的技术分析,以确定在上述参数的背景下每种技术的优点和局限性。据观察,BP测量,使用光电体积描记术(使用相机或传感器或两者),也许是最有前途的技术。
这项研究强调了这样一个事实,即非侵入性,连续BP测量技术需要进一步发展以使其可靠,准确,和用户友好。最后,讨论了朝着更可靠,更舒适的无创连续BP测量技术的可能方向。
Noninvasive continuous blood pressure (BP) measurement has become an evolving topic in the field of remote healthcare. The classical noninvasive BP measurement techniques provide spontaneous values of systolic and diastolic BP. On the other hand, intrusive type BP measurement techniques provide continuous values of systolic and diastolic BP. However, these techniques are very painful, cannot be used for long-term monitoring, and are obtainable only in an intensive care unit environment. With the advancement of the remote healthcare industry, there is a growing demand for noninvasive continuous BP monitoring.
The objective of this research was to present a compact literature
review on the various prospective approaches of noninvasive continuous BP measurement techniques.
The most contemporary and advanced technologies on noninvasive continuous BP measurement are Tactile Sensing, Vascular Unloading Technique, Pulse Transit Time, Photoplethysmography, Ultrasound-based BP measurement, BP measurement from image processing, etc. The literature search based on these technologies was conducted in EMBASE, Web of Science, IEEE, PubMed, and Ovid MEDLINE databases. In this study, each selected approach was evaluated and characterized using the following criteria: (1) accuracy; (2) cost; (3) portability; (4) comfort and convenience of use; (5) clinical health and safety; and (6) ability to integrate with the remote healthcare system.
A detailed technical analysis was done to determine the advantages and limitations of each technique in the context of the abovementioned parameters. It was observed that BP measurement, using photoplethysmography (using camera or sensor or both), perhaps was the most promising technique among all.
The study emphasized the fact that the noninvasive, continuous BP measurement technique needs to evolve further to make it reliable, accurate, and user-friendly. Lastly, a possible direction toward a more reliable and comfortable noninvasive continuous BP measurement technique has been discussed.
