Patients transported by Helicopter Emergency Medical Services (HEMS) suffer a series of haemodynamic changes, mainly in terms of blood pressure, heart rate, and oxygen saturation, which worsen at different stages of the flight. The aim of this study was to identify haemodynamic changes in adult patients transported by the Helicopter Emergency Medical Service.
A systematic review of studies published between January 2013 to April 2023 was conducted following the PRISMA 2020 guidelines criteria in the Pubmed, Scopus and Web of Science electronic databases. Methodological quality was assessed using the critical appraisal tool for non-randomised studies of the Joanna Briggs Institute (JBI). The followed protocol has been registered in the International Prospective Register of Systematic Reviews (PROSPERO) with code CRD4202222355798. Two independent reviewers read and extracted the information of the studies.
Eight studies were included in the review, which showed significant haemodynamic changes during transport by HEMS. All studies recorded readings at three points of the mission: pre-flight, in-flight, and post-flight. The greatest change in physiological variables is visible in oxygen saturation, during the in-flight phase, with a decrease in this value. Blood pressure mainly increased in various phases of the mission, especially in the in-flight phase. Heart rate also changed across the mission phases, mainly in the pre-flight and post-flight phases, increasing and decreasing during the flight.
Patients transported by helicopter undergo haemodynamic changes during the different stages of evacuation (pre-flight, in-flight, and post-flight). However, there is a need for further studies on helicopter transport of patients due to the paucity of publications on this topic.
由直升机紧急医疗服务（HEMS）转运的患者会出现一系列血流动力学变化，主要体现在血压、心率和血氧饱和度方面，这些变化在飞行的不同阶段会恶化。本研究的目的是确定由直升机紧急医疗服务转运的成年患者的血流动力学变化。
按照PRISMA 2020指南标准，在Pubmed、Scopus和Web of Science电子数据库中对2013年1月至2023年4月发表的研究进行系统综述。使用乔安娜·布里格斯研究所（JBI）的非随机研究批判性评估工具评估方法学质量。所遵循的方案已在国际系统评价前瞻性注册库（PROSPERO）中注册，编号为CRD4202222355798。两名独立 reviewers阅读并提取了研究信息。
该综述纳入了八项研究，这些研究表明在HEMS转运过程中存在显著的血流动力学变化。所有研究在任务的三个时间点记录读数：飞行前、飞行中、飞行后。生理变量的最大变化出现在飞行阶段的血氧饱和度方面，该值下降。血压在任务的各个阶段主要升高，尤其是在飞行阶段。心率在整个任务阶段也有变化，主要在飞行前和飞行后阶段，飞行期间先升高后降低。
直升机转运的患者在疏散的不同阶段（飞行前、飞行中、飞行后）会出现血流动力学变化。然而，由于关于该主题的出版物较少，需要对患者的直升机转运进行进一步研究。
