Description

监护系统、房颤综合管理的方法和显示监护数据的方法 技术领域
本发明涉及医疗器械领域,具体涉及监护系统、房颤综合管理的方法和显示监护数据的方法。
背景技术
心房颤动(atrial fibrillation, AF),简称房颤,是心内科最为常见的心律失常之一。房颤的发病率随年龄增长逐步增加,在80岁以上人群中高达7.5%。房颤在心脏重症监护中极为常见,例如,重症心衰患者的房颤发生率高达55%。为及时发现和评估房颤,医护人员常使用床边监护仪对病人进行实时连续监测。现有监护系统通常只是检测房颤并报警,例如当监护仪通过后台算法检测到心电图上有房颤发生时,便会在报警区自动弹出“房颤”字符串,并通过声光提示提醒医护人员关注,当房颤结束而恢复窦性节律时,便会在报警区自动弹出“房颤停止”字符串;除了上述实时报警外,医护人员还可通过回顾界面的事件列表翻看历史报警数据。然而,医护人员光靠房颤报警以及房颤发生时的心电波形无法对患者有个综合判断,故医护人员管理房颤的效率较低。

本发明的实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中,很多细节描述是为了使得本申请能被更好的理解。然而,本领域技术人员可以毫不费力的认识到,其中部分特征在不同情况下是可以省略的,或者可以由其他元件、材料、方法所替代。在某些情况下,本申请相关的一些操作并没有在说明书中显示或者描述,这是为了避免本申请的核心部分被过多的描述所淹没,而对于本领域技术人员而言,详细描述这些相关操作并不是必要的,他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外,说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时,方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此,说明书和附图中的各种顺序只是为了清楚描述某一个实施例,并不意味着是必须的顺序,除非另有说明其中某个顺序是必须遵循的。
本文中为部件所编序号本身,例如“第一”、“第二”等,仅用于区分所描述的对象,不具有任何顺序或技术含义。而本申请所说“连接”、“联接”,如无特别说明,均包括直接和间接连接(联接)。
本发明提供的监护系统、房颤综合管理的方法和显示监护数据的方法,通过房颤综合视图(AF View)的设计将房颤事件、生命体征参数和房颤负荷等信息集中呈现,为医护人员系统评估患者的生理状态提供帮助。
如图1所示,本发明提供的监护系统,包括信号采集器10、处理器20、显示器30和输入装置40。
输入装置40构造为用于接收用户(通常是操作者)的输入,例如,可以采用鼠标、键盘、触控显示器、轨迹球和操纵杆中的一个或多个等,以接收用户输入的指令等。用户通过输入装置40可进行输入操作。
显示器30构造为用于输出信息,例如输出可视化信息。显示器30可以采用只具备显示功能的显示器,也可以采用触控显示器。可见,显示器30和输入装置40为监护系统的人机交互装置,人机交互装置既能接收用户输入的指令,又能显示可视化信息。
信号采集器10用于获取监护数据,例如,获取患者的至少两项生命体征参数的监护数据,其中,所述至少两项生命体征参数中包括心电参数(心电信号)。
监护系统可以是监护仪、本地中央站、远程中央站、云端服务系统、移动终端中的任一个,相应的信号采集器10获取监护数据的方式也是不同的。例如,监护系统是监护仪,则信号采集器10可采用传感器,传感器用于监护患者的生命体征参数,得到生命体征参数的监护数据。生命体征参数的监护数据可以包括生命体征参数种类(如心电、呼吸、无创血压、血氧饱和度、脉搏、体温、有创血压、呼吸末二氧化碳、呼吸力学、麻醉气体、心输出量、脑电双频指数中的一种或多种等)、生命体征参数数值、生命体征参数数值的变化趋势中的至少一种。又例如,监护系统可以是本地中央站、远程中央站、云端服务系统或移动终端,则信号采集器10为通信装置或通信接口,用于与监护仪通信连接,从监护仪中获取上述监护数据。
处理器20可以构造为用于基于信号采集器10获取的监护数据进行房颤检测,得到房颤分析结果,房颤分析结果中至少包括患者发生的房颤事件的信息。当然,由于现有的监护仪能记录房颤事件,故处理器20也可以通过信号采集器10从监护仪中获取患者发生的房颤事件的信息。处理器20根据房颤事件的信息和所述至少两项生命体征参数的监护数据,生成房颤综合视图并输出。处理器20输出房颤综合视图,例如可以是显示房颤综合视图,也可以是输出电子版的概览报告,还可以通过连接的打印设备打印纸质的概览报告;本实施例中以显示房颤综合视图为例进行说明,如图2所示,房颤综合视图中包括:所述至少两项生命体征参数的趋势图810、房颤事件趋势图820,以及房颤负荷图830。应理解的是,概览报告中除了包含与房颤事件相关的信息(例如房颤综合视图),还可以包含房颤事件以外的、表征患者其他生命体征情况、诊断内容、检验结果等信息。
趋势图又称为推移图、运行图、链图、走势图等等。趋势图可以用于反映某一个或多个变量与时间之间的关系,即,该一个或多个变量随时间变化发展的趋势。例如,趋势图可以以时间为横轴,待观察的变量为纵轴,观察变量变化发展的趋势和/或偏差。其横轴时间可以是秒、分钟、小时、日、月、年等,各时间点应连续不间断,纵轴的观察变量可以是绝对量/绝对值、平均值、发生率等。在本文中,生命体征参数的趋势图可以用来反映某一生命体征参数随着时间变化的趋势,例如,该生命体征参数的参数值随时间推移而不断变化的数值,该参数值既可以是以一定采样率采集的绝对值,也可以是以一定采样率采集并计算而得的各个固定时间段内的平均值。因此,对于生命体征参数而言,其趋势图中的“变量”通常为该生命体征参数的参数值。房颤事件趋势图可以用来反映房颤事件随着时间变化的趋势,例如,随时间推移房颤事件变化发展的发生形态、发展态势、发生率、趋势等等。此处,“发生率”可以是事件在最小单位时长内的发生频率,而发生形态、发展态势、趋势等等,则不限于发生频率,而是例如可以根据事件发生的实际情况进行的标记,例如,每发生一次房颤事件,用特殊图形/符号等进行一次标记,当为连续地、长时地发生的房颤事件时,可以用图形/符号等随着横轴(即时间轴)的跨越长度来反映该次房颤事件发生的时长。在后文中,将结合图3具体描述各种趋势图所反映的房颤事件的发生形态、发展态势、发生率、趋势等等。
至少两项生命体征参数的趋势图810用于呈现至少两项生命体征参数在预设房颤监测期内的变化。即,生命体征参数的趋势图810用于呈现该生命体征参数在预设房颤监测期内的变化。房颤综合视图中显示的生命体征参数趋势图,可以包括心率的趋势图、脉率的趋势图、血氧的趋势图、无创血压的趋势图、有创血压的趋势图、呼吸的趋势图、体温的趋势图、每搏心输出量的趋势图、心排量的趋势图、心电图ST段、心电图QT间期、血糖、脑氧、尿量中的至少一个。生命体征参数的趋势图反映生命体征参数的变化趋势即可,其可以是曲线图、直方图、条形图、箱线图、散点图、折线图之一,也可以是曲线图、直方图、条形图、箱线图、散点图、折线图中的各种组合。本实施例中,生命体征参数的趋势图810以曲线图为例进行说明。
房颤事件趋势图820用于呈现在预设房颤监测期内患者发生的房颤事件,例如,呈现房颤事件次数和/或频率在预设房颤监测期内的变化。房颤事件趋势图820反映房颤事件的变化趋势即可,其可以是曲线图、直方图、条形图、箱线图、散点图、折线图之一,也可以是曲线图、直方图、条形图、箱线图、散点图、折线图中的各种组合。通过房颤事件趋势图820,医生可以看到想要关注的时间段内是否发生了房颤,房颤事件的分布(发生次数、持续时间)情况,房颤发生的有和无等,非常方便。
房颤负荷图830用于呈现预设房颤监测期内至少一个最小单位时间段内的房颤负荷。通过房颤负荷图830,可以直接定量的给出每个最小单位时间段之间的负荷变化,医生可以看到房颤累积程度的多与少,负荷的高于低,非常方便。最小单位时间段可以是系统自动预设的,也可以是用户输入的或用户更改的。图2所示的实施例中,最小单位时间段为1小时。最小单位时间段可以与更新周期相同,也可以不同,本实施例以前者为例进行说明。图2列举了一种房颤负荷图830,其为统计直方图,其中直方图的每一个条形块的高度代表每个最小单位时间段内的房颤负荷,最大值100%意味着患者在这个最小单位时间段内一直持续发生房颤,条形块的宽度即为最小单位时间段的时长,可由用户设定。如图11所示,其中直方图上边沿拟合了一条连续曲线,代表了房颤监测期内整个房颤负荷的变化分布。
并且,至少两项生命体征参数的趋势图810、房颤事件趋势图820以及房颤负荷图830同时显示,以便于联合呈现预设房颤监测期内任意一个或多个时刻或时间段内至少一项生命体征参数、患者发生的房颤事件以及房颤负荷中至少两者之间的相关性。
传统的监护设备对于房颤管理主要局限于事件报警和回顾,且回顾内容大多局限在回顾列表中简单呈现报警时刻,或提供一段典型的参数(一般为心电图)波形供用户查看。本发明围绕心电参数,提供了一套更为完善的房颤综合管理方法,涉及生命体征参数、房颤事件、房颤负荷的联合呈现,各种信息相互联系、有机结合。可见,医生能通过房颤综合视图了解患者的综合情况,便于快速的采取应对措施,提高了房颤管理的效率。
如图4所示,处理器20包括:房颤配置单元210,房颤分析单元220,房颤报警单元230和房颤负荷显示单元240。
房颤配置单元210用于为医护人员提供房颤分析和管理的个性化配置,如图6所示,包括但不限于房颤分析导联选择、房颤报警级别设置、房颤负荷显示区域设置、房颤监测期设置、房颤负荷的更新周期设置、房颤负荷显示阈值设定(该阈值含义:当房颤负荷超过该阈值时才会显示,若没超过该阈值,那么在心电波形区或参数区不会显示房颤负荷值)等。
处理器20各个单元进行房颤综合管理的过程如图5所示,包括如下步骤:
步骤1、房颤分析单元220根据房颤配置单元210的参数配置,通过信号采集器10获取患者的至少两项生命体征参数的监护数据,获取的生命体征参数的监护数据中包括心电参数的监护数据。获取生命体征参数的监护数据可以有多种方式,例如方式一:获取实时的监护数据,方式二:获取预设房颤监测期内的监护数据,下面一一说明。
方式一中,房颤分析单元220通过信号采集器10实时获取患者的至少两项生命体征参数的监护数据。以信号采集器10为传感器为例,传感器收集和预处理患者的生命体征参数的监护数据,其中就包括一个导联的心电参数,得到对应的实时监护数据。以信号采集器10为通信装置或通信接口为例,房颤分析单元220通过通信装置或通信接口,从监护仪中实时获取生命体征参数的监护数据。通过持续不断的获取实时监护数据,最终使得房颤事件趋势图能呈现预设房颤监测期内的各项数据。房颤分析单元220还用于根据心电参数的实时监护数据通过显示器30显示实时心电波形,例如图8所示,将实时心电波形(A区域所示)显示在实时界面监护图上,便于医护人员对患者的心电信号进行日常监护。
方式二中,房颤分析单元220通过信号采集器10获取预设房颤监测期内患者的至少两项生命体征参数的监护数据。同样的,以信号采集器10为传感器为例,传感器收集和预处理了预设房颤监测期内患者的生命体征参数的监护数据。以信号采集器10为通信装置或通信接口为例,房颤分析单元220通过通信装置或通信接口,从监护仪中获取预设房颤监测期内患者的生命体征参数的监护数据。通过一次性获取房颤监测期内各项生命体征参数的监护数据,最终使得房颤事件趋势图能呈现预设房颤监测期内的各项数据。预设房颤监测期可以是系统自动预设的,例如房颤配置单元210中预先存储有一个房颤监测期,也可以是用户输入或更改的,例如,房颤配置单元210通过显示器提供一设置界面,如图6,用户在图6所示的界面中通过输入装置输入或更改房颤监测期,则房颤配置单元210得到新的房颤监测期,进而,房颤分析单元采用新的房颤监测期更新房颤综合视图。房颤监测期可以以小时计、以天计等,本实施例中房颤监测期以24小时为例进行说明。
当然,方式一和方式二仅用于举例说明,还可以有其他方式,本发明对获取生命体征参数的监护数据不作限制,只要能提供房颤综合视图所需的数据即可。
步骤2、获取患者发生的房颤事件的信息。具体可以有多种方式,例如,步骤1获取的是实时监护数据,则房颤分析单元220基于获取的实时监护数据进行房颤检测,得到房颤分析结果,房颤分析结果中至少包括患者发生的房颤事件的信息。具体的,房颤分析结果可以根据心电参数的监护数据进行房颤检测得到,也可以根据其他参数例如血氧参数、有创血压和/或无创血压的监护数据进行房颤检测得到,本实施例以前者为例进行说明。房颤分析单元220通过信号采集器10实时获取患者的心电参数的监护数据,房颤分析单元220对实时的心电参数的监护数据进行房颤检测,若发生房颤则生成房颤事件的信息和房颤的持续时间段。例如,房颤分析单元220对实时的心电参数的监护数据进行噪声处理;进行P波分析得到P波的有无、P波的起止点、峰值点等;进行f颤动波分析得到f颤动波的有无;进行RR间期不规则度分析,具体的,基于相邻R波计算RR间期长短,其倒数就是心率,对预设的一段时间内,RR间期组成的序列进行不规则度分析,判断得到当前段落心率是否绝对不匀齐;进行心搏分类,得到心搏分类结果,心搏分类结果有:窦性、房性、室性以及其它类别这4种;通过上述的一种或多种分析,得到患者发生的房颤事件的信息,例如房颤事件发生的起始时刻与停止时刻等,并存储房颤事件的信息。房颤分析单元220将房颤事件的信息输出给房颤报警单元230和房颤负荷显示单元240。房颤事件是一次房颤,也对应一次房颤报警。
监护系统还可以包括蜂鸣器、扬声器和/或警示灯等。房颤报警单元230接收到房颤事件的信息则说明发生房颤,可以通过蜂鸣器或扬声器发出声音报警提示,也可以通过警示灯发出灯光报警提示,还可以通过显示器显示房颤报警信息,例如显示图形文字(在显示器显示界面顶端的报警区实时显示的报警字符串)等,通过上述报警方式向用户发出房颤开始和结束的报警提示。如图8所示,区域B显示的“房颤”即为一种房颤报警信息,其显示在实时界面监护图上,可有效的进行房颤报警。
房颤负荷显示单元240接收房颤分析单元220输出的房颤事件的信息,然后基于房颤起始与停止时刻计算得到房颤的持续时间段,根据房颤的持续时间段以及预设的更新周期计算得到实时房颤负荷,定义房颤负荷的方法很多,如预设的更新周期(一个预设的时间段)内房颤发生最长的持续时间、房颤发生的数量或房颤持续时间段所占的百分比,本实施例中,将房颤的持续时间段在更新周期中所占的百分比作为房颤负荷(AF Burden)。预设的更新周期可以是系统自动预设的,也可以是用户输入或更改的,其可以以分钟计、以小时计等,本实施例中更新周期以1小时为例进行说明。房颤负荷显示单元240在显示器的显示界面显示实时房颤负荷,可以将实时房颤负荷显示在房颤综合视图中,如显示在图2的参数趋势区或典型波形区,即房颤综合视图还包括实时的房颤负荷信息,也可以将实时房颤负荷显示在其他显示界面,如显示在图9所示的界面,图9中C区域显示的实时房颤负荷(AF Burden)为5%。实时房颤负荷中所谓的“实时”是基于一定秒数、分钟或小时进行刷新,即基于更新周期进行刷新,用户可配置更新周期,当然也可依据房颤报警事件的出现时刻进行数值刷新。
又例如,步骤1获取的是预设房颤监测期内的监护数据,则房颤分析单元220基于获取的监护数据进行房颤检测,得到房颤分析结果,本实施例中,房颤分析单元220对预设房颤监测期内心电参数的监护数据进行房颤检测,得到房颤分析结果,房颤分析结果中至少包括在预设房颤监测期内患者发生的房颤事件的信息。具体过程同上述实时房颤检测,在此不做赘述。
在有的实施例中,房颤分析单元220还可以通过信号采集器10从监护仪中直接获取实时的房颤事件的信息,或者通过信号采集器10从监护仪中直接获取在预设房颤监测期内患者发生的房颤事件的信息。
步骤3、房颤分析单元220根据获取的房颤事件的信息和所述至少两项生命体征参数的监护数据,显示房颤综合视图。房颤综合视图可以自动显示,也可以在某些条件下触发显示,例如,上述内容中提到了在检测到房颤时房颤报警单元230通过显示器30显示房颤报警信息,可以在输入装置40接收到用户点击房颤报警信息的操作时,房颤分析单元220通过显示器30显示房颤综合视图,换而言之,当输入装置40接收到用户点击房颤报警信息的操作时,进入步骤3。可见,医生在图8所示的界面看到“房颤”的报警信息后,操作输入装置40点击区域B,即可呈现房颤综合视图,看到更为详细的各种数据,提高了医生对患者房颤管理的效率。
又例如,上述内容中提到了房颤负荷显示单元240根据预设的更新周期计算得到实时的房颤负荷,并通过显示器显示实时房颤负荷信息,可以在输入装置40接收到用户点击实时房颤负荷信息的操作时,通过显示器显示房颤综合视图。换而言之,当输入装置40接收到用户点击实时房颤负荷信息的操作时,进入步骤3。可见,医生在图9所示的界面看到“AF burden 5%”后,操作输入装置40点击区域C,即可呈现房颤综合视图,看到更为详细的各种数据,提高了医生对患者房颤管理的效率。
又例如,上述内容中提到了房颤分析单元220根据心电参数的监护数据通过显示器显示实时心电波形,可以在输入装置40接收到用户点击实时心电波形的操作时,通过显示器显示房颤综合视图。换而言之,当输入装置40接收到用户点击实时心电波形的操作时,进入步骤3。可见,医生在图8所示的界面看到实时心电波形后,操作输入装置40点击区域A,即可呈现房颤综合视图,看到更为详细的各种数据,提高了医生对患者房颤管理的效率。
当然,监护系统还可以预先设置一个热键,在输入装置40接收到用户点击预设热键的操作时,房颤分析单元220通过显示器显示房颤综合视图,即进入步骤3。可见医生可以一键看到房颤综合视图,非常方便。
监护系统监护多个患者时,其常用的显示界面如图7所示,01-05表示患者的床位。在输入装置40接收到用户选定02床的患者时,即用户操作输入装置点击K区域中的任意点时,显示界面跳转至图10所示的界面。监护系统还提供心电参数的回顾功能,在输入装置40接收到用户输入的回顾第一预设时间段的概览报告的指令时,房颤分析单元220获取在第一预设时间段检测一项或多项生命体征参数得到的监护数据,根据第一预设时间段的一项或多项生命体征参数的监护数据生成概览报告并在显示器上显示。以概览报告为心电概览为例,房颤分析单元220获取在第一预设时间段检测心电参数得到的监护数据,根据第一预设时间段的心电参数的监护数据生成并在显示器上显示概览报告。医生可以回顾第一预设时间段心电参数的监护数据,便于掌握患者病情。当然,概览报告还可以是其他生命体征参数的概览,在此不做赘述。第一预设时间段可以是系统自动预设的,也可以是用户输入或更改的。如图10所示,用户通过输入装置点击图10所示界面的“Summary”即可呈现概览报告。概览报告中包括目标虚拟按键,如图10中“房颤概览”的下拉菜单,在输入装置40接收到用户点击目标虚拟按键的操作时,例如图10中通过下拉菜单选取“房颤概览”,房颤分析单元220在显示器上显示房颤综合视图(图10中“房颤概览”的下拉菜单以下的部分),即进入步骤3,此时显示的房颤综合视图,其房颤监测期可以是第一预设时间段,也可以是第一预设时间段内的一段时间。医生在回顾患者的心电信号时,只需一键操作,即可查看房颤综合视图,进一步掌握患者的房颤情况,无需来回切换显示界面,操作方便快捷。
本实施例中,医生可通过上述各种方式使监护系统显示房颤综合视图,便于医生快速掌握患者的病情。
房颤综合视图中包括:所述至少两项生命体征参数的趋势图810、房颤事件趋势图820,以及房颤负荷图830。房颤综合视图中显示哪些生命体征参数,可以是系统预先设置好的,也可以由用户预先进行设置,例如显示心率、脉率、血氧、无创血压、有创血压、呼吸、体温、ST段信息等生命体征参数。
在房颤综合视图中,至少一项生命体征参数的趋势图810和房颤事件趋势图820同时显示,本实施例中,获取了多少项生命体征参数的监护数据就对应显示多少项生命体征参数的趋势图810,便于联合呈现预设房颤监测期内任意一个或多个时刻或时间段内房颤事件的发生与否对至少一项生命体征参数所产生的影响;也便于联合呈现预设房颤监测期内任意一个或多个时刻或时间段内房颤事件的分布情况对至少一项生命体征参数所产生的影响。
可通过比较生命体征参数和房颤事件的变化趋势,来判断房颤是否对生命体征参数有影响。例如,从图2中可以看到,随着房颤的发生,心率(HR)越来越高,后续房颤少了,心率就慢慢降下来了,说明房颤对心率有影响。反之,若心率升高时没有房颤发生,则表明心律升高不是受房颤的影响。可见,房颤事件趋势图820和心率的趋势图810联合呈现,医生可以更精细地查看房颤发生与否,查看房颤与心率变化有无关系。同样的,房颤事件趋势图820和心电波形的ST段联合呈现,同理,可以更精细化地看房颤有、无,对于ST的影响。器质性心脏病发生房颤的症状一般较重,当心室率超过150次/分时,可诱发冠心病患者发生心肌缺血而产生心绞痛,可诱发原有心功能障碍者产生急性心衰,故医生通过房颤综合视图可快速判断患者是否有危险,进而可及时采取干预措施。可见,生命体征参数的趋势图810和房颤事件趋势图820同时显示,便于医生快速分析出两者之间的相关性。
房颤事件趋势图820和房颤负荷图830同时显示,以便于联合呈现预设房颤监测期内具有特定房颤负荷值的不同时间段内的房颤事件的分布情况的差异。特定房颤负荷值可以是医生感兴趣的房颤负荷值。房颤事件趋势图820和房颤负荷图830两者对照,可以呈现不同的信息:同样的房颤负荷下,不同时段的房颤事件分布可能差异很大。例如,房颤负荷同样是50%,通过结合房颤事件趋势图820,可以看出房颤事件分布、发生规律可能是完全不同的(例如,多个时间段的房颤负荷都是50%,通过观察房颤事件趋势图820,可能可以看到有的时间段内房颤都发生在前半小时、有的时间段内房颤都发生在后半小时、有的时间段内房颤均匀地发生等等)。房颤事件趋势图820和房颤负荷图830综合呈现出来的这些信息,对医护人员来说具有临床意义,对于医生分辨患者的房颤类型是阵发性、持续性还是永久性房颤等也有帮助。
而至少一项所述生命体征参数的趋势图810和房颤负荷图830同时显示,也便于联合呈现预设房颤监测期内任意一个或多个时间段内房颤负荷的大小和/或房颤负荷随时间的变化趋势对至少一项所述生命体征参数所产生的影响。可通过比较生命体征参数和房颤负荷的变化趋势,来判断房颤负荷是否对生命体征参数有影响。例如,房颤负荷图830和心率的趋势图810联合呈现,医生可以去看房颤负荷高低对于心室率的影响,看高心率是否与房颤负荷高低是相关的,如果相关性一般,医生直接开一些控制心室率的药物即可;如果非常相关,而患者心室率又比较高,症状比较明显,医生可能会调整药物类型,除了单纯控制心室率外,还会直接进行药物复律,例如使用胺碘酮类药物,使房颤转复为窦性心律,从而彻底控制心室率;此外,医生可能不仅仅是开药,还会下决定去做房颤消融手术,解决源头问题。可见,两者联合呈现有利于医生对患者病情做出准确判断,并采取进一步的措施。
而至少一项所述生命体征参数的趋势图810、房颤事件趋势图820以及房颤负荷图830同时显示,以便于联合呈现预设房颤监测期内房颤事件的发生与否和/或房颤事件的分布情况、房颤负荷的大小和/或房颤负荷随时间的变化趋势对至少一项所述生命体征参数所产生的综合影响。例如,ART是动脉血压,即IBP(有创血压)的一种,是血流动力学参数的一种,通过房颤负荷图830、房颤事件趋势图820和动脉血压(ART)的趋势图,医生可以看房颤负荷多少或房颤发生与否,对于循环系统的血流动力学的影响。
本实施例中,生命体征参数的趋势图810、房颤事件趋势图820以及房颤负荷图830在时间上是对齐的,例如图2所示,三者并列显示,共用时间段(房颤监测期)。当然,也可以显示一时间坐标,生命体征参数的趋势图810、房颤事件趋势图820以及房颤负荷图830三者共用该时间坐标。如此,便于医生直观的比较三者之间的相关性。
图2和图3中的房颤事件趋势图820,是用竖线来表示单次发生的房颤事件,当然图2和图3只是用于举例说明,本发明不限于此,其还可以是用散点、折线、曲线、柱形、或其中至少两者的组合来作为房颤事件趋势图820的元素。例如,可以在趋势图中以点的形式标出每次发生的房颤事件,可选地,还可以用直线将相邻的两点进行连接,以便于更直观地进行观察。特别地,当用点的形式标出多次连续发生的房颤事件时,这些点可能连接成直线或者曲线,通过从整体上观察代表每次房颤事件发生的点,能够知道该房颤事件在一段预设时间内发生的态势。又例如,在图2的实施例中,用长度或高度固定且垂直于时间轴的竖线作为房颤事件趋势图820的元素,代表每次房颤事件,各竖线之间彼此平行。竖线沿着时间轴方向的宽度用于表示单次房颤事件发生的时长。因此,若有一次或多次连续发生的房颤事件时,原本的竖线可能呈现为沿着时间轴推移的色块,色块沿时间轴方向的宽度越大,则表明该次房颤事件持续的时长越长。如图3所示,房颤事件趋势图820中,822区域中相对孤立的竖线表明单个房颤事件发生时间短、各个房颤事件之间无规律;821区域中相对连续的竖线表明单个房颤事件发生时间短、发生的间隔较近;823区域中为一色块,表明单个房颤事件持续时间较长,或多个房颤事件间隔非常短以至于图中显示不出来间隔。可见房颤事件趋势图820不仅能呈现整个房颤监测期内房颤事件整体上的趋势、态势,而且还能呈现不同时间段房颤事件的发生频率、持续时间等特点,据此医生能较为快速的判断患者的房颤类型,房颤类型通常有首诊房颤、阵发性房颤、持续性房颤、长程持续性房颤、永久性房颤等。
类似的,生命体征参数的趋势图810也可以用上述各种元素来呈现生命体征参数的趋势,在此不做赘述。通过生命体征参数的趋势图810、房颤事件趋势图820等各类趋势图,可以一目了然、非常轻松简单地观察一段预设时间内待观测变量(如房颤事件、生命体征参数等)的发展趋势。
具体的,房颤分析单元220在房颤事件趋势图820上,通过预设的第一标识对房颤事件的发生时刻进行标记,以区分发生房颤事件和未发生房颤事件的时刻。例如,图2所示的实施例中,以横坐标为时间轴,每次发生房颤事件时,在横坐标上对应的时刻用固定长度的直线进行标记,而无房颤事件发生的时刻则不进行任何标记。因此,当从整体上观察一段时间内的房颤事件趋势图820,可以通过线条的疏密程度和分布程度,来一定程度了解该时间内房颤事件发生的情况,例如,房颤连续发生、间隔性地发生等等,非常直观。
房颤分析单元220在通过显示器30显示至少一项所述生命体征参数(本实施例中为获取了监护数据的所有生命体征参数)的趋势图810和房颤事件趋势图820时,用预设的标识关联房颤事件趋势图820中的房颤事件和至少一项所述生命体征参数的趋势图810中的生命体征参数。预设的标识可以有多种方式,例如各种图形、图案、颜色等,图2和图3所示的预设标识为虚线,图10所示的预设标识为色块D,只要能突出将房颤事件与生命体征参数关联起来即可。从图2和图10可知,医生横向查看趋势图可以看到房颤事件、生命体征参数的变化趋势,不用反复对照生命体征参数的趋势图810和房颤事件趋势图820也能通过预设的标识查看房颤事件和生命体征参数之间的相关性。
在一些实施例中,房颤分析单元220对至少一项所述生命体征参数(本实施例中为获取了监护数据的所有生命体征参数)的趋势图810上处于发生房颤事件的时刻或时间段内的部分进行标记,如此,医生在观察生命体征参数的趋势时,无需查看房颤事件趋势图也能判断生命体征参数与房颤事件的相关性,非常方便。标记可以有多种方式,例如用各种图形、图案、颜色等进行标记,只要能突出显示发生房颤事件的时刻或时间段即可。
房颤分析单元220还对所述至少两项生命体征参数的监护数据进行处理,识别预设房颤监测期内所述至少两项生命体征参数的最值和/或其发生时刻;本实施例中,即识别各项生命体征参数的最值,也对应识别最值的发生时刻。最值可以是最大值,也可以是最小值,本实施例中,最值包括最大值和最小值。
房颤分析单元220在通过显示器显示所述至少两项生命体征参数的趋势图810时,还呈现所述至少两项生命体征参数的所述最值和/或其发生时刻。最值和/或其发生时刻有多种方式呈现,例如,仅显示最值和/或其发生时刻的数值,又例如,仅在趋势图上标记最值发生的位置(时刻),当然,也可以即显示最值和/或其发生时刻的数值,又在最值发生的位置做标记。本实施例中,在各个生命体征参数的趋势图810上呈现最大值及其发生时刻、最小值及其发生时刻。呈现最值有多种方式,例如用各种图形、文字、图案、颜色等进行标记,若房颤综合视图中设置有时间坐标,则标记了最值也就相当于标记了其发生时刻。本实施例中,伴随有房颤的最值和无房颤的最值差异化显示,例如,房颤分析单元220通过显示器突出显示有房颤伴随发生的最值和/或其最值发生时刻,可以用颜色、亮度等进行突出显示。又例如,房颤分析单元220通过显示器用预设的第一标识或文字显示有房颤伴随发生的最值和/或其最值发生时刻,通过显示器用预设的第二标识或文字显示没有房颤伴随发生的最值和/或其发生时刻。第一标识和第二标识可以是各种图形、图案等,两者不同即可,当然,较佳的,第一标识较第二标识醒目。图2中第一标识为具有填充色的三角箭头,第二标识为无填充色的三角箭头。如此,医生不仅能快速找到最值,还能快速的找到哪些最值伴随有房颤,非常方便。
生命体征参数的趋势图810可以是曲线图、直方图、条形图、箱线图、散点图、折线图中的一种,也可以是曲线图、直方图、条形图、箱线图、散点图、折线图中多种的组合。如图2所示,本实施例以曲线图为例进行说明。
有些实施例中,如图10所示,生命体征参数中包括心率HR和脉率PR,心率的趋势图和脉率的趋势图还共用表示生命体征参数的数值大小的纵坐标,图10中,心率曲线E和脉率曲线F共用横坐标、纵坐标。房颤患者经常出现心率、脉率不同步的特点,心率曲线和脉率曲线叠加显示,这两条曲线的重合度在一定程度上揭示了房颤患者的症状轻重,有利于医生及早发现房颤患者的病情进展。
有些实施例中,生命体征参数中包括收缩压、舒张压、平均压中的至少两个,其趋势图还共用表示生命体征参数的数值大小的纵坐标。图10中,生命体征参数中包括收缩压、舒张压和平均压,三者的趋势图分别是G、I和H,三者共用横坐标(时间)和纵坐标(数值大小)。
房颤分析单元220还可以通过显示器用不同的颜色区分显示共用纵坐标的生命体征参数的趋势图。例如,图2中的心率曲线E和脉率曲线F用不同的颜色区分。房颤分析单元220也可以通过显示器用不同的线型(例如粗实线、细实线、各类虚线、点画线等)区分显示共用纵坐标的生命体征参数的趋势图。例如,图10中收缩压曲线G和舒张压曲线I用实线,平均压曲线H用虚线区分等。如此可以更容易的分辨共用纵坐标的各个曲线。
房颤综合视图中还包括:房颤统计信息、生命体征参数统计信息、典型事件统计信息、典型波形信息中的至少一个,如图2所示,本实施例包括上述四种。房颤分析单元对预设房颤监测期内房颤相关的信息做统计,得到房颤统计信息。房颤统计信息可以以文字、图表等形式呈现,本实施例中,以房颤统计图表的形式呈现,见图2的信息统计区。其中,房颤统计信息包括以下至少一个:预设房颤监测期内房颤总发生次数、预设房颤监测期内房颤总持续时间、预设房颤监测期内房颤总负荷、预设房颤监测期内的至少一个预设时间段内的房颤发生次数、预设房颤监测期内的至少一个预设时间段内的房颤持续时间、预设房颤监测期内的至少一个预设时间段内的房颤负荷、预设房颤监测期内房颤持续时间分段统计信息。医生通过房颤统计信息可以准确、详细的了解患者在房颤监测期内的房颤情况,非常方便。
房颤分析单元对预设房颤监测期内生命体征参数的监护数据做统计,得到生命体征参数统计信息。生命体征参数统计信息包括以下至少一个:至少一个生命体征参数的最值及发生时刻、平均值、分段统计信息。同样的,生命体征参数统计信息可以以文字、图表等形式呈现,图2显示的是预设房颤监测期内的心率统计图表。
房颤分析单元对预设房颤监测期内的典型事件做统计,得到典型事件统计信息。典型事件统计信息包括以下至少一个:房颤伴快速心室率次数、房颤伴RR长间歇次数、极度心动过速次数、极度心动过缓次数、首发房颤时刻、最大心率房颤时刻、持续时间最长房颤发生时段。典型事件通常是医生重点关注的事件,具有临床意义。房颤综合视图还可以包括预设房颤监测期内的报警事件统计图表,报警事件统计图表可以反映出监护系统在监护患者过程中产生的各种报警,当然,也包括房颤报警,报警事件也属于典型事件,报警事件统计图表也可以作为典型事件统计信息中的一部分,显示在图2的信息统计区。
房颤分析单元对心电信号的监护数据进行处理,得到典型波形信息。典型波形信息包括以下至少一种波形的至少一个片段:患者首发房颤的心电波形、预设房颤监测期内包含心率最高值的一段心电波形、预设房颤监测期内包含心率最低值的一段心电波形、以及预设房颤监测期内持续时间段最长的房颤对应的心电波形。典型波形信息可以呈现给医生一段典型的心电波形,具有临床意义。
具体统计哪些房颤统计信息、生命体征参数统计信息、典型波形信息以及典型事件统计信息,可以在房颤配置单元中进行设置,也可以采用系统的默认设置。
房颤分析单元220还用于根据用户在房颤综合视图上的操作确定所述操作所选择的目标时间段,并通过显示器显示目标时间段内的心电波形。例如,各个生命体征参数的趋势图在横向(时间)上是可选定的,用户通过输入装置将光标移动到极值位置,或者点击极值位置,则显示该极值前后一段时间的心电波形。目标时间段内的心电波形可以作为典型波形信息显示在典型波形区,当然,也可以显示在其他区域。可见,用户基于趋势图的操作能与典型波形信息联动显示,在有限的显示界面上能显示大量的信息。
一些实施例中,生命体征参数趋势图包括心率趋势图,预设房颤监测期包括多个最小单位时间段,如图11所示,房颤负荷图830中每个条形块对应的时间段为一个最小单位时间段。房颤分析单元220响应于用户选择目标分时段的操作,通过显示器进一步显示房颤分时段视图840。用户选择目标分时段可以有多种形式,例如,通过输入装置直接输入目标分时段,也可以通过输入装置在生命体征参数的趋势图810、房颤事件趋势图820或房颤负荷图830上选择目标分时段。目标分时段可以为所述多个最小单位时间段中的任一个,如图11和图12所示,用户操作输入装置在房颤负荷图830上点击,点击的位置对应的最小单位时间段为目标分时段,当然,目标分时段也可以包括连续的多个最小单位时间段,用户可以操作输入装置在房颤负荷图830上滑动选择一段距离,这段距离对应的多个最小单位时间段为目标分时段;可见,用户可以在查看房颤综合视图时选取自己感兴趣的时间段从而呈现房颤分时段视图840,信息显示非常快捷。如图11所示,房颤分时段视图840可以显示在房颤综合视图周围,也可以作为浮动窗口显示在房颤综合视图上,当然,还可以在一个单独的显示界面进行显示等。
房颤分时段视图840中包括:目标分时段内的心率趋势图841、心率统计信息842和典型心率事件统计信息中的至少一个。可见医生可以看到其感兴趣的一个时间段内心率的详细信息,有利于医生研判患者的病情。心率统计信息842可以以附图的形式呈现,如图11和图12所示,当然,也可以以文字或列表的形式呈现。房颤分时段视图840中还包括目标分时段内的房颤统计信息和房颤典型事件统计信息中的至少一个。可见,房颤分时段视图840相当于房颤综合视图的一个局部视图,医生可以在目标分时段内看到心率、房颤的综合信息,便于准确的研判患者的病情。
生命体征参数趋势图还可以包括目标数值标识,目标数值标识用于标识生命体征参数的目标数值,目标数值可以系统预设,也可以由用户设置和修改。以心率趋势图为例,如图2所示,心率趋势图的目标数值标识为目标心率标识,目标心率标识用于标识预设的目标心率。目标心率可以系统预设,也可以由用户设置和修改。目标心率可以是心率的上限,也可以是心率的下限,还可以包括心率的上限和下限,对应的,目标心率上限可以是上限标识、下限标识或者包括上限标识和下限标识。目标心率标识可以是文字、符号、图形和图案等。图2中目标心率标识为目标心率对应的标示线,医生根据目标心率标识可直观的看出患者的心率是否达标,非常方便。
对应的,心率趋势图841不仅包括目标分时段内的心率曲线,还包括目标心率标识。图11和图12中,目标心率标识有两个:目标线1和目标线2,从图中可一眼看出患者的心率在目标分时段内是超过了目标心率的,提示效果好。
处理器还可以根据房颤事件的信息和各项生命体征参数的监护数据,生成包含有房颤综合视图等信息的概览报告,可以将概览报告(电子版)显示输出给其他设备,也可以控制处理器连接的打印设备将概览报告打印出来。甚至于在有些实施例中,可不显示概览报告、房颤综合视图等,而是采用输出电子版的概览报告或通过打印设备打印纸质的概览报告等方式,来给医生提供上述的房颤综合视图。
上述实施例中,监护系统的信号采集器获取的是至少两项生命体征参数的监护数据,本实施例中,信号采集器也可以只获取心电参数的监护数据。具体的,本发明还提供一种显示监护数据的方法,如图13所示,包括如下步骤:
步骤1’、房颤分析单元220根据房颤配置单元210的参数配置,通过信号采集器10获取患者的至少一项生命体征参数的监护数据,所述至少一项生命体征参数中包括心电参数,即,图13所示的实施例中,可以只获取心电参数的监护数据,也可以获取包括心电参数在内的多项生命体征参数的监护数据,除此之外本步骤与上述实施例的步骤1相同,在此不做赘述。
步骤2’、获取患者发生的房颤事件的信息,本步骤与上述实施例的步骤2相同,在此不做赘述。
步骤3’、房颤分析单元220根据获取的房颤事件的信息和所述至少一项生命体征参数的监护数据,显示房颤综合分析界面,如图2所示。房颤综合分析界面包括参数趋势区和/或信息统计区。
其中,参数趋势区显示所述至少一项生命体征参数的趋势图810,参数趋势区还显示房颤事件趋势图820和房颤负荷图830中的至少一个。本实施例以参数趋势区还显示房颤事件趋势图820和房颤负荷图830这两者为例进行说明。所述至少一项生命体征参数的趋势图、房颤事件趋势图以及房颤负荷图同时显示,以便于联合呈现所述预设房颤监测期内任意一个或多个时刻或时间段内至少一项所述生命体征参数、所述患者发生的房颤事件以及房颤负荷中至少两者之间的相关性。其中参数趋势区显示的具体内容已在上述实施例中详细阐述,在此不做赘述。
信息统计区显示以下至少之一:房颤统计信息、所述至少一项生命体征参数统计信息、典型事件统计信息。其中信息统计区显示的具体内容也已在上述实施例中详细阐述,在此不做赘述。
房颤综合分析界面还包括典型波形区,典型波形区内显示有典型波形信息,典型波形信息的具体内容也已在上述实施例中详细阐述,在此不做赘述。
如图2所示,房颤综合分析界面主要呈现参数趋势区,信息统计区和/或典型波形区可以设置在参数趋势区周边,当然,信息统计区和/或典型波形区也可以隐藏,在用户某项操作(例如将光标移出参数趋势区)的触发下呈现信息统计区和/或典型波形区。
综上,本发明提供的监护系统和显示监护数据的方法、房颤综合管理的方法等,通过房颤综合视图(AF View)的设计将房颤事件报警、房颤负荷和生命体征参数等信息联合呈现,不仅能定性、定量的呈现房颤相关的信息,而且还能反映出房颤与生命体征参数的相关性,同时集中呈现病人监测周期内的房颤事件分布等统计数据,为医护人员系统评估患者的生理病理状态提供帮助,便于医护人员更加系统和精细地评估患者一段时间内的房颤变化状态,提高了患者房颤相关数据展示的效率,也提高了医生对患者的房颤进行干预的效率。
