根据预设的触发判断规则，以及获取的监测参数和/或设置参数，判断是否满足预设的参数约束条件；
在判断满足参数约束条件时，控制气体分析模块102执行气体浓度测量操作。
需要说明的是，在本发明的实施例中，控制器104按照条件测量模式，获取监测参数和/或设置参数。监测参数可以为氧浓度、气道压力、吸气时间、呼气时间、吸呼比、呼气末正压、呼吸流速、血氧、脉率、心率，以及血压中的一种或者多种。设置参数可以为通气控制参数，用户设置的用于确定判断规则的参数阈值、参数异常持续时间等中的一个或者多个。通气控制参数可以包括通气压力、通气氧浓度、呼气末压力、吸气时间、呼吸频率等中的一个或多个。例如，当通气压力、通气氧浓度或呼气末压力、呼吸频率中的一个或多个设置较低或较高，或者当吸气时间设置较短或过 长，就可以设置后续定时等启动气体浓度测量操作，以避免通气过量或通气不足，造成患者发生CO2潴留、高碳酸血症、低碳酸血症等。参数阈值可以包括监测参数阈值和通气控制参数阈值，监测参数阈值对应各所选监测参数，通过监测参数阈值可以判断对应参数是否异常；通气控制参数阈值对应各通气控制参数，通过通气控制参数阈值可以确定触发判断规则。参数异常持续时间定义对应参数监测值超阈值的持续时长或次数等。用户还可以选择设置通气监测参数或控制参数超出阈值的持续时间，即监测参数或设置参数超出阈值后可以立即触发测量，也可以在监测参数或设置参数超出阈值后，持续预设的时间后，再触发测量。具体的预设频率可以根据实际测量需求设置，本发明实施例不作限定。
当然，对于通过监测参数判断是否满足测量触发条件的情况，控制器104可以按照预设频率获取监测参数，以进行是否满足预设测量触发条件的判断。对于通过通气控制参数判断是否满足测量触发条件的情况，控制器104可以在某个通气控制参数设置或更新后，根据该通气控制参数的最新值和对应的通气控制参数阈值设置或修改预设的触发判断规则，后续即根据该触发判断规则判断是否满足参数测量条件。例如，当通气压力由8cm水修改为5cm水后，控制器104可以将触发判断规则由每2小时启动一次修改为每小时启动一次。
需要说明的是，在本发明的实施例中，预设触发判断规则可以为判断获取监测参数和/或设置参数是否达到一定水平或者处于一定范围内。如果监测参数和/或设置参数达到一定水平或者处于一定范围内，则判定满足参数约束条件。如果监测参数和/或设置参数未达到一定水平且未处于一定范围内，则判定不满足参数约束条件。具体的触发判断规则本发明实施例不作限定。
示例性的，在本发明的实施例中，在开启条件测量模式之后，控制器104可以获取一次气道压力。如果控制器104获取到的气道压力的具体值处 于预设区间内，则判定满足参数约束条件，并在每次判定满足时控制气体分析模块102执行一次气体浓度测量操作。
在本发明的实施例中，控制器104在控制气体分析模块102执行气体浓度测量操作之前，还可以输出测量提示信息。
需要说明的是，在本发明的实施例中，测量提示信息用于提示用户是否同意当前控制器104控制气体分析模块102执行气体浓度操作。例如，控制器104输出的测量提示信息为文字“当前是否执行气体浓度操作”，从而在通气设备上显示该段文字，对用户进行提示。具体的测量提示信息本发明实施例不作限定。
在本发明的实施例中，在控制器104输出测量提示信息之后，控制执行气体分析模块102执行气体浓度测量操作之前，还可以执行以下步骤：检测是否接收到测量确认信息；如果接收到测量确认信息，则触发气体分析模块102执行气体浓度测量操作。
可以理解的是，在本发明的实施例中，控制器104输出了测量提示信息以提示用户当前是否执行气体浓度测量操作。相应的，用户需要通过按钮、触控屏等交互工具将是否执行气体浓度测量操作的信息发送给控制器104。如果控制器104检测到接收了测量确认信息，即表明用户同意当前执行气体浓度测量操作，从而触发气体分析模块102执行气体浓度测量操作。
需要说明的是，在本发明的实施例中，控制器104在控制气体分析模块102执行气体浓度测量操作之前，需要控制通气设备的送气流速减小或停止预设抑制通气时长。
可以理解的是，在本发明的实施例中，气体分析模块102执行气体浓度测量操作的过程中，如果通气设备保持原有的送气流速进行送气，新鲜气体将对气体采样接口采集101的目标气体样本产生稀释，从而影响气体分析模块102测量的准确性。因此，在气体分析模块102执行气体浓度测量操作之前，控制器104通过控制通气设备的送气流速减小或者停止预设 抑制通气时长，即可有效避免目标气体样本被新鲜气体稀释，从而气体分析模块102可以测量出准确的目标气体浓度。
在具体实现时，控制器104可以从检测到从预设时刻起经过目标时长，才认为满足测量触发条件，以开启目标气体浓度测量。在从预设时刻起经过目标时长这段时间，控制器104可以通过控制通气设备的送气流速减小或者停止以进行抑制通气，这样能在开启目标气体浓度测量时检测到更准确的目标气体浓度。
在本发明的实施例中，控制器104在控制通气设备的送气流速减小或停止预设抑制通气时长之前，还包括：接收通气抑制时长设置指令；根据通气抑制时长设置指令设置预设抑制通气时长。
需要说明的是，在本发明的实施例中，气体测量装置还可以包括接收模块，控制器104具体可以通过接收模块接收通气抑制时长设置指令。根据通气抑制时长设置指令设置预设抑制通气时长，包括新增、修改，或者关闭预设抑制通气时长中的任意一种。如果通气抑制时长设置指令指示将预设通气抑制时长设置为0，即为关闭抑制通气。当然，在抑制通气过程中，还可以将预设通气抑制时长修改为0，以实现手动提前结束抑制通气。手动提前结束抑制通气后，可以随即执行气体浓度测量操作。具体的预设抑制通气时长本发明实施例不作限定。
在本发明的实施例中，在控制器104控制气体分析模块102执行气体浓度测量操作之前，还包括：输出通气抑制提示信息、建议措施信息，以及设置项提示信息中的一个或多个。
可以理解的是，在本发明的实施例中，在气体分析模块102执行气体浓度操作之前，需要控制通气设备的送气流速减小或者抑制通气设备通气。因此，控制器104可以预先输出相应的通气抑制提示信息、建议措施信息，以及设置项提示信息中的一个或多个，保证医护人员获知相关信息，一旦患者出现不适或者其它症状，可以及时执行相应的医疗操作。
需要说明的是，在本发明的实施例中，通气抑制提示信息具体可以为用于提示通气设备将处于通气抑制状态的文字或者图案等。建议措施信息具体可以为针对通气设备处于通气状态下，患者需要避免执行的一些动作等信息。设置项提示信息具体可以为设置的通气抑制时长，以及各种测量设置项的功能提示信息。具体的通气抑制提示信息、建议措施信息，以及设置项提示信息本发明实施例不作限定。
示例性的，在本发明的实施例中，控制器104输出的通气抑制提示信息为“测量期间暂停通气”，建议措施信息为“尽量避免张口呼吸”，设置项提示信息为“暂停通气时长为S秒”。
在本发明的实施例中，控制器104在测量出目标气体浓度之后，还包括：获取目标测量模式对应的目标标识；基于目标标识，按照预设输出方式输出目标气体浓度。
需要说明的是，在本发明的实施例中，目标标识即在控制器104按照预设输出方式输出目标气体浓度时，可以表征采用的目标测量模式的具体标识。
需要说明的是，在本发明的实施例中，目标标识不限于特定的图形、颜色，以及文字或者字母字符等。例如，目标测量模式为定时测量模式，定时测量模式对应的目标标识为红色，则在按照实时波形方式输出以定时测量模式测量到的目标气体浓度时，对应的波形曲线的颜色为红色。具体的目标标识可以根据实际需求预先设置，本发明实施例不作限定。
需要说明的是，在本发明的实施例中，预设输出方式包括数值方式、实时波形方式、压缩波形方式、拼接波形方式、对比波形方式，以及图表方式中的一个或多个。其中，图表方式可以为曲线图、直方图、趋势图、饼图、柱状图，以及蛛网图中的任意一种。压缩波形方式可以包括全压缩波形方式和局部压缩波形方式。此外，在按照预设输出方式输出的图像中还可以记录测量时间和测量次数等与测量相关的元素，使图像信息更加丰 富。当然，预设输出方式还可以包括其它类型的方式，具体的预设输出方式本发明实施例不作限定。
图5(a)为本发明实施例提供的一种示例性的目标气体浓度的输出示意图一。如图5(a)所示，目标采样气体实际上为CO 2，对应的目标气体浓度即为CO 2浓度，控制器104按照实时波形方式，根据气体分析模块102测量得到的CO 2浓度输出CO 2实时波形。
图5(b)为本发明实施例提供的一种示例性的目标气体浓度的输出示意图二。如图5(b)所示，目标采样气体实际上为CO 2，对应的目标气体浓度即为CO 2浓度。控制器104按照局部压缩波形方式，对未测量CO 2浓度，即无CO 2浓度的区间进行压缩输出，对测量出CO 2浓度的区间维持正常标准进行波形输出。
示例性的，在本发明的实施例中，目标测量模式为定时测量模式，相应的目标标识为圆点，在按照曲线图输出目标气体浓度值时，以圆点在曲线图中标识目标气体浓度值。目标测量模式为条件测量模式，相应的目标标识为方形，在按照曲线图输出目标气体浓度值时，以方形在曲线图中标识目标气体浓度值。
图5(c)为本发明实施例提供的一种示例性的目标气体浓度的输出示意图三。如图5(c)所示，目标采样气体实际上为CO 2，对应的目标气体浓度即为CO 2浓度，预设输出方式为趋势图方式。可以明显看到，目标测量模式为条件测量模式，其对应的目标标识为正方形，目标测量模式为第一等间隔测量模式，其对应的目标标识为圆形，目标测量模式为定时测量模式，其对应的目标标识为三角形。如图5(c)所示，不同测量模式下测量到CO 2浓度在图中以对应的目标标识进行标记。
在本发明的实施例中，控制器104在执行按照预设输出方式输出所述目标气体浓度的步骤时，还包括：按照预设标记方式标记预设气体浓度阈值。
可以理解的是，在本发明的实施例中，在上述基于目标标识，按照预设输出方式输出目标气体浓度时，只体现了目标测量模式。在实际应用过程中，还可以在输出目标气体浓度时，标记预设气体浓度阈值，以体现测量出的目标气体浓度和预设气体浓度阈值的大小关系。医护人员在查看到目标气体浓度和预设气体浓度阈值之间的大小关系时，可以采取相应的医疗措施等。
需要说明的是，在本发明的实施例中，预设气体浓度阈值可以包括最大阈值和最小阈值，均可进行标记。具体的预设气体浓度阈值本发明实施例不作限定。
图6为本发明实施例提供的一种示例性的设置预设气体浓度阈值的示意图。如图6所示，预设气体浓度阈值包括最大阈值和最小阈值，用户可以通过选择工具点击或者拖动最大阈值和最小阈值之后对应的图标，使图标中的圆圈靠向右侧，即开启设置，之后输入相应的阈值，即50mmHg和15mmHg，完成设置。
需要说明的是，在本发明的实施例中，预设标记方式包括参考线方式、刻度方式、颜色方式，以及数值闪烁方式中的一个或多个。当然，预设标记方式还可以用户自定义的其他标记方式，本发明实施例不作限定。
具体的，如图5(c)所示，控制器104按照实时波形方式输出目标气体浓度时，以参考线的方式在波形中标记出预设气体浓度阈值中包括的最大阈值和最小阈值。在图5(c)的波形中，标记了多个时刻下测量到的多个目标气体浓度值，可以直观的看到各个时刻的目标气体浓度值是否超过预设气体浓度阈值。
在本发明的实施例中，控制器104在执行开启目标测量模式的步骤之后，还包括：输出目标测量模式和/或输出测量状态。
需要说明的是，在本发明的实施例中，可以在开启目标测量模式之后，输出目标测量模式。目标测量模式可以为定时测量模式、第一等间隔测量 模式、第二等间隔测量模式、第一非等间隔测量模式、第二非等间隔测量模式，以及条件测量模式中的任意一种。
需要说明的是，在本发明的实施例中，测量状态具体可以包括气体浓度测量开启、测量即将开始、测量进行中，以及测量已结束等状态。具体的测量状态本发明实施例不作限定。
图7为本发明实施例提供的一种示例性的开启状态提示示意图。如图7所示，控制器104执行开启目标测量模式，具体的目标测量模式为第一等间隔测量模式。控制器104在按照压缩波形方式输出CO2浓度时，输出第一等间隔测量模式对应的图标和测量状态的相关文字“测量开启”，在波形图右上角进行显示。
示例性的，在本发明的实施例中，控制器104在执行按照目标测量模式控制气体分析模块102执行气体浓度测量操作的步骤时，可以按照文字提示方式，在测量开始前10秒输出文字“测量即将开始”，在测量进行中输出文字“测量进行中”，在测量结束时输出文字“测量已结束”。
本发明实施例提供了一种气体测量方法，应用于为患者提供呼吸支持的通气设备，在通气设备进行通气的过程中，如果接收到测量触发指令或检测到满足预设的测量触发条件，则开启目标测量模式；按照目标测量模式执行气体浓度测量操作，测量出目标气体浓度。本发明实施例提供的技术方案，能够在对病人进行通气时，按照不同模式执行气体浓度测量操作，以测量病人呼出气体中目标气体浓度，测量方式简单且灵活。
