font-family: 宋体, SimSun; word-wrap: break-word !important;">监护仪利用振波法测量NIBP。测量过程中，血液的流动所引起的血管壁搏动将在袖带内产生气体振动波，该振动波通过气管传至机内压力传感器，实时检测袖带压。常见故障有两种：</span></p><p style="margin-bottom: 10px; max-width: 100%;

word-wrap: break-word !important;">①气泵检测：拆下气泵接通12V直流电源，测试气泵工作及出气量是否正常，如不正常，气泵损坏需更换；</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68);

box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">故障分析排除：</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">（1）选择合适大小袖带，并在袖带绑定前，去除体表阻隔物以及挤出袖袋内气体。袖袋过松或过紧，都会使袖带内气体无法正常感受血管壁的搏动产生振动波，导致血压无法测量或测值不准。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">（2）排除病人自身活动的影响。利用振波法测量NIBP，其中最主要的一个缺点就是易受外界振动的干扰，因此，NIBP测量应在平静状态下进行。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">（3）袖带绑定位置和病人姿势应当正确。研究结果表明，NIBP测量的位置和心脏的高度每相差10cm，所测得的血压值会相差约8mmHg。因此，测量NIBP时应保持测量位置与心脏的高度平齐。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">（4）应考虑血压模块故障。该模块中压力传感器或信号处理系统的损坏，都会导致无测量结果或测值不准。此时，需拆机对该模块进行维修或更换。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%;

font-family: 宋体, SimSun; word-wrap: break-word !important;">监护仪测量呼吸大多采用电阻抗法。主要是通过RA和LL两个电极拾取人体胸廓因呼吸阻抗变化而引起的电信号，并经机器系统分析处理，最终得出呼吸频率的过程。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box;

word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; font-size: 16px; word-wrap: break-word !important;">故障现象：无呼吸波形或呼吸波形异常，测量不准。故障分析排除：由RESP的测量原理可知，呼吸信号。</span><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">检测是由ECG电极来完成的，因此与ECG有密不可分的关系。具体应排除以下四种因素的影响：</span></span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 22.4px; word-wrap: break-word !important;"><span style="max-width: 100%; box-sizing: border-box; font-family: 宋体, SimSun; word-wrap: break-word !important;">（1）排除病人频繁活动和剧烈咳嗽的干扰，应在平静状态下测量。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68);

word-wrap: break-word !important;">（2）正确安放电极位置，尤其是RA和LL两电极的位置要安放正确。</span></p><p style="margin-bottom: 10px; max-width: 100%; box-sizing: border-box; min-height: 1em; color: rgb(68, 68, 68); font-family: 微软雅黑, Arial, Helvetica, sans-serif;
