word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>故障现象：心电波形太大，无法看到整幅波形。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>检查方法：检查心电设置中的心电幅度是否设置太大，使心电波形溢出。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>解决方法：将心电幅度调到合适值，可观察到整幅波形。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p><o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>5 心电受电刀干扰<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>故障现象：在手术中使用电刀，当电刀负极板接触人体时心电出现干扰。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>检查方法：监护仪本身及电刀外壳接地是否良好。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>解决方法：给监护仪和电刀加装良好接地。<o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p><o:p style="max-width: 100%; word-wrap: break-word !important; box-sizing: border-box !important;"></o:p>6 呼吸信号太弱<o:p style="max-width: 100%;
