患者状态指数（PSI）是临床验证的麻醉和镇静效果的测量。PSI是在高级伪影剔除后，通过高分辨率4通道脑电图（EEG）监测仪通过专有算法计算的。PSI专门设计用于术中和重症监护，以监测患者镇静和药物效果。该算法依赖于来自大脑前后关系的EEG功率、频率和相位信息以及双侧大脑区域之间的相干性。EEG监测器最初称为PSA4000（R），也是最新一代的设备SEDLine（R）监测器。SEDLine（R）系统为临床医生提供了存储和下载患者数据以备将来使用的选项，以及通过密度谱阵列（DSA）显示器监测双侧大脑功能和对称性。
The patient state index (PSI) is a clinically validated measure of the effect of anaesthesia and sedation. The PSI is calculated via a proprietary algorithm by a high-resolution 4-channel electroencephalograph (EEG) monitor after advanced artifact rejection. The PSI has been designed specifically for intra-operative and intensive care use to monitor patient sedation and drug effect. The algorithm relies on EEG power, frequency and phase information from anterior-posterior relationships of the brain as well as coherence between bilateral brain regions. The EEG monitor, initially called the PSA4000 (R), is also the SEDLine (R) monitor, the newest generation of the device. The SEDLine (R) system provides the clinician the option of storing and downloading patient data for future use as well as monitoring bilateral brain function and symmetry with a density spectral array (DSA) display.
