■超声心输出量监测仪(USCOM),监测患者血液动力学状态演变并确定休克类型的仪器,已成为评估心脏病病理和预测疾病变化的重要工具,但是对于不同的患者身体状况,仪器发现有一些差异。本文根据临床特征和测试参数,研究了在不同类型的重症患者中测量的USCOM波形质量是否存在差异。
■基线数据,诊断,超声心动图,通风模式,和USCOM结果是回顾性收集急诊重症监护病房患者的。使用Fremantle评分对波形质量进行量化,以确定年龄的程度,体重指数(BMI),慢性阻塞性肺疾病(COPD),呼吸衰竭,心脏扩大,心脏瓣膜病,通气模式影响USCOM波形质量。
■年龄,身体质量指数,慢性阻塞性肺疾病,呼吸衰竭,左右心脏扩大,主动脉瓣疾病(不包括主动脉瓣狭窄),通气模式对危重症患者USCOM波形质量无明显影响(P>0.05)。
■危重病人的各种身体状况可能对USCOM波形质量的影响有限,可能使USCOM适用于ICU入院期间的血流动力学状态的早期评估。
UNASSIGNED: The ultrasonic cardiac output monitor (USCOM), an instrument that monitors the evolution of a patient\'s hemodynamic status and determines the type of shock, has become an important tool for assessing cardiac pathology and predicting changes in disease, but there are some variations in the instrumental findings for different physical conditions of patients. This article examines whether there are differences in the quality of USCOM waveforms measured in different types of critically ill patients based on clinical characteristics and test parameters.
UNASSIGNED: Baseline data, diagnoses, echocardiograms, ventilation patterns, and USCOM results were retrospectively collected from patients in the emergency intensive care unit. Waveform quality was quantified using the Fremantle score to determine the extent to which age, body mass index (BMI), chronic obstructive pulmonary disease (COPD), respiratory failure, cardiac enlargement, valvular heart disease, and ventilation pattern influenced USCOM waveform quality.
UNASSIGNED: Age, body mass index, chronic obstructive pulmonary disease, respiratory failure, right and left heart enlargement, aortic valve disease (excluding aortic stenosis), and ventilation mode did not have a significant effect on USCOM waveform quality in critically ill patients (P > 0.05).
UNASSIGNED: Various physical conditions of critically ill patients may have limited effect on the quality of the USCOM waveform, potentially rendering USCOM suitable for early assessment of hemodynamic status during ICU admission.
