By searching recent related researches about ultrasound pulmonary assessment in intensive care unit (ICU) patients and chest physiotherapy domestically and abroad, it reviewed the nursing progress of chest physiotherapy effect evaluation, the overview of lung ultrasound, the application of critical ultrasound in chest physiotherapy, ultrasound guided target chest physiotherapy and the feasibility of nurses' applying ultrasound, in order to provide reference for critical medical staff.

This article reviews the application of critical ultrasonography in nursing assessment of ICU patients. It summarized the application of critical ultrasonography in hemodynamic assessment, lung assessment, gastric residual monitoring, thrombosis screening, stress injury assessment, bladder scan and education of ICU patients, and prospected its application in nursing assessment of ICU patients. It aims to guide nurses to carry out goal-oriented nursing, help explore a new vision of critical care, improve the quality of nursing.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.
