RESUMEN
Objective:To establish a practical framework for critical ultrasonography to provide a basis for clinical practice.Methods:With reference to domestic and foreign literature, expert interviews and research groups developed a preliminary draft of the practice framework for critical ultrasonography, and conducted two rounds of consultation using the Delphi method.Results:A practical framework for critical ultrasonography was developed, including 5 primary indicators and 20 secondary indicators. In the two rounds of expert consultation, the expert′s positive coefficient was 100% and the authoritative coefficient was 0.836.Conclusions:Expert opinion has good coordination and high authority, which can provide clinical basis for ICU nurses to carry out ultrasound examination.

Objective@#To establish a practical framework for critical ultrasonography to provide a basis for clinical practice.@*Methods@#With reference to domestic and foreign literature, expert interviews and research groups developed a preliminary draft of the practice framework for critical ultrasonography, and conducted two rounds of consultation using the Delphi method.@*Results@#A practical framework for critical ultrasonography was developed, including 5 primary indicators and 20 secondary indicators.

RESUMEN
Objective@#To evaluate the feasibility of ICU nurse-performed lung ultrasound in screening the reason of dyspnea in ICU patients, and to explore the effect on nursing decisions.@*Methods@#ICU nurses trained on lung ultrasound with 16 hours performed point-of-care lung ultrasound in patient with acute respiratory failure to assess the condition of the patient′s lungs and screen for pleural effusion, atelectasis/lung consolidation. Etc; Repeated examinations by ICU physicians accredited by the International Critical Ultrasound Alliance to evaluate the accuracy of ICU nurse interpretation.@*Results@#A total of 510 lung ultrasonographic examinations were performed in 51 patients. Compared with physicians, ICU nurses correctly interpreted 472 ultrasound signs, accounting for 92.53%. ICU nurses found that the sensitivity of the pleural effusion was 86.7%, the specificity was 95.2%, and the diagnostic accuracy rate was 90.2%, and Youden index was 81.9%. The ultrasonography revealed a sensitivity of 92.1% for atelectic/pulmonary consolidation and a specificity of 92.3.%, the diagnostic accuracy rate was 92.2% and Youden index was 84.4%.@*Conclusion@#ICU nurses who have undergone standardized training can correctly interpret lung ultrasound signs and have good diagnostic value for screening of pleural effusions and atelectasis/lung consolidation; they provide the basis for optimization of chest physiotherapy programs.
RESUMEN
A comprehensive literature on the utility of ultrasound guidance for artery catheterization were searched. The research of the literature was divided to three parts:evaluation of radial artery, the process of puncture and the application progress. Ultrasound is a useful adjunct to arterial catheter insertion and increase the rate of success. During the process of ultrasound guidance, evaluation of radial artery, preparation, the way of poke and the direction of the needle were recommended.
