| 1 | The utility of point-of-care ultrasound in the assessment of volume status in acute and critically ill patients显示文摘BACKGROUND:Volume resuscitation has only been demonstrated to be effective in approximately fifty percent of patients.The remaining patients do not respond to volume resuscitation and may even develop adverse outcomes(such as acute pulmonary edema necessitating endotracheal intubation).We believe that point-of-care ultrasound is an excellent modality by which to adequately predict which patients may benefi t from volume resuscitation.DATA RESOURCES:We performed a search using PubMed,Scopus,and MEDLINE.The following search terms were used:fluid responsiveness,ultrasound,non-invasive,hemodynamic,fluid challenge,and passive leg raise.Preference was given to clinical trials and review articles that were most relevant to the topic of assessing a patient’s cardiovascular ability to respond to intravenous fl uid administration using ultrasound.RESULTS:Point-of-care ultrasound can be easily employed to measure the diameter and collapsibility of various large vessels including the inferior vena cava,common carotid artery,subclavian vein,internal jugular vein,and femoral vein.Such parameters are closely related to dynamic measures of fluid responsiveness and can be used by providers to help guide fluid resuscitation in critically ill patients.CONCLUSION:Ultrasound in combination with passive leg raise is a non-invasive,costand time-effective modality that can be employed to assess volume status and response to fluid resuscitation.Traditionally sonographic studies have focused on the evaluation of large veins such as the inferior vena cava,and internal jugular vein.A number of recently published studies also demonstrate the usefulness of evaluating large arteries to predict volume status. | Ali Pourmand Matthew Pyle David Yamane Kazi Sumon Sarah E.Frasure | 2019 | World Journal of Emergency Medicine2019，10，4： | 18 |
| 2 | Effects of 946-nm thermal shift and broadening on Nd^(3+):YAG laser performance显示文摘Spectroscopic properties of flashlamp pumped Nd3+:YAG laser are studied as a function of temperature in a range from-30?C to 60?C. The spectral width and shift of quasi three-level 946.0-nm inter-Stark emission within the respective intermanifold transitions of4F3/2→4I9/2are investigated. The 946.0-nm line shifts toward the shorter wavelength and broadens. In addition, the threshold power and slope efficiency of the 946.0-nm laser line are quantified with temperature.The lower the temperature, the lower the threshold power is and the higher the slope efficiency of the 946.0-nm laser line is,thus the higher the laser output is. This phenomenon is attributed to the ion-phonon interaction and the thermal population in the ground state. | Seyed Ebrahim Pourmand Ghasem Rezaei | 2015 | Chinese Physics B2015，24，12： | 2 |
