Point-of-care ultrasonography (POCUS) is a widely used tool in emergency and critical care settings, useful in the decision-making process as well as in interventional guidance. Following some rules in technique and interpretation, and always integrating POCUS findings into the broader clinical context, most POCUS misdiagnosis can be avoided, and thus patients’ safety can be enhanced. Being aware of a list of common pitfalls may help... Read More | Comment

We develop an algorithm that can detect pneumonia from chest X-rays at a level exceeding practicing radiologists. Our algorithm, CheXNet, is a 121-layer convolutional neural network trained on ChestX-ray14, currently the largest publicly available chest X-ray dataset, containing over 100,000 frontal-view X-ray images with 14 diseases. Four practicing academic radiologists annotate a test set, on which we compare the performance of CheXNet to that of... Read More | Comment

With the birth of “fluid responsiveness” physiology, there has been a slow and solemn drumbeat ushering the central venous pressure (CVP) up the squeaking planks of the hemodynamic gallows. Despite this, a few years ago I made a humble defense of the central venous pressure. Importantly, I was not proposing the CVP as a marker of fluid responsiveness or volume status; instead, I aimed to... Read More | Comment

This book contains all the information that readers will require in order to perform echocardiography and to interpret the findings correctly. After an introductory chapter on the essential physics of ultrasonography, standard echocardiographic examination via both the transthoracic and the transesophageal approach is described. In the third section, the functional anatomy of all normal and pathologic thoracic structures as observed on echocardiography is presented in... Read More | Comment

FDA just cleared Butterfly Network’s iQ an iPhone-connected Ultrasound system, which claims it is the world’s first “ultrasound-on-a-chip” system. Butterfly iQ is FDA 510(k) cleared for diagnostic imaging across 13 clinical applications which span the whole body: Abdominal, Cardiac Adult, Cardiac Pediatric, Fetal/Obstetric, Gynecological, Musculo-Skeletal (Conventional), Musculo-Skeletal (Superficial), Pediatric, Peripheral Vessel, Procedural Guidance, Small Organ and Urology. Butterfly iQ will begin shipping to customers in... Read More | Comment

Point-of-care ultrasonography (POCUS) can augment physical examination and procedural efficacy but requires appropriate education and program setup. As POCUS continues to spread, internal medicine physicians need to clarify how they intend to use this technology. Equipment is now increasingly accessible, but programs need to determine how to allocate time and resources to training, clinical use, and quality assurance. Programs that develop robust implementation processes that... Read More | Comment

Lung ultrasonography can be rapidly performed in the majority of patients with MET activation for respiratory deterioration. As an independent diagnostic test, lung ultrasonography is non-inferior to the medical emergency team (MET) clinical assessment and may prevent unnecessary treatments if used simultaneously. The ultrasound exam was completed in 49/50 (98%) patients enrolled in the study with a mean duration of 13 ± 4 min. When excluding six cases... Read More | Comment

The aim of this study was to test the hypothesis that the right ventricle is more dilated during resuscitation from cardiac arrest caused by pulmonary embolism, compared with hypoxia and primary arrhythmia. The right ventricle was more dilated during resuscitation when cardiac arrest was caused by pulmonary embolism compared with hypoxia and primary arrhythmia. However, the right ventricle was dilated, irrespective of the cause of... Read More | Comment

CCUS combining CCE and chest ultrasonography rapidly provides valuable information in patients presenting with ARF. A pragmatic and systematic applied protocol may first evaluate how aerated is the lung and whether there is pulmonary edema. CCE helps the physician in identifying the cause of poor lung aeration or lung edema, and in assessing LV filling pressure and ventricular function. Read More | Comment
