Heparin-induced thrombocytopenia paradoxically is a transient pro-thrombotic disorder triggered by heparin exposure. If not treated appropriately, it can be life threatening because of its related thromboembolic complications. In particular, it presents a unique challenge in patients needing extracorporeal life support, because anticoagulation is essential(More)
This paper presents the results of two cognitive load studies comparing three augmented reality display technologies: spatial augmented reality, the optical see-through Microsoft HoloLens, and the video see-through Samsung Gear VR. In particular, the two experiments focused on isolating the cognitive load cost of receiving instructions for a button-pressing(More)
BACKGROUND High-risk percutaneous coronary interventions (PCI), refractory cardiogenic shock and in-lab cardiac arrest are all associated with significant mortality. Percutaneous left ventricular assist devices (pLVAD) and CPS (cardiopulmonary support) have been used to support such patients. However, the extent to which the use of these devices can improve(More)
Penetrating wounds to the heart represent a significant surgical challenge because of their unique clinical course and the need for emergent operative care. This operative care, which may include cardiopulmonary bypass (CPB), must be initiated in a prompt yet careful fashion to optimize outcome, while minimizing morbidity. Trauma, because of its(More)
Platelet rich plasma (PRP) is being used with increased frequency in many surgical procedures for its known benefits of accelerated surgical wound site healing. Speculations in its efficacy in the presence of anti-platelet therapy have been proposed. To aid in defining a quality platelet rich plasma product in the presence of acetylsalicylic acid (ASA) and(More)
Heparin-induced thrombocytopenia and its related complications can be life-threatening in patients undergoing cardiopulmonary bypass (CPB) with heparin exposure. While the literature illustrates many different techniques which might be employed in this situation, most are used infrequently. This case report provides an overview of the successful use of(More)
UNLABELLED Concepts of cardiopulmonary support (CPS), extracorporeal membrane oxygenation (ECMO), and ventricular support (VS) have been thoroughly studied and refined. These perfusion adjuncts often require multiple devices, skill sets, and significant financial burden to purchase, maintain, deploy, and use. We describe a novel system that is rapidly(More)
Developing new strategies to improve patient safety and risk reduction is fundamental to hospital and patient success. Currently, there is a tendency in hospital safety management to focus solely on human error rather than organizational and educational causes that contribute to medical accidents. Although health care providers are the primary safety(More)
Embolization of marrow fat appears to be an inevitable consequence of long bone fractures. Pulmonary fat embolism (FE) with cardiovascular collapse is associated with a high mortality rate because of acute right ventricular failure and hypoxia. Immediate and appropriate resuscitation is required to prevent sudden death. Although extracorporeal membrane(More)
