OBJECTIVE Continuous invasive blood pressure (BP) and heart rate (HR) monitoring in the emergency department (ED) is valuable in managing critically ill patients. Novel noninvasive finger cuff technology allows this same uninterrupted monitoring for almost any individual. This exploratory study compares ED noninvasive continuous to intermittent measurements(More)
OBJECTIVE Emergency physicians (EPs) estimate the underlying hemodynamics of acutely ill patients and use them to help both diagnose and formulate a treatment plan. This trial compared the EP clinically derived estimates of cardiac output (CO) and systemic vascular resistance (SVR) to those measured noninvasively. METHODS Forty acutely ill emergency(More)
Forty-three patients were examined three months after implantation of a multifocal or bifocal intraocular lens following cataract extraction. With far vision correction, simultaneous bifocal function with far acuity better than 0.5 and near acuity better than Nieden 3 was achieved in 95.4% of these cases. Glare sensitivity was tested with the BAT and(More)
We present a novel, parallelizable algorithm capable of automatically reconstructing and calculating anatomical statistics of cerebral vascular networks embedded in large volumes of Rat Nissl-stained data. In this paper, we report the results of our method using Rattus somatosensory cortical data acquired using Knife-Edge Scanning Microscopy. Our algorithm(More)
Knife-edge scanning microscopy provides the capability to image whole-brain cerebral microvasculature of small organisms, such as mice, at sub-micron resolution, providing a feasible foundation for the reconstruction of circulatory pathways from the systemic to cellular scale. In this paper, we illustrate the feasibility of using this data to model cerebral(More)
Twenty patients undergoing surgery for correction of strabismus under general anesthesia were randomly selected to receive conjunctival application of 100 microliters (20 micrograms) adrenaline in both eyes or in neither (controls). A further 20 patients undergoing cataract surgery with local anesthesia were randomly selected to receive 1 ml adrenaline 1:10(More)
Light absorption and fluorescence measurements can be used to detect accumulations of small molecules in intraocular lenses (IOLs). It was shown that HEMA IOLs can store and to some extent release a variety of drugs and fluorescein. PMMA and silicone IOLs, however, do not have this characteristic. UV-blocking IOLs absorb UV light completely. The absorption(More)
