Patient monitoring is more than just the acquisition and accumulation of physiological data. In order for it to be efficacious in patient diagnosis and treatment, the professional staff must be continuously involved in protocol development, evaluation, and modification. Given the constraints of these tasks, of cost limitations, and of staff interest and(More)
OBJECTIVE The Association of Program Directors in Surgery and the Division of Education of the American College of Surgeons developed and implemented a web-based system for end-of-rotation faculty assessment of ACGME core competencies of residents. This study assesses its reliability and validity across multiple programs. METHODS Each assessment included(More)
The submental-vertical (S-V) radiograph has become popular in the assessment of craniofacial asymmetry because of ease in identifying reliable midline reference structures. To date, no standards of asymmetry that use the S-V projection have been reported. Submental-vertical radiographs were obtained on 44 adults. Subjects were excluded if previous(More)
The purpose of this study was to measure the relationship between quantitative changes in an epicardial electrocardiographic complex and times of total occlusion and reactive hyperemia in the coronary vessel that supplied the myocardium beneath the electrode. Fifty-six experiments were performed on 9 open-chest dog preparations in which the left anterior(More)
• In the usual procedure for determination of indicator dilution curves, the sensing or measuring device is placed at some distance from the sampling site. The fluid is transported by a sampling system, usually a catheter, from the withdrawal site to the sensing point. This sampling system always introduces some distortion in the time-concentration curve,(More)
A combined pulsed and continuous Doppler instrument was used to assess flow velocities in an in vitro model designed to simulate small deeply lying arterial vessels. Diameters of the model vessels, depth under the transducers and the pulsatile flow patterns were chosen to simulate the corresponding conditions that can be expected when cerebral blood flow(More)
