Intense exertion is an occupational hazard inherent to fire fighting. This study was designed to look at the exertion levels that fire fighters attain during a fire fighting exercise when using (1) no self-contained breathing apparatus (SCBA), (2) light SCBA, and (3) heavy SCBA. Exertion levels were measured as a function of the heart rate increase relative(More)
OBJECTIVE Pulse contour cardiac output (PCCO) analysis is a technique for continuous cardiac output (CO) monitoring through an arterial catheter after calibration by transpulmonary thermodilution (TPTD). Studies in adults show good correlation with pulmonary artery thermodilution (PATD) CO. Data are limited in children and patients with hemodynamic(More)
BACKGROUND Blunt abdominal trauma that leads to hemorrhagic shock and cardiac arrest is almost always fatal in the prehospital setting. The current study investigated whether a hemoglobin-based oxygen carrier (HBOC-201) could maintain organ viability during an exsanguinating liver injury and allow for prolonged survival. This hypothesis was tested in a(More)
STUDY OBJECTIVES To demonstrate the technique of selective aortic arch perfusion during cardiac arrest and to observe the hemodynamic effects of volume infusion and aortic epinephrine administration. DESIGN Sequential series, nonrandomized, noncontrolled. TYPE OF PARTICIPANTS Fourteen mongrel dogs weighing 21 to 36 kg. INTERVENTIONS Animals had(More)
In the setting of rapidly exsanguinating hemorrhage, resuscitation with intravenous (i.v.) crystalloid solution may not sustain survival before availability of allogenic blood transfusion and surgery. This study tested the hypothesis that bovine hemoglobin-based oxygen carrier, HBOC-201, would improve resuscitation and extend early survival from(More)
We are investigating the potential of 3D telepresence, or televideo, technology to support collaboration among geographically separated medical personnel in trauma emergency care situations. 3D telepresence technology has the potential to provide richer visual information than current 2D video conferencing techniques. This may be of benefit in diagnosing(More)
We conducted an experiment with a posttest, between-.subjects design to evaluate the potential of emerging 3D telepresence technology to support collaboration in emergency healthcare. 3D telepresence technology has the potential to provide richer visual information than current 2D video conferencing techniques. This may be of benefit in diagnosing and(More)
Two-dimensional (2D) videoconferencing has been explored widely in the past 15-20 years to support collaboration in healthcare. Two issues that arise in most evaluations of 2D videoconferencing in telemedicine are the difficulty obtaining optimal camera views and poor depth perception. To address these problems, we are exploring the use of a small array of(More)
Introduction. This paper focuses on paramedics' perspectives regarding paramedic-physician collaboration today, and their perspectives regarding the potential of 3D telepresence technology in the future. Method. Interviews were conducted with forty practicing paramedics. Analysis. The interview data were analysed using open and axial coding. An agreement of(More)
