BACKGROUND: Because mobile telephones may support video calls, emergency medical dispatchers may now connect visually with bystanders during pre-hospital cardio-pulmonary resuscitation (CPR). We studied the quality of simulated dispatcher-assisted CPR when guidance was delivered to rescuers by video calls or audio calls from mobile phones. METHODS: One hundred and eighty high school students were randomly assigned in groups of three to communicate via video calls or audio calls with experienced nurse dispatchers at a Hospital Emergency Medical Dispatch Center...

The purpose of this study was to examine the potential interaction of core temperature and isocapnic hypoxia on human ventilation and heart rate (HR). In 2 resting head-out water-immersion trials, 8 males first breathed air and then 12% O2 in N2 while the end-tidal partial pressure of carbon dioxide was kept 0.98 (0.66) mmHg (mean (SD)) above normothermic resting levels. The first immersion trial was with a normothermic esophageal temperature (Tes) of approximately 36.7 degrees C, and for the second trial, 1 h later, water temperature was increased to give a hyperthermic Tes of approximately 38...

UNLABELLED: The aim of the study was to evaluate spiroveloergometric and blood gases data and compare them among swimmers and basketball players. Examinations were performed for swimmers and basketball players (n=85). Spirometry at rest and spiroveloergometry, analysis of blood gases and acid-base equilibrium at rest and during exercise were performed. Minute ventiliation of swimmers at rest was statistically significantly (p<0.001) lower than of basketball players: 11.0 l/min and 22...

Propagating illofemoral venous thrombosis that occurs despite adequate anticoagulation can be detected by the serial fibrinogen uptake test. Twenty-three patients who were receiving heparin sodium for confirmed iliofemoral thrombophlebitis underwent the serial fibrinogen uptake test. There was an increasing percentage of isotope uptake at the groin and the upper part of the thigh in eight of these patients, three of whom subsequently developed clinical signs, perfusion, and ventiliation lung scan findings compatible with the occurrence of pulmonary embolism...
