Study objective: In a previous cardiopulmonary resuscitation (CPR) study in swine, ventilation was associated with improved rate of return of spontaneous circulation (ROSC) compared with nonventilated animals, which had greater hypoxia and hypercarbic acidosis. We used the same model to determine the independent effect of hypoxia and hypercarbic acidosis on ROSC after cardiac arrest. Design: Laboratory...
Study Objective: To compare the concentration of a rescuer's exhaled O 2 and CO 2 during mouth-to-mouth ventilation with or without chest compression. Design: Prospective repeated measures study. Simulated one- and two-rescuer cardiopulmonary resuscitation (CPR) was performed as recommended by the American Heart Association. Setting: University laboratory. Participants: Fifty-five...
