Observational Study
Disseminating Cardiopulmonary Resuscitation Training by Distributing 9,200 Personal Manikins.
Community members should be trained so that witnesses of cardiac arrests are able to trigger the emergency system and perform adequate resuscitation. In this study, the authors evaluated the results of cardiopulmonary resuscitation (CPR) training of communities in four Brazilian cities, using personal resuscitation manikins. ⋯ Instruction of CPR using personal manikins by professionals in the primary health care system seems to be a more efficient strategy for training the community than creating a training network in the schools.

Despite some focus on the use of intraosseous (IO) catheters to obtain laboratory samples, very little is known about the potential for obtaining other forms of clinical data. Largely unstudied is the relationship between IO pressures (IOPs) and systemic hemodynamic pressures such as mean arterial pressure (MAP) and central venous pressures (CVP). ⋯ The relationship between IOP and MAP or CVP is variable by site, with the MAP and CVP tending to be estimated by the femur and sternum, respectively. The relationship to actively rising pressures is nonlinear and a hysteresis model is proposed to explain the phase change. Further experimentation is needed to refine the IOP relationship to the MAP and CVP and assess the potential of these measurements to provide clinically relevant information.
