To survey the recent medical literature examining studies of the hemodynamic effects of mechanical ventilation. ⋯ PPV and SVV predict volume responsiveness, but like all monitoring approaches, need to be understood within the framework of their physiologic determinations.

The 2010 Cardiopulmonary Resuscitation (CPR) Guidelines recommended therapeutic hypothermia for postcardiac arrest syndrome as a beneficial and effective treatment. However, the optimal temperature, method, onset, duration and rewarming rate, and therapeutic window remain unknown. ⋯ One of the most significant advances in CPR treatment in the past decade is therapeutic hypothermia. Although post-ROSC cooling has been shown to improve neurological outcome for patients with out-of-hospital cardiac arrest, intra-arrest cooling during CPR is likely to protect the myocardium from reperfusion injury and enhance neurological benefits.

The role of cardiac arrest centers, more recently termed Cardiac Receiving Centers, in improving outcomes after successful resuscitation is becoming more and more convincing. But which of all the treatments provided by Cardiac Receiving Centers are most beneficial is less certain. This review examines the role of early coronary angiography and percutaneous coronary intervention in this regard. ⋯ Emergent coronary angiography and percutaneous coronary intervention are the most important Cardiac Receiving Center treatments beyond hypothermia. Providing both of these essential postresuscitation therapies is the very purpose of such centers.

ReviewDispatch-assisted cardiopulmonary resuscitation: the anchor link in the chain of survival.
Early bystander cardiopulmonary resuscitation (CPR) provides a vital bridge after collapse from cardiac arrest until defibrillation can be performed. However, due to multiple barriers and despite large-scale public CPR training, this life-saving therapy is still not rendered in a majority of cardiac arrest events. As a result, cardiac arrest survival remains very low in most communities. ⋯ This review focuses on the rationale and evolving science behind dispatch CPR instructions, as well as some best practices for implementing and measuring dispatch-assisted CPR with the goal of maximizing its potential to save lives from sudden cardiac arrest.
