Cardiac arrest survival rates remain low despite increased access to advanced cardiac life support. Survival from cardiac arrest is, at least in part, related to the perfusion pressures and blood flow achieved during cardiopulmonary resuscitation (CPR). A number of alternative CPR devices have been developed that aim to improve the perfusion pressures and/or blood flow achieved during CPR. ⋯ A number of other devices, including the inspiratory impedance threshold valve, minimally invasive direct cardiac massage, phased chest and abdominal compression-decompression CPR, and vest CPR, are all capable of improving perfusion pressures and/or blood flow compared with standard external chest compressions. However, no convincing human outcome data has been produced yet for any of these devices. Although an interesting area of research, none of the alternative CPR devices convincingly improve long-term patient outcomes.

Immediate defibrillation is the single most effective therapy to reverse ventricular fibrillation cardiac arrest today. The once physician-only skill of defibrillation has entered mainstream society and is saving the lives of many sudden cardiac arrest (SCA) victims in a variety of settings. The automated external defibrillator (AED) and the concept of public access defibrillation (PAD) are a result of collaborative efforts between the American Heart Association (AHA) and medical manufacturers. ⋯ The success of these programs has ignited a trend in public safety and subsequently marketed the worth of AEDs in the home. Although optimal placement of AEDs remains uncertain, PAD is showing great promise in reducing the death rate from SCA. The lay public, both trained and untrained, is emerging as the next level of emergency care responders able to use a defibrillator.

ReviewTermination of resuscitation: the art of clinical decision making.
Despite all of the progress in reanimating patients in cardiac arrest over the last half century, resuscitation attempts usually fail to restore spontaneous circulation. Thus, the most common of all resuscitation decisions after initiation remains the decision to stop. ⋯ However, this most central decision is often left open to chance, provider preference, family wishes, futility judgments, and resource concerns-a host of subjective considerations at the bedside and beyond. This article sheds light on these considerations, acknowledging the pivotal role that resuscitation science and guidelines can play in the multifactorial decision to discontinue resuscitative efforts.
