Randomized Controlled Trial Comparative Study Clinical Trial
ACD versus standard CPR in a prehospital setting.
Animal and human studies in cardiac arrest demonstrate significant improvements in systolic blood pressure, coronary perfusion pressure and total brain and myocardial blood flow with active compression-decompression (ACD) cardiopulmonary resuscitation (CPR). The results of recent studies in patients with out-of-hospital cardiac arrest and use of ACD-CPR are non-uniform and require supplementation. ⋯ No significant differences in hospital discharge and neurological outcome were found between STD-CPR and ACD-CPR.

Randomized Controlled Trial Clinical Trial
Rescuer's work capacity and duration of cardiopulmonary resuscitation.
Specific training in the techniques of cardiopulmonary resuscitation (CPR) has been the major aim of CPR education for both health care professionals and lay people over the past few decades. We performed a randomized trial to evaluate individual physiological parameters of 12 professional rescuers influencing duration and quality of standard CPR and active compression-decompression CPR. CPR duration was assessed according to individual work capacity after grouping rescuers as untrained and trained individuals, according to their work capacity of up to and including 100% and over 100%. ⋯ No changes in the forces of compression and decompression were measured during active compression-decompression CPR, thus demonstrating maintenance of constant CPR quality. Duration of resuscitation was influenced by the CPR method performed and by the individual work capacity (P = 0.004 and P = 0.027, respectively). We conclude that the duration of CPR depends both on the method applied and the rescuers' individual work capacity and recommend improvement of work capacity by aerobic training especially for professional rescuers.

Randomized Controlled Trial Clinical Trial
Active compression-decompression resuscitation: a prospective, randomized study in a two-tiered EMS system with physicians in the field.
Improved cardiopulmonary circulation with active compression-decompression cardiopulmonary resuscitation (ACD-CPR) has been demonstrated in studies using different animal models and a small number of humans in cardiac arrest (CA). However, prehospital studies have shown both positive and no extra benefit of ACD-CPR on return of spontaneous circulation (ROSC), hospital admission and discharge rates. The aim of our prospective study was to compare standard manual CPR (S-CPR) with ACD-CPR as the initial technique of resuscitating patients with out-of-hospital CA, with respect to survival rates and neurological outcome. ⋯ Concerning complications of CPR, there was no difference between the groups. In our two-tiered EMS system with physician-staffed ambulances, ACD-CPR neither improved nor impaired survival rates and neurological prognosis in patients with out-of-hospital cardiac arrest. The new CPR technique did not increase the complications associated with the resuscitation effort.
