          Cardiopulmonary resuscitation ( CPR) training in schools can increase the rate of bystander CPR. We assessed whether a “Quality CPR ( QCPR) Classroom” can support CPR performance by students trained by a teacher who is not a CPR instructor.


          A cluster randomized trial was undertaken to assess the effectiveness of a 50‐min Practice While Watch CPR training program enhanced by QCPR Classroom, which used 42 manikins connected by Bluetooth to real‐time feedback monitoring. Fifty‐seven students were divided into Group 1, taught by a non‐ CPR‐instructor, and Group 2, taught by a CPR instructor. Psychomotor and cognitive tests were administered before and after training. Primary outcomes were post‐training compression depth and rate and percent of improvement in adequate depth, recoil, and overall score. The secondary outcome was risk improvement.


          Post‐training, Group 1 achieved 62.1 ± 7.7 mm and 118.0 ± 3.6 compressions/min whereas Group 2 achieved 57.4 ± 9.8 mm and 119.8 ± 5.4 compressions/min. The overall score improvement in percentage points was 36.4 ± 25.9% and 27.0 ± 27.7%, respectively ( P ≤ 0.001 for both). The adequate depth improvement in percentage points was 22.4 ± 35.4% and 32.5 ± 40.0%, respectively ( =  0.33). Teaching by a non‐ CPR instructor improved student cognitive knowledge.


          Using a QCPR Classroom to enhance CPR teaching by a non‐ CPR‐instructor results in similar or better outcomes compared to using a CPR instructor. Use of a Practice While Watch QCPR Classroom will provide adequate quality in preparing students for CPR.


          In this study, we assessed whether a “Quality CPR (QCPR) Classroom”, a cardiopulmonary resuscitation (CPR) feedback device for use in classrooms, can support CPR performance among students trained by a teacher who is not a CPR instructor. We compared CPR skills and cognitive knowledge between the group led by an experienced teacher who was not a CPR instructor and the group led by an experienced CPR teacher. The groups did not differ in improvement.

          Early cardiopulmonary resuscitation in out-of-hospital cardiac arrest.

          Three million people in Sweden are trained in cardiopulmonary resuscitation (CPR). Whether this training increases the frequency of bystander CPR or the survival rate among persons who have out-of-hospital cardiac arrests has been questioned.

            Out-of-hospital cardiac arrest is associated with low survival, but early cardiopulmonary resuscitation (CPR) and defibrillation can improve outcomes if more widely adopted.

              Effectiveness of bystander-initiated cardiac-only resuscitation for patients with out-of-hospital cardiac arrest.

              Previous animal and clinical studies suggest that bystander-initiated cardiac-only resuscitation may be superior to conventional cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrests. Our hypothesis was that both cardiac-only bystander resuscitation and conventional bystander CPR would improve outcomes from out-of-hospital cardiac arrests of 15 minutes. We carried out a prospective, population-based, observational study involving consecutive patients with emergency responder resuscitation attempts from May 1, 1998, through April 30, 2003. The primary outcome measure was 1-year survival with favorable neurological outcome. Multivariable logistic regression analysis was performed to evaluate the relationship between type of CPR and outcomes. Among the 4902 witnessed cardiac arrests, 783 received conventional CPR, and 544 received cardiac-only resuscitation. Excluding very-long-duration cardiac arrests (> 15 minutes), the cardiac-only resuscitation yielded a higher rate of 1-year survival with favorable neurological outcome than no bystander CPR (4.3% versus 2.5%; odds ratio, 1.72; 95% CI, 1.01 to 2.95), and conventional CPR showed similar effectiveness (4.1%; odds ratio, 1.57; 95% CI, 0.95 to 2.60). For the very-long-duration arrests, neurologically favorable 1-year survival was greater in the conventional CPR group, but there were few survivors regardless of the type of bystander CPR (0.3% [2 of 624], 0% [0 of 92], and 2.2% [3 of 139] in the no bystander CPR, cardiac-only CPR, and conventional CPR groups, respectively; P<0.05). Bystander-initiated cardiac-only resuscitation and conventional CPR are similarly effective for most adult out-of-hospital cardiac arrests. For very prolonged cardiac arrests, the addition of rescue breathing may be of some help.
