Unlabelled: High-quality chest compressions are pivotal to improve survival from cardiac arrest. Basic life support training of school students is an international priority. The aim of this trial was to assess the effectiveness of a real-time training software (Laerdal QCPR®) compared to a standard instructor-based feedback for chest compressions acquisition in secondary school students. After an interactive frontal lesson about basic life support and high quality chest compressions, 144 students were randomized to two types of chest compressions training: 1) using Laerdal QCPR® (QCPR group- 72 students) for real-time feedback during chest compressions with the guide of an instructor who considered software data for students' correction 2) based on standard instructor-based feedback (SF group- 72 students). Both groups had a minimum of a 2-minute chest compressions training session. Students were required to reach a minimum technical skill level before the evaluation. We evaluated all students at 7 days from the training with a 2-minute chest compressions session. The primary outcome was the compression score, which is an overall measure of chest compressions quality calculated by the software expressed as percentage. 125 students were present at the evaluation session (60 from QCPR group and 65 from SF group). Students in QCPR group had a significantly higher compression score (median 90%, IQR 81.9-96.0) compared to SF group (median 67%, IQR 27.7-87.5), p = 0.0003. Students in QCPR group performed significantly higher percentage of fully released chest compressions (71% [IQR 24.5-99.0] vs 24% [IQR 2.5-88.2]; p = 0.005) and better chest compression rate (117.5/min [IQR 106-123.5] vs 125/min [115-135.2]; p = 0.001). In secondary school students, a training for chest compressions based on a real-time feedback software (Laerdal QCPR®) guided by an instructor is superior to instructor-based feedback training in terms of chest compression technical skill acquisition.

Article Synopsis
- Spondylo-thoracic dysplasia (STD) is a rare congenital condition that affects the vertebrae and thoracic area, often leading to serious respiratory issues and a high risk of early death in neonates.
- The text details the case of a one-day-old male newborn with severe respiratory distress and various physical anomalies, including scoliosis and rib deformities, identified through clinical examinations and imaging studies.
- The baby was diagnosed with STD, received conservative management, and survived past the neonatal period, offering insights into this particular variant of the condition.

Combustion of surgical drapes during surgery is a rare event which can nonetheless lead to serious consequences. Iatrogenic burns caused by this complication are often deep and lead to functional and aesthetic sequelae. Nevertheless, awareness of the triggering factors and mechanisms, as well as knowledge of the proper use of various at-risk products such as alcohol-based antiseptic agents and compressed oxygen can reduce the incidence of these undesirable events.

Introduction: There is a risk of iatrogenic vascular injuries during robotic-assisted laparoscopic excision of diaphragmatic endometriosis. Although studies are limited, the first reported case of a suprahepatic inferior vena cava (IVC) injury during robotic diaphragmatic endometriosis excision was successfully treated using a fibrin sealant patch, preventing exsanguination and conversion to laparotomy.
Case Description: A 36-year-old female with a history of recurrent catamenial pneumothorax and two prior video-assisted thoracoscopic surgeries to treat diaphragmatic endometriosis presented to our clinic with right-sided shoulder pain and a chest tube in place.

Christine A. Schindler is a critical care pediatric nurse practitioner, critical care advanced practice provider program director, Children's Wisconsin/Medical College of Wisconsin, and a clinical professor, Marquette University, Milwaukee, Wisconsin.
Background: The quality cardiopulmonary resuscitation (CPR) coach role was developed for hospital-based resuscitation teams. This supplementary team member (CPR coach) provides real-time, verbal feedback on chest compression quality to compressors during a cardiac arrest.
Objectives: To evaluate the impact of a quality CPR coach training intervention on resuscitation teams, including presence of coaches on teams and physiologic metrics of quality CPR delivery in real compression events.

Background: A mnemonic is a cognitive aid frequently used in health-related education. The main goal of this study was to develop and test a 5-finger mnemonic for teaching schoolchildren the theoretical aspects of adult Basic Life Support (BLS) steps, a process rarely described in the context of instructing laypersons.
Methods: Experts from the European Resuscitation Council's Basic Life Support Science and Education Committee (ERC BLS SEC), specializing in teaching adult BLS, participated in the first phase of the pilot study.
