Randomized Controlled Trial
Cardiopulmonary resuscitation using the lifeline ARM mechanical chest compression device: a randomized, crossover, manikin trial.
European Resuscitation Council as well as American Heart Association guidelines for cardiopulmonary resuscitation (CPR) stress the importance of uninterrupted and effective chest compressions (CCs). Manual CPR decreases in quality of CCs over time because of fatigue which impacts outcome. We report the first study with the Lifeline ARM automated CC device for providing uninterrupted CCs. ⋯ Mechanical CCs in our study adhere more closely to current guidelines than manual CCs. The Lifeline ARM provides more effective CCs, more ventilation time and minute volume, less hands-off time, and less decrease in effective CCs over time compared with manual Basic Life Support and might therefore impact outcome.

To determine the impact of delayed admission to the intensive care unit (ICU) on the clinical outcomes of patients with acute respiratory failure (ARF) in the emergency department (ED). ⋯ For patients with ARF who required mechanical ventilation support and intensive care, a delayed ICU admission more than 1.0 hour is a strong determinant of mortality and is associated with a longer ICU stay and a longer need for ventilation.

Randomized Controlled Trial
Does gender bias in cardiac stress testing still exist? A videographic analysis nested in a randomized controlled trial.
Despite a high prevalence of coronary heart disease in both genders, studies show a gender disparity in evaluation whereby women are less likely than men to undergo timely or comprehensive cardiac investigation. Using videographic analysis, we sought to quantify gender differences in provider recommendations and patient evaluations. ⋯ Despite a lower pretest probability of acute coronary syndrome in women, we did not observe any significant gender disparity in how patients were managed and evaluated. When the patients' and providers' gender matched, the provider involved them less in the decision making process, and the information provided was less helpful than when the genders did not match.

Assessment of right ventricular (RV) function in acute pulmonary embolism (PE) has prognostic significance. The aim of this study was to evaluate right atrium (RA) and RV myocardial damage with 2-dimensional speckle-tracking in patients with an acute central vs an acute peripheral PE. ⋯ This pilot study suggests that basal-/mid-segments of RA and RV free wall are more affected in patients with a PE compared with controls. Interestingly, we found no significant difference in myocardial RA and RV damage between patients with a central and a peripheral PE. We advocate that PE no matter central or peripheral is a serious condition and that a peripheral PE has to be intensively treated similar to a central PE.

The HEART Pathway is a diagnostic protocol designed to identify low-risk patients presenting to the emergency department with chest pain that are safe for early discharge. This protocol has been shown to significantly decrease health care resource utilization compared with usual care. However, the impact of the HEART Pathway on the cost of care has yet to be reported. ⋯ Using the HEART Pathway as a decision aid for patients with undifferentiated chest pain resulted in significant cost savings.
