Case Reports
An incidental image of a patient with chest pain after fall from a tree: Swyer-James-MacLeod syndrome?
Unilateral hyperlucent lung was firstly described by Swyer and James 1950s. After that, some patients with same disease were detected by Macleod. Then this syndrome was named as Swyer- James-Macleod syndrome (SJMS), and this syndrome includes a smaller or normal sized unilateral hyperlucent lung. ⋯ In his computed tomography no rib fracture, pneumothorax and hemothorax. But an abnormal image (5.5 cm hyperlucent area) was seen in his left lung. This report aims to present one of incidentally diagnosed rare case of SJMS.

The role of circulatory support in the post-cardiac arrest period remains controversial. Our objective was to investigate the association between treatment with a percutaneous hemodynamic support device and outcome after admission for cardiac arrest. ⋯ Treatment with percutaneous hemodynamic support device in the post-arrest period may provide left ventricular support and improve outcome.

Observational Study
Are three ports better than one? An evaluation of flow rates using all ports of a triple lumen central venous catheter in volume resuscitation.
Poiseuille's law states flow rates are directly proportional to the radius to the 4th power and indirectly proportional to the length of a tube. Because of this property, large bore catheters are commonly used in the resuscitation of the critically ill patient. However, there are no studies comparing simultaneous use of all three lumens of a triple lumen (TL) central venous catheter (CVC) with other catheter types. Our objective was to compare the flow rates of normal saline (NS) through various resuscitation catheters against a TL CVC using all 3 ports. ⋯ Simultaneous use of all 3 ports of a TL CVC generates flow rates comparable to many other commonly used resuscitation catheters.

Randomized Controlled Trial Comparative Study
Resuscitation quality of rotating chest compression providers at one-minute vs. two-minute intervals: A mannequin study.
The aim of this randomized cross-over study was to compare one-minute and two-minute continuous chest compressions in terms of chest compression only CPR quality metrics on a mannequin model in the ED. ⋯ There was no statistically significant difference in the quality metrics of chest compressions between 1- and 2-minute chest compression only groups.

Automated external defibrillators (AEDs) emerged in the 1980s as an important innovation in pre-hospital emergency cardiac care (ECC). In the years since, the American Heart Association (AHA) and the International Liaison Committee for Resuscitation (ILCOR) have promoted AED technology for use in hospitals as well, resulting in the widespread purchase and use of AED-capable defibrillators. ⋯ This article will discuss the issue of AEDs in the hospital using a conceptual framework provided by recent work on medical reversal. It will go on to consider the implications of the reversal for in-hospital resuscitation programs and emergency medicine more generally.
