Resuscitation
-
This observational study aims to describe: (1) the use of positive pressure ventilation (PPV) for resuscitation in the delivery room among newly born near-term infants; (2) the methods used for PPV resuscitation [e.g., bag-facial mask (BFM), laryngeal mask airway (LMA), endotracheal tube (ETT)]; and (3) the association of each device with short-term neonatal outcomes. ⋯ The LMA is an effective device for primary airway management of near-term infants and for secondary airway management among near-term infants failing BFM or ETT resuscitation.

Randomized Controlled Trial
Performance of chest compressions by laypersons during the Public Access Defibrillation Trial.
Increasing evidence indicates that health professionals often may not achieve guideline standards for cardiopulmonary resuscitation (CPR). Little is known about layperson CPR performance. ⋯ In this study of trained laypersons, CPR varied substantially and often did not achieve guideline parameters. The findings suggest a need to improve CPR training, consider changes to CPR protocols, and/or improve the AED-rescuer interface.

Comparative Study
Capnography and chest-wall impedance algorithms for ventilation detection during cardiopulmonary resuscitation.
Hyperventilation is both common and detrimental during cardiopulmonary resuscitation (CPR). Chest-wall impedance algorithms have been developed to detect ventilations during CPR. However, impedance signals are challenged by noise artifact from multiple sources, including chest compressions. Capnography has been proposed as an alternate method to measure ventilations. We sought to assess and compare the adequacy of these two approaches. ⋯ Both the impedance and capnography-based algorithms underestimated the ventilation rate. Reliable ventilation rate determination may require a novel combination of multiple algorithms during resuscitation.
