Randomized Controlled Trial Comparative Study
Comparison of Bag-Valve-Mask Hand-Sealing Techniques in a Simulated Model.
Bag-valve-mask ventilation remains an essential component of airway management. Rescuers continue to use both traditional 1- or 2-handed mask-face sealing techniques, as well as a newer modified 2-handed technique. We compare the efficacy of 1-handed, 2-handed, and modified 2-handed bag-valve-mask technique. ⋯ In a simulated model, both 2-handed mask-face sealing techniques resulted in higher ventilatory tidal volumes than 1-handed technique. Tidal volumes from 2-handed and modified 2-handed techniques did not differ. Rescuers should perform bag-valve-mask ventilation with 2-handed techniques.

Randomized Controlled Trial Comparative Study
A Comparison of Two Open Surgical Cricothyroidotomy Techniques by Military Medics Using a Cadaver Model.
The CricKey is a novel surgical cricothyroidotomy device combining the functions of a tracheal hook, stylet, dilator, and bougie incorporated with a Melker airway cannula. This study compares surgical cricothyroidotomy with standard open surgical versus CricKey technique. ⋯ Compared with the standard open surgical cricothyroidotomy technique, military medics demonstrated faster insertion with the CricKey. First-pass success was not significantly different between the techniques.
