Evidence of improved outcomes using patient-generated health data.

Demonstrated value depends on a collaborative approach.

Flexible nasotracheal intubation compared to blind nasotracheal intubation in the setting of simulated angioedema.

Background: Nasotracheal intubation is rarely performed in the emergency department (ED) but may be required in specific situations such as angioedema. Both blind and flexible nasal intubation (FNI) may be utilized; however, the preferred technique is unknown.

Methods: We performed a randomized, crossover manikin study using a convenience sample of emergency physicians and medical students from a local community teaching hospital.

Hot electron dominated rapid transverse ionization growth in liquid water.

Pump/probe optical-transmission measurements are used to monitor in space and time the ionization of a liquid column of water following impact of an 800-nm, 45-fs pump pulse. The pump pulse strikes the 53-μm-diameter column normal to its axis with intensities up to 2 × 10(15) W/cm2. After the initial photoinization and for probe delay times < 500 fs, the neutral water surrounding the beam is rapidly ionized in the transverse direction, presumably by hot electrons with initial velocities of 0.
