Software failure of glidescope video laryngoscope during intubation attempt on cardiac arrest patient.Large error box displayed in center of screen interfering with view of vocal cords making it impossible to intubate patient successfully.Attempts made to reboot glidescope, but failed as unit would not shut off or reboot.Attempts to intubate with error on screen while staff looked for alternative intubation laryngoscope failed despite trying to position view of vocal cords above and to the left of the error message on the screen.This resulted in highly suboptimal positioning of scope above vocal cords and made intubation impossible.Unable to intubate and secure/protect airway.Resorted to bagging only as no other laryngoscope readily available.Patient expired from her cardiac arrest.Fda safety report id# (b)(4).
