Direct laryngoscopy dates to 1849. Progress continued into the late 40s and beyond. Success in prehospital care varied. In the 1980s, video laryngoscopy arose and allowed greater visualization of the glottic opening and eventually recording. See it, record it. Additional airway adjuncts became available, such as supraglottic airways. All of these are dependent, to a variable degree, on the user’s skills and any time constraints.
