Henry Bessemer was an inventor and engineer from England. Not only  did he develop the Bessemer process for steel manufacturing, but he  also designed a machine that could mâ¦ake bronze powder.
The head-tilt/chin-lift is the primary maneuver used in any patient in whom cervical spine injury is not a concern. The simplest way of ensuring an open airway in an unconscious patient is to use a head-tilt/chin-lift technique, thereby lifting the tongue from the back of the throat.
Once the airway is unblocked, place your hand on victim's forehead and your other hand under the tip of the chin and gently tilt his head backward [show me]. In this position the weight of the tongue will force it to shift away from the back of the throat, opening the airway.
