Final answer:
The Head-tilt/Chin-lift technique is used to open an airway when there is no suspected trauma. It's a method that ensures an unobstructed air path by tilting the head and lifting the chin. It's critical not to use this method if a neck or spinal injury is suspected.
Step-by-step explanation:
When opening an airway with NO suspected trauma, the technique that is generally used is the Head-tilt/Chin-lift method. This technique involves tilting the patient's head back and lifting the chin upwards, which helps to straighten the airway passage and allows for better airflow to the lungs. It's important to only use this method when there's no suspicion of spinal or neck injuries as it could cause further harm in those cases.
The Head-tilt/Chin-lift maneuver is distinct from procedures such as the Heimlich maneuver, which are designed to dislodge an object from a choking person's airway. In contrast, the technique like endotracheal intubation may be utilized during surgeries under general anesthesia to maintain an open airway and is performed by medical professionals.
