The head tilt-chin lift technique is recommended for opening the airway in an unconscious adult during CPR because it effectively elevates the tongue away from the back of the throat, thus allowing for better air passage. This technique involves tilting the head back slightly and lifting the chin up, which helps to prevent airway obstruction by maximizing the space in the pharynx.

This approach is critical in the context of CPR as it is necessary to ensure that the airway is clear before providing rescue breaths. An open airway is vital for delivering oxygen to the lungs and ensuring that circulation can effectively support the body's needs during a cardiac arrest scenario.

The jaw-thrust maneuver is also a valid method for opening the airway, particularly when there is concern for a cervical spine injury. However, it is generally used when the head tilt-chin lift might compromise the patient’s safety. In cases where spinal injury is not suspected, the head tilt-chin lift is typically the preferred technique because it is quicker and easier to perform.

Options such as placing the patient in a semi-Fowler's position or using a suction device are not standard practices for opening the airway during CPR. The semi-Fowler's position is not suitable for unconscious patients who are incapable of maintaining their airway or breathing spontaneously
