Cricoid pressure refers to a small amount of manual pressure applied to the cricoid cartilage of the trachea during CPR. It is a technique used by rescuers which tries to maintain a patent airway during cardiopulmonary resuscitation. During CPR sometimes the trachea is not open sufficiently to ventilate the patient. Resistance may be felt by the person using the ambu bag or pressure is felt by the person giving breathes via a face shield/mask. Repositioning of the airway is important to maintain an effective delivery of oxygen to the victim. A head tilt, chin lift method can also be employed to reposition the airway ( if no cervical or head trauma exists). If trauma is present, a jaw thrust maneuver can be used in place of the head tilt, chin lift.
