1. An airway adjunct resuscitation system for use during administration of a resuscitative procedure to a patient, the system comprising:
- a support assembly defining an intrathoracic pressure monitoring lumen, a cooling fluid delivery lumen, a cooling fluid return lumen, and an orogastric lumen, wherein the orogastric lumen is adapted for use in removing gastric contents from the patient during administration of the resuscitative procedure to the patient;
a laryngeal cuff assembly coupled with the support assembly, wherein the laryngeal cuff assembly is positioned within the patient'"'"'s supraglottic airway at least in part by the support assembly, wherein the laryngeal cuff assembly at least partially isolates and seals a portion of the supraglottic airway of the patient, and wherein the laryngeal cuff assembly operates to assist in positioning a distal section of the intrathoracic pressure monitoring lumen in fluid communication with the patient'"'"'s trachea, during administration of the resuscitative procedure to the patient;
an esophageal cuff assembly coupled with the support assembly distal to the laryngeal cuff assembly, wherein the esophageal cuff assembly interfaces with the esophagus of the patient during administration of the resuscitative procedure to the patient; and
a fluid passage circuit defined at least in part by the esophageal cuff assembly and in fluid communication with the fluid delivery lumen and the fluid return lumen of the support assembly.
