Before initiating cooling, confirm eligibility and gather materials.

  • Obtain 2 cooling blankets and cables (one machine) to “sandwich” the patient; each blanket should have a sheet covering it to protect the patient’s skin

  • Alternatively, place heat-exchange pads on the patient per the manufacturer’s recommendation

  • Pack the patient in ice (groin, chest, axillae, and sides of neck); use additional measures as needed to bring the patient to a temperature between 32°C and 36°C; avoid packing ice on top of the chest, which may impair chest wall motion

  • Monitor vital signs and oxygen saturation and place the patient on a continuous cardiac monitor, with particular attention to arrhythmia detection and hypotension

  • Once a temperature below the goal temperature is reached, remove ice bags and use the cooling blanket or heat-exchange device to maintain temperature between 32°C and 36°C [2]
