Noninvasive Prehospital Cooling Using the Cryo Cooling System

  • Average temperature drop of 1.7°C in 31 minutes1
    –  
    Tympanic temperature in healthy volunteers (University Hospitals, Cleveland, OH).
  • Average temperature drop of 1.3°C in 45 minutes2
        Esophageal temperature in cardiac transport patients already cooled via chilled saline.  (VitaLink/AirLink Critical Care Transport, New Hanover, NC)
  • Equal temperature drop to Chilled Saline – 1.5°C for Cryothermic vs. 1.4°C for Chilled Saline3
    Tympanic temperature drop in prehospital SCA patients (Prague, CZ)


Evidence Supports Early Cooling as an Alternative to Saline for SCA

AMERICAN HEART ASSOCIATION GUIDELINES 2015

The Task Force recommends targeted temperature management for adults with out-of-hospital cardiac arrest with an initial shockable rhythm at a constant temperature between 32°C and 36°C for at least 24 hours.

Similar suggestions are made for out-of-hospital cardiac arrest with a nonshockable rhythm and in-hospital cardiac arrest. The Task Force recommends against prehospital cooling with rapid infusion of large volumes of cold intravenous fluid.2

Issues with Chilled Saline

issues with chilled saline and cooling of body

AHA & ILCOR STRONGLY RECOMMEND AGAINST COOLING WITH SALINE:3

  • Hard to maintain cooling consistancy –  patients re-warm.
  • High rate of re-arrest (26%) and pulmonary edema.4
  • Shivering is common side effect.

Not All Cooling Packs Are Created Equal

THE CRYOTHERMIC COOLING PACK IS 15°C COLDER THAN STANDARD ICE PACKS

  • Reaches -5.0°C in seconds
  • Skin safe (proprietary fabric)
  • 20-30 minutes below 0°C

Economic Impact of Fever

economic impact of fever in hospital patients

ICU &HOSITAL ECONOMIC IMPACT OF FEVER

Fever is detrimental in the setting of acute neurologic insults, and approximately 70% of Neurologic Intensive Care patients develop fever.

The increased length of stay due to fever equates to an estimate of $10,074 in additional ICU costs and $17,414 in additional hospital costs.5
