Device and System for Enhancing Cardiopulmonary Resuscitation

The invention pertains to devices and systems for externally compressing or collapsing peripheral vasculature during Cardiopulmonary Resuscitation (CPR) to redirect blood to the torso and head regions, thereby enhancing the likelihood of CPR success. The system includes a plurality of sleeves adapted for placement on a patient's limbs during CPR, each sleeve including at least one inflatable fluid chamber and at least one inflation source fluidly coupled to each of the inflatable fluid chambers of the sleeves. The sleeve chambers can be inflated to a desired compression pressure and maintained at the desired compression pressure continuously throughout CPR to prevent or restrict blood flow in the limbs. The desired compression pressure can be sufficient to redirect substantial blood volume from the patient's limbs to the patient's torso and head regions during CPR.

Potential Commercial Applications: Competitive Advantages:
  • Cardiopulmonary resuscitation
  • Peripheral blood occlusion
Improves CPR outcomes –
  • Can be used with or independent of automated CPR devices and pharamacotherapies.
  • Can be utilized in a public setting by a lay person.
  • Extent and duration of vascular occlusion can be specifically prescribed.
  • May be used to alter preload.
  • May increase pulse wave velocity and/or wave reflection magnitude resulting in increased pulse and/or perfusion pressures.

  • Development Stage:
    • Early-stage
    • Prototype
