Methods and devices to improve the efficacy of mechanical cardiopulminary resuscitation by changing the position of chest compression

Abstract

A system and method for mechanical CPR can include a device for providing compressive force to various locations on a patient, and biological monitoring systems to measure the effectiveness of the various locations of compressive force in pumping blood through the patient. The system can also include providing decompressive force to increase the efficacy of blood flow.

What is claimed is: 
     
         1 . A system for providing personalized CPR comprising:
 one or more pistons operatively connected to suction cups adapted to provide a decompressive force at a plurality of locations on a patient;   one or more biological monitoring systems adapted to measure feedback from one or more biological systems as the decompressive force is applied at the plurality of locations on the patient; and   a processor adapted to compare the feedback as the decompressive force is applied at a first location of the plurality of locations on the patient and at a second location of the plurality of locations on the patient.   
     
     
         2 . A method for providing personalized CPR comprising:
 applying a compressive force to a patient at a first location and releasing the compressive force at the first location in a first compression cycle;   measuring biological feedback of the patient from a biological sensor during the first compression cycle at the first location;   applying a compressive force to the patient at a second location and releasing the compressive force at the second location in a second compression cycle;   measuring biological feedback of the patient from the biological sensor during the second compression cycle at the second location; and   comparing the biological feedback of the patient measured during the first compression cycle to the biological feedback of the patient measured during the second compression cycle to determine a best location for a best compression cycle that provides the best blood flow for the patient.   
     
     
         3 . The method of  claim 2 , further comprising:
 applying a compressive force to the patient at a new location and releasing the compressive force at the new location in a new compression cycle;   measuring biological feedback of the patient from the biological sensor during the new compression cycle at the new location; and   comparing the biological feedback of the patient measured during the new compression cycle to the biological feedback of the patient measured during the best compression cycle to determine a new best location for a new best compression cycle.   
     
     
         4 . The method of  claim 2 , further comprising:
 applying a decompressive force to a patient at a first decompression location and releasing the decompressive force at the first decompression location in a first decompression cycle;   measuring biological feedback of the patient from the biological sensor during the first decompression cycle;   applying a decompressive force to the patient at a second location and releasing the decompressive force at the second location in a second decompression cycle;   measuring biological feedback of the patient from the biological sensor during the second decompression cycle; and   comparing the biological feedback of the patient measured during the first decompression cycle to the biological feedback of the patient measured during the second decompression cycle to determine a best location for a best decompression cycle that provides the best blood flow for the patient.   
     
     
         5 . The method of  claim 4 , wherein applying a decompressive force further comprises providing active suction.
