The Future of CPR

I got to interview two cutting edge researchers on what CPR will look like in the next decade; their answers were fascinating.

Flow-Enhanced CPR

They discuss the use of the impedance threshold device and the active-compression/decompression device to augment flow during CPR. See the results of the ResQ trial listed below to see what this does in cardiac arrest patients.

Note: Dr. Lurie is the founder, chief medical officer, and a major shareholder of the company that manufactures these two devices. Dr. Yannopoulos has no conflicts of interest.



Reperfusion Injury Protection

Stutter CPR is giving 3 cycles of 20 seconds of compressions/ventilations, 20 seconds of pause. In pigs, this has markedly reduced the reperfusion injury when resuscitating a patient with prolonged arrest.

New Medications

Sodium nitroprusside (in addition to small doses of epi and flow-enhanced CPR) increases flow to the heart and the brain. May also blunt reperfusion injury to heart and brain. In addition adenosine and cyclosporine A may have a role as well.

Note: None of this is ready for clinical use–this may be the future, it is not the present
