New ERC guidelines for resuscitation emphasize the need of effective and uninterrupted compressions - in line with LUCAS
In the latest ERC (European Resuscitation Council) guidelines the significance of compressions has been strongly emphasized. It states that compressions should be done with minimal interruptions as this is critical for saving the brain and to achieve and sustain coronary perfusion rates needed for survival and intact myocardial function. Moreover, more compressions should be done - the algorithm for compression/ventilation is changed to 30:2 (from 15:2). If the cardiac arrest exceeds 4 minutes - two minutes of compression should be done before defibrillation - to increase the chance of success. Finally, the compressions need to be of high-quality to have effect; "push hard and push fast" at a rate of about 100 compressions per minute without interruption, allow for chest recoil after each compression. To avoid fatigue of CPR provider it is recommended to take turns every 2 minutes.
This is in line with what LUCAS™ Chest Compression System delivers. The device assists ambulance and hospital professionals in saving cardiac arrest victims by providing continuous compressions which ensure blood flow to the brain and heart. LUCAS provides chest compressions without rescuer fatigue or variations in quality. The device enables safe transportation and allows for simultaneous defibrillation and angioplasty.
The guidelines also recognize mechanical devices as an alternative to ensure quality of chest compressions: Devices "may improve haemodynamics or short-term survival, when used by well-trained providers in selected cases. To date, no adjunct has consistently been shown to be superior to conventional manual CPR".
The following is written about LUCAS;
The Lund University Cardiac Arrest System
(LUCAS) CPR Class IIB
The Lund University Cardiac Arrest System (LUCAS) is a gas-driven sternal compression device that incorporates a suction cup for active decompressions. There are no published randomized human data comparing LUCAS CPR with manual CPR. A study of pigs with VF showed that LUCAS CPR improved hemodynamic and short therm survival compared with standard CPR. The LUCAS was also used in 20 patients, but incomplete data outcome were reported. In another pig study, in comparsion with standard CPR LUCAS-CPR increased cerebral blood flow and cardiac output. The LUCAS enables delivery of continuous compressions during transport and defibrillation. Mechanical piston CPR or LUCAS CPR may be particular useful when prolonged CPR is required; this might include during tranport to hospital or after cardiac arrest following hypothermia or poisoning."
