With the LUCAS device, fatigue, individual variations or psychological factors are removed from CPR and there is no longer a need for switching CPR providers every two minutes. LUCAS helps provide high-quality and safer chest compressions in situations such as patient movement and transportation, during prolonged CPR or in the cath lab.

Caregivers cannot deliver optimal care if they are at risk of injury on the job. From the field to the cath lab,the LUCAS device reduces risks to caregivers while maintaining Guidelines-consistent chest compressions.
The ambulance transport environment is inherently dangerous because of high-speed driving, risky maneuvers and hazardous road conditions. This poses a significant safety risk for the EMS crew who are often standing and unrestrained in a confined space while performing CPR.

Sometimes advanced life-support like CPR and defibrillation alone are not enough to achieve a stable pulse in the patient. In a wide range of case reports of refractory VF or PEA, LUCAS has been the critical tool for making transportation to the cath lab possible, followed by emergency angiography with life-saving PCI intervention during ongoing LUCAS circulatory support.
This angiography shows a heart in cardiac arrest. After a short while LUCAS is started and the contrastmedia is immediately circulated.
The LUCAS device sustains the blood circulation of cardiac arrest patients in the cath lab and allows for simultaneous intervention to treat the cause of the arrest.
The LUCAS device is mostly radiotranslucent except for the hood and compression mechanism.
Most radiological projection angles can be used during LUCAS CPR, something which is not possible during manual CPR.
"Mechanical cardiopulmonary resuscitation (CPR) is strongly recommended if simple measures do not succeed in resuscitating the patient. We recommend that mechanical CPR is commenced after the first cycle of manual CPR.
An easy to-use, lightweight device that provides quality chest compressions in accordance with American Heart Association Guidelines for CPR (cardiopulmonary resuscitation) and assists rescuers in maintaining vital blood circulation in cardiac arrest patients, the LUCAS 2 Chest Compression System is simple to use, slips around a patient, can be applied to a cardiac arrest patient in under 20 seconds, and provides consistent quality chest compressions. The LUCAS is feasible for use in a majority of cardiac arrest patients in most settings and situations.
The LUCAS device not only mechanically pushes down on the chest (compression) but it also pulls up on the chest creating a suction (decompression) to pull blood back into the heart, which in turn maintains blood circulation better than manual CPR, increases operational efficacy, and improves the opportunities to save cardiac arrest patients. The push and pull system allows for a complete recoil of the chest to ensure the blood to can build up pressure that is essential to keeping the brain alive and functioning.
Additionally, the LUCAS device allows rescuers to concentrate on performing additional life-saving interventions without the limitations or difficulties of manual cardiopulmonary resuscitation (CPR), standardizes the quality of chest compressions adhering to the American Heart Association Guidelines for CPR depth, rate and recoil, and allows for effective CPR during patient movement and transportation, while improving rescuer safety.
A 49 -year-old male with no medical history calls 911 with chest pain and shortness of breath after working out at the gym. His 12-lead EKG demonstrates STEMI and while preparing to transport him he goes into cardiac arrest. His initial rhythm is ventricular fibrillation. He receives high-quality CPR, multiple shocks, Epinephrine, Amiodarone, and despite maximal interventions on scene, ROSC is never obtained. He is transported to the closest SRC and pronounced. I think we would all agree that this patient was too young to die.
Most shockable cardiac arrests are caused by a blocked coronary artery. The only way to definitively treat the cardiac arrest is by opening the artery up via stent placement in a cardiac cath lab. But how do we safely transport these patients from the scene of their cardiac arrest to the cath lab while maintaining high-quality CPR? This is where our new technology, the LUCAS (Lund University Cardiopulmonary Assist System) device, will help us save lives.
The LUCAS device is a mechanical CPR device that can provide uninterrupted chest compressions to the patient, allowing for consistent CPR during transportation of the patient. By providing high-quality CPR throughout transport and during treatment in the cath lab, cerebral and cardiac perfusion is maintained, allowing the best chance for not only survival but also a good neurologic outcome.
Soon, the LUCAS device will be available in select battalions to allow rapid transport of patients in cardiac arrest with refractory shockable rhythms to hospitals that can provide definitive care. With the LUCAS in place, the hospital will place the patient on extracorporeal membrane oxygenation (ECMO), which is an advanced type of heart-lung bypass machine that allows for oxygenation of the vital organs (i.e. the heart and brain). Once the patient is on ECMO, the LUCAS will be removed and the cardiologists can open up the blocked coronary artery by placing a stent and hopefully reverse the cause of the cardiac arrest.
The LUCAS device will be carried by selected EMS Battalion Captains, who will arrive on scene to assist with placement of the device and facilitate transport to the select SRCs that have the capability care for these complex patients. Through this pathway, we hope to not only save lives but match the success of other systems in which 50% of these patients walked out of the hospital neurologically intact and were able to return to their families and jobs.
CPR first aid consists of the application of rescue breathing as well as chest compressions. Compressions should be the initial step. If the person is skilled and confident, then mouth to mouth resuscitation can be carried out.
The technique assists in reestablishing the unconstrained flow of blood. CPR improves the chances of survival when it occurs on time and appropriately. The process is vital as it helps in averting tissue damage due to lack of oxygen.
The use of defibrillation is another essential process that should occur during an incident of cardiac arrest. It is the action of applying an electric current to restore the normal rhythm of the Sino-atrial node.
The LUCAS CPR device is a mobile tool for conducting chest compressions for an extended period. Its primary function is to help in saving a life during an incident of cardiac arrest. Its name stands for Lund University Cardiopulmonary Assisted System.
Traditionally, CPR was conducted by a bystander or emergency response services. However, in recent times, there has been a surge of mechanical compression devices that perform CPR. These devices run almost autonomously as they conduct the life-saving technique.
Compression is carried out by an automated machine that is powered electrically or utilizes air pressure. Statistics indicate that the tool can administer CPR first aid continuously and, at times, can even perform better than a person.
The LUCAS instrument comes in a case that you need to open to assemble the contents. It consists of a back plate and the upper compression part. During CPR, the victim is first laid on his or her back.
The victim is lifted gently by the shoulders, and the back plate is then placed underneath them. The patient is then placed on his back, and hand compressions are applied. These compressions are continued before that upper section is introduced.
The upper part of the instrument is then prepared and placed on the chest cavity of the victim. The back and front segments must fit into each other before the device starts. The compression pad must be located directly above the sternum.
It is essential to ensure that there is a backup battery on standby in case the one in use runs out. It helps in reducing interruptions in between compressions cycles. Defibrillation can happen as the machine runs. However, it is crucial to ensure the wires do not cross paths with the compression pad of the instrument.
In recent years there has been an upsurge in incidents of cardiac arrest. Cardiac arrest is mostly a result of a particular condition called arrhythmias. It is whereby there is an irregular heartbeat as a result of improper electrical signals.
The role of the AED is to send a corrective shock to the heart to restore the normal heart rhythm.The AED contains an inbuilt battery that creates the electrical signals. Chest plate electrodes and wires serve as a path for the electrical signals to pass to the victim.
Nowadays, you can locate these tools in most public spaces. AEDs come in diverse types and variants. All of them contain an instruction manual that gives the user all relevant data on the portable defibrillator. You should always read the manual before operating any AED.
When a cardiac incident arises, the first thing any respondent should do is to recognize the manifestations of cardiac arrest. Secondly, you should locate a phone and contact the emergency paramedic services and explain the situation.
