LifeVest Provides Protection for Patients at Risk of SCA The LifeVest is worn by patients at risk for sudden cardiac arrest (SCA), providing protection during their changing condition and while permanent SCA risk has not been established. The LifeVest allows a patient’s physician time to assess his/her long-term arrhythmic risk and make appropriate plans. The LifeVest is lightweight and easy to wear, allowing patients to return to their activities of daily living, while having the peace of mind that they are protected from SCA. The LifeVest continuously monitors the patient’s heart and, if a life-threatening heart rhythm is detected, the device delivers a treatment shock to restore normal heart rhythm. The LifeVest is used for a wide range of patient conditions or situations, including following a heart attack, before or after bypass surgery or stent placement, as well as for those with cardiomyopathy or congestive heart failure that places them at particular risk. Additional products on display from ZOLL include: The AutoPulse® Non-invasive Cardiac Support Pump, which provides automated CPR chest compressions when the heart is no longer effectively circulating blood due to ventricular fibrillation or cardiac standstill. It features an easy-to-use, load-distributing LifeBand® that squeezes the entire chest, improving blood flow to the heart and brain during SCA. The AutoPulse may offer a significant advantage over manual CPR, moving blood more consistently than human providers. The device delivers high-quality, uninterrupted chest compressions to maintain myocardial and cerebral perfusion. Additionally, it offers the benefit of freeing up clinicians to focus on other life-saving interventions. The R Series® Code-Ready® defibrillators are designed to extend simple, smart and ready defibrillation to every hospital department through advanced, cost-effective solutions for resuscitation. The original R Series ALS, and the newer R Series Plus, which also has both AED and ALS capabilities at the touch of a button, offer See-Thru CPR®, an industry-unique filtering technology that allows professional rescuers to view a patient’s underlying cardiac rhythm by filtering CPR artifact during resuscitation efforts.
