This article describes two case studies in which the AutoPulse® (AP) was used as an adjunct to manual chest compressions in prolonged CPR events. Resuscitation guidelines emphasize the importance of providing uninterrupted chest compressions during CPR. The AutoPulse with its patented load-distributing LifeBand® squeezes a wide area of the chest, spreading out the force of the compressions and helping to maximize blood flow. The LifeBand also allows full decompression for maximum coronary perfusion.
This case describes a cardiac arrest event on a 44-year-old male in which return to spontaneous circulation (ROSC) was achieved 48 minutes after continuous compressions with the AutoPulse. After 11 days of post-resuscitation interventions and care, the patient was discharged from the hospital with no neurological deficits.
This is a near-drowning case of a 26-year-old female who was pulled from the water with initial rhythm of VF, on whom CPR was immediately started. The AutoPulse was deployed for transport to the medical center and continued for 120 minutes after re-warming was initiated. The patient was discharged from the hospital 12 days after the accident with no neurological deficits.
In both of these cases, the patients had prolonged periods of apnea followed by spontaneous respiratory efforts after AutoPulse compressions where started. This finding signifies improved brainstem perfusion as a result of the AutoPulse generating near-normal circulation.
The difficulties of performing quality CPR for prolonged periods of time can adversely affect the chance for patients to achieve ROSC and long-term survival. The authors state that “In these cases, it would have been difficult or impossible to perform CC (continuous compressions) without the AP.” The AutoPulse allowed for prolonged quality compressions under difficult circumstances, resulting in improved outcomes.
