The device is about the size of a fist and can be affixed to either a facemask or an endotracheal breathing tube during CPR. It enhances the intrathoracic vacuum that forms in the chest during the chest recoil phase of CPR by temporarily sealing off the airway between breaths and preventing unnecessary air from entering the chest (timing-assist lights on the device will aid the rescuer in ventilating the patient at a proper rate). The vacuum that is created pulls blood back to the heart, doubling the amount of blood that is pulled back by conventional mouth-to-mouth/chest compression CPR, according to clinical studies, which also show that blood flow to the brain is increased by 50 percent. In sustaining proper blood flow to the heart and to the brain, ResQPOD increases the likelihood of survival and decreases the likelihood of neurological disorders.
ResQPOD is being used by emergency medical technicians in cities all around the country, including Boston, Houston, Indianapolis, Miami, and Oklahoma City, as well as Hartford, Connecticut; Kansas City, Missouri; Raleigh, North Carolina; and Toledo, Ohio. In some cities, it has reportedly increased the number of cardiac arrest patients delivered alive to the hospital by as muchas 50 percent. At Cypress Creek Emergency Medical Services (EMS), a large medical care organization serving more than 400,000 residents in the greater Houston area, ResQPOD has become a standard of care. Overall resuscitation rates climbed to nearly 50 percent since the organization began deploying the device in 2005, boosting hospital admission rates from 26 percent to an astounding 38 percent.
"These results are gratifying, and we applaud the entire Cypress Creek EMS organization for their advanced emergency medical service care and their ability to turn around the dismal statistics that surround cardiac arrest," noted Advanced Circulatory Systems' Lurie.
In its secondary commercial applications, Advanced Circulatory Systems is offering ResQPOD to improve circulation in patients suffering from orthostatic intolerance and general low blood pressure. These secondary uses alsoapply to individuals who undergo dialysis treatments and may experience a drop in blood pressure, as well as those who go into shock after severe blood loss.
Outside of the traditional hospital setting, the company is investigating the beneficial impact ResQPOD could have on wounded soldiers in the battlefield who may have lost a great deal of blood and are in danger of going into shock.
Advanced Circulatory Systems is also harnessing the physiological principles discovered during its research collaboration with NASA to develop another promising technology: an intrathoracic pressure regulator for patients requiring ventilation assistance because they are too sick to breathe on their own.
