It started over a year ago when firefighter assistant Greg Anglin from the Melbourne Fire Department spontaneously visited our company. Chief Anglin, also the deputy chief of US Air Forces reserves at Langley Virginia, is known in all of his peers as a pioneer in the study of advanced technologies when it comes to saving lives and protecting people. Chief Anglin plays an important role in facilitating passive cooling of patients with heart failure or strokes, which will be used by the first responders in the field in response to the 911 call.
Regardless of whether the first respondents were sent by the fire department of the municipality or the private hospital emergency service, after resuscitation and stabilization of the patient with cardiac arrest for transportation, the procedural focus of the main angel was not to waste time and start using optimal temperature conducting cooling with New five-point cooling kit. Specifically designed for safe heat dissipation from a key point of view, the cooling packs are strategically placed in the armpits, groin, chest, head / neck, and as a stand for a stand under the patient, leaving the chest free and unobstructed for life monitoring. But he states that it should be pointed out here that conductive cooling should be a moderate temperature that could be well tolerated by the body (for example, not cold temperatures that give ice and gel packs), which could potentially aggravate the shock, which causes a further negative response. Rather, an average but cool temperature of about 55 degrees F or 13 degrees C would do more for the strategically abstract maximum heat load in a conductive manner and will begin the process of slowing down metabolic function as a precursor to therapeutic cooling in the hospital and preventing the hyperthermia from rebounding that follows cardio -respiratory arrest, which is believed to cause reperfusion injury. This is a combination of reperfusion injury and hyperthermia, which is associated with higher mortality and negative neurological outcomes, so avoiding rebound hyperthermia has a positive effect on the patient. During reperfusion, when oxygen is reintroduced after hypoxia, a sudden burst of oxygen free radicals (called neutrophils) can lead to the formation of other damaging species. These reactive types of oxygen further damage the cell membranes and adverse cellular function, so treatment time is critical, and slowing the body's mechanisms can be key in preventing cumulative damage.
Much has been written from studies by the Harvard University and the New England Journal of Medicine in newspapers across the US about the positive results of induced therapy of hypothermia in patients with cardiac arrest after returning to spontaneous circulation (ROSC) for at least 24-48 hours. For patients who are lucky enough to be transported to a hospital that is well equipped to effectively induce hypothermia, reducing core temperature to 30-32 degrees Celsius with slow methodological management after resuscitation, shows a high recovery success rate with a small amount of neurological damage, as the final output.
A recent study of 392 patients at Miller Medical School at Miami University, who were given only cold saline through a large vein, showed no benefit according to Dr. William O. Phill, Executive Dean for Clinical Affairs. New non-invasive cooling words used at sunset have the greatest possible success ratio.
The consensus among heart surgeons, GP doctors and medical workers, whom I have asked over the past few months, seems to agree that concomitant methodological cooling is inevitably restored ... the sooner the better. Although many agree that moderate induced hypothermia produces positive results, those who have tried the HTF Exotherm Passive Cooling Kit find many advantages in conductive thermal abstraction using a 55-degree cardan / stroke coolant kit for simplicity and simplicity to use. There are no pumps, batteries, tubes, electricity, and mechanical parts that may not work at critical times. “A handful of these optimal temperature cool packs, strategically placed on the patient, can also provide a calming effect for patients who are aware because they experience anxiety and stress, usually associated with heart attacks or stroke,” says Anglin. "This cooling kit has more positive effects." Hospitals that have tried these cool kits, including all head cooling, are in other applications from newborns to TBI (traumatic head injury), migraine headaches, and accelerated healing after orthopedic surgery or joint replacement.
How does this kit work? The HTF Exotherm Heart Cooling Kit is a simple, passive heat sink system. The heat transfer formula encapsulated in atomic packages consists of non-toxic, non-carcinogenic crystalline alkanes, which are extremely stable. Each mixture produces a substance that melts or hardens at a certain specified temperature and remains at that temperature for a specified time. Each mixed composition is then encapsulated in a proprietary copolymer film containing an antimicrobial additive specific to counteract the bacteria E-Coli and Staph. Placed in direct connection with a warm body, these cool packs quickly begin to safely simplify body heat. The secret of Exotherm's HTF lies in its ability to charge in minutes, even in ice and water, so practical use when there is no prevalence of electricity is a plus. The exotic nature of the technology in these packages is registered by the FDA, both the drug and the external vessel, and is so safe that they can be burned to fight infectious diseases in accordance with OSHA CFR 1910.
Acting as a heat sink, the cold temperature abstracts the excess body heat generated by normal metabolic activity and / or the temperature of the micro-environment. Blood transported through peripheral vessels and surrounding soft tissues displaces latent heat and becomes cooler, as more and more heat is abstracted from the surface. Here, recirculation of the cooling blood back through the venous fluid prevents additional concomitant hyperactivity that is necessary to meet the requirements of thermal control. Since colder blood continuously irrigates the cardiovascular system, less metabolic energy is required, slowing down the activity of vital vital forces (blood pressure, heart rate, pulmonary production of increased oxygen emissions), as well as latent heat of evaporation (sweating). Sweating decreases, cellular metabolic activity decreases, and less fluid from the electrolyte and precious minerals are lost, leading to a long-lasting fatigue ratio. Since no vascular constriction occurs, proper oxygen flow is maintained for optimal muscle function, brain activity, and CNS functions.
Recently, it has been recognized that the therapeutic / medical benefits of stable, controlled temperature compounds demonstrate excellent results when used as body cooling devices or therapeutic cooling devices. True thermal management. The recent overwhelming recognition in the medical community has successfully demonstrated that the effective use of optimal temperature cooling (heat generation) for acute and chronic injuries, post-operative recovery and long-term diseases will significantly shorten the rehabilitation time and return to the function of the affected area,
Unlike frozen water or gels, cold-temperature alkanes (45F - 60F) displace energy at a constant temperature during their transition from solid to liquid; therefore, the melting and freezing points of these alkane mixtures are the same. As you know, water absorbs energy faster because of its high heat transfer properties (heat of reaction). Water, when it turns a phase into ice, absorbs energy at a speed of X and displaces that same energy at the same speed X when it passes from a solid (ice) to a liquid (water). Alkanes, on the other hand, absorb energy at a rate of X when the phase transitions from its liquid state to its phase solid state, but they displace this absorbed energy at a much lower rate when moving from their stressed state to their liquid state. In this case, the slow release of energy, when it is associated with the cooling of the body of a person or animal or for use in cryotherapy, this rate of energy release can reach five times the speed of water for the same volume of alkanes. prolonged cooling cycle than can be tested with ice or gels of the same volume or weight.
Johnny Hartley, Angel Flight EMT and Firefighter tried many 55F HTF body chassis, including 3 miles per day jogging and lifting weights that put on a fire protection reactor cooling jacket to reduce body heat loads when working with high heat . Hartley reports a recovery of at least 2 minutes and returns to the original level of his HR and BP when working with a rehabilitation vest. He reports that simplicity and ease of use reveals that the heart cooling kit takes up little space and can be sterilized for reuse without offering a mess, unlike ice bags. Since space is such a bonus in aviation ambulances, when they are charged, they can be twisted and stored in a dry insulated cooler and left for 24-48 hours, taking up very little space. This cardiac cooling kit is currently being tested in the UK and the USA with very promising feedback.
In the US, more than a million Americans have heart attacks every year. If the first responders can begin to enter therapeutic cooling within a few minutes after answering the 911 call, imagine the success rate for preventing neurological damage and recovery.
