Therapeutic hypothermia

Introduction Therapeutic hypothermia, also called targeted temperature management, is a procedure that lowers the body's temperature in order to treat a heart that has suddenly stopped working (cardiac arrest). This procedure is used in emergency situations. During cardiac arrest, the brain cannot get enough oxygen. The brain also starts to swell, which can damage or kill brain cells. Therapeutic hypothermia helps reduce swelling in the brain. It also slows down the body's metabolism and allows the

Induction Phase. This is the first phase of therapeutic hypothermia. The aim of this phase is to deliberately reduce the patient’s core body temperature to a degree where mild hypothermia is induced. The target temperature for this phase of therapeutic hypothermia is roughly 32-34 °C, although the exact target temperature varies between healthcare facilities. The induction of mild hypothermia can be achieved through a variety of different methods, including ice packs, cold saline infusion, external

Theraputic Hypothermia Hypothermia, defined as a core body temperature less than 95 °F(35°C) occurs when heat loss exceeds the body’s heat production. (Ruffolo p.47) Thermal stability in humans depends on the body’s ability to adapt to changes in internal and external temperatures. Heat is transferred throughout tissues and fat, and is released at a rate directly related to the temperature of the environment through radiation, conduction, convection, and evaporation.

There are numerous studies on ways to increase the survival rates and overall outcomes of these patients. Therapeutic hypothermia is one of the new and upcoming studies for post cardiac arrest care. It is used in various EMS agencies worldwide. It has shown significant improvements in patient’s outcome and reduced neurological deficits. There are specific indications for when therapeutic hypothermia can be used. Once indicated there are three phases involved which include induction, maintenance, and

mammal lacks the diving response, then it I smore likely that they may drown because of their body not being able to properly respond to the lack of oxygen. The reactions observed could have also been the result of either the body preparing for hypothermia or simply responding to the cold- water shock. Cold water shock is the body’s response to being suddenly exposed to cold-water. Cold water shock also causes vasoconstriction by causing the blood vessels in the skin to close; both increase the resistance

Hypothermia for Cardiac Arrest Introduction Survivors of cardiac arrest often suffer from neurological damage when oxygen to the brain is depleted. This ischemia to the brain can cause lesions or damaged areas; which can effect any part of the body that is controlled by that portion of the brain. Decreasing the body temperature of a patient has shown to be effective in decreasing the amount of damage to the brain. Therapeutic hypothermia may be a reasonable treatment for patients following cardiac

* Patients with mild hypothermia (93.2º F-96.8º F [34º C-36º C]) have shivering, lethargy, confusion, rational to irrational behavior, and minor heart rate changes. * Moderate hypothermia (86º F-93.2º F [30º C-34º C]) causes rigidity, bradycardia, slowed respiratory rate, blood pressure only by Doppler, metabolic and respiratory acidosis, and hypovolemia. Shivering diminishes or disappears at temperatures ≤86º F (30º C). * Severe hypothermia (<86º F [30º C]) is a severe

Newborns are born with physiological challenges. They have physical immaturity that is not able to function like an adult or child can. When newborns exit their mother’s womb, the newborn is welcomed into this new environment. The new environment can be unsafe, frightening, and cold for them. The transition from fetal to newborn life can be full of instability. Skin-to Skin Contact (SSC) is placing the newborn on their mother’s bare chest covered with a blanket. SSC warms a cool baby naturally

Homeostasis 3.4 Hannah Miller Introduction My investigation is about Homeostasis. Homeostasis is maintaining a physiological system in a higher animal to maintain co-ordinated responses. It tries to maintain the environmental changes, and a condition of balance or equilibrium within its internal environment. Homeostasis is the process of keeping everything constant. The higher animal I have chosen is Humans. The reason why I have chosen Humans

and overcame it and how you succeeded in this process. My educational fear in the past was during my first week off ICU orientation, I was assigned an admission from the ER of a post cardiac arrest middle aged patient who was placed on a therapeutic hypothermia. I verbalized to the Charge Nurse of being hesitant to accept the admission since I’m fresh off orientation. She told me “this would be a good experience for you”. I want to keep good positive impression to my colleague being a new nurse of
