Everyone aspires for good health and vitality but there are several factors that prevent us from achieving this on a constant and periodic basis as we most desire. Encounters with various forms of diseases affect the normal way in which the body should function, taking away that…
Once these ischemic injuries set in, they leave patients with symptoms including high body temperature and other neurological dysfunctions. In such cases, the need to find protective interventions to deal with these aftermath effects becomes highly important and urgent. In this paper, one critical intervention to dealing with post adult cardiac arrest, which has effects like risk of ischemic injury to tissue, which is therapeutic hypothermia discussed for its effectiveness and efficiency as a care approach.
Neurological anatomy and physiology is discussed due to the relationship between neurological wellbeing and post cardiac arrest. As Arrich, Holzer, Havel, Müllner and Herkner (2012) note, “Good neurologic outcome after cardiac arrest is hard to achieve”. An understanding of the neurological anatomy and physiology will therefore make it possible to know why this is so and how this situation can effectively be tackled using therapeutic hypothermia. Quote (year) explained that neurological system comprises of two major components, which are the central nervous system (CNS) and the peripheral nervous system (PNS). Whereas the PNS is mainly made up of nerves that exit from the spinal cord, the CNS comprises the brain, the spinal cord, and the cranial nerves. Three major organs can therefore be anatomically and physiologically identified, which are brain, spinal cord and the vertebral column. Functionally, the brain is responsible for functions including “imagination, memory, speech, and limb movements to secretion hormones and control of various organs within the body” (Sehati, 2009). These functions are however made possible by the collective functioning of other cells, tissues and organs including brain cells, meninges, cerebrospinal fluid (csf), ventricles, brainstem, thalamus, cerebellum, lobes, cerebrum, hypothalamus, pituitary gland, basal ganglia, pineal gland, and cranial ...

When the heart’s sustenance is at risk, it cannot pump anymore blood to the human system and hence the body dies. The heart breakdown can have various symptoms in humans, but the extreme tension on this organ can invariably lead to cardiac arrest and finally death.
The lungs of the aging individual illustrate damaged exchange of gas, decelerated expiratory flow speeds, and a reduction in essential capacity. In addition, physiologic aging is also accompanied by decreased elasticity and compliance of the large arteries and aorta.
Other rhythyms and cardiac arrest complications/conditions which comprise less than 2% include subarachnoid hemorrhage or trauma, pregnant women, pediatrics, coma after near-drowning, hanging and other causes of asphyxia. About 60% of cardiac arrest survivors regain consciousness; of these, one-third experience irreversible cognitive disabilities.
The sinus node, atrium, and AV node are significantly influenced by autonomic tone (Saxena, P., Konstantinov, I. E., and Newman, M. A., 2007, p 60). Vagal influences depress the automaticity of the sinus node, depress conduction, and prolong AV nodal conduction and refractoriness in the tissues surrounding the sinus node; inhomogeneously decreases atrial refractoriness, slows atrial conduction and prolong AV nodal conduction and refractoriness (Reade, M.C., 2007, p 265).
The main significance of the study is to correctly ascertain the optimal duration of hypothermia, the optimal target temperature and the rates of cooling and rewarming. Its importance lies in the fact that many patients of cardiac arrest experience global ischemia that inflicts often irreparable damage to neurologic cellular mechanisms leading to very poor neurologic outcomes and, often, even mortality and vegetative existence.
Correspondingly, their studies provide sufficient evidence in the literature that supports the use of induced hypothermia to prevent and limit this anoxic brain injury (Hypothermia After Cardiac Arrest Study Group 2003; Bernard et al. 1997).
For therapeutic reasons, induced hypothermia is defined as the controlled lowering of a patient's temperature.
Advanced age can complicate prolonged mechanical ventilation, thus complicating the pulmonary dysfunction post cardiac surgical treatment. Postoperative pulmonary dysfunction is a significant clinical complication in patients undergoing cardiopulmonary bypass (CPB).
er, a nurse would really not have a sense of advancement in the execution of these skills, competence and knowledge if there are not concrete methodologies with which the duties they carry out are adequately measured. In this, Arcure and Harrison (2009) noted several means by
This is referred to as coronary heart failure of atherosclerosis.
