Overall, the aim of this experiment involved the examination of stimuli that triggered the bradycardia reflex, in relation to circulatory and physiological responses that occur in humans during dive reflex. Due to the different factors being generated the dive response was evoked to different extents. All variables including MAP, SV, CO, HR and TPR were monitored and varied (5). The basal measurements fell all within normal range, with respect to the conditions.
In cold water submersion, the main response was the initiation of the bradycardia reflex promptly after face submersion. The heart rate as indicated in figure 3 showed a significant decrease in levels. These results are shown to be as expected in relation to the bradycardia reflex (2). In fig 5, Cardiac output shows the same trend in relation to heart rate from fig 3, as heart rate slows down approximately 32% (fig 3). Total peripheral resistance was increased in fig 2, this is so that more oxygen can be improved for the vital organs. The increased levels of total peripheral resistance is also to allow more of the blood ...

    Of the two representations of the “Tell-Tale Heart”, the live action version is best. The live action was more accurate to the original story than the animated version was. The animated version was mostly for entertainment and got some facts wrong. In the live action, he killed the man in the same way and it had all the narrative of the story. The narrator wasn't Poe, like he was in the animated version. He disposed of the body the same and acted the way the character did in the original book. In the live action, the old man’s eye was completely covered by the film. He also panicked the same way as the book.

  • Cardiomyopathy Essay

    Cardiomyopathy, by definition, means the weakening of the heart muscle. The heart is operated by a striated muscle that relies on the autonomic nervous system to function. Cardiomyopathy is diagnosed in four different ways based on what caused the illness and exactly what part of the heart is weakened. The four main types of cardiomyopathy are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular dysplasia. One other category of cardiomyopathy that is diagnosed is “unclassified cardiomyopathy.” Unclassified cardiomyopathy is the weakening of the heart that does not fit into the main four categories.

    The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside natural heart abnormalities are those induced by chemical substances. The electrocardiogram is useful in showing how these chemicals adjust the electrical impulses that it induces.

    Individuals with AN keep their body in a state of starvation. Their body must function without the sustenance that it needs to continue functioning. Bradycardia is the most common heart arrhythmia for individuals with this disorder. As a result of the caloric deficit, the body tries to decrease cardiac work by reducing cardiac output. (Casiero & Frishman, 2006). The baroreceptor reflex is the body’s mechanism to regulate blood pressure through use of baroreceptors, which then transmits information to the brainstem. The vagal nerve receives this information, then sends impulses to the sinus node to slow the beat of the heart. (Kollai et al, 1994) A study published in the Oxford Heart Journal measured cardiac va...

  • Diving Reflex Lab Report

    When the subject submerged their face in 25 degree water, their heart rate decreased. It did not decrease very much because the water was at room temperature. It decreased more at 15 degrees and even more at 5 degrees. This was expected to happen because the diving reflex took place. The cold water puts the body is oxygen conserving mode and restricts the blood in your extremities. This is what reduces oxygen consumption which eventually lowers the heart

    Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise.

  • Near-Drowning in Pediatric Patients

    2212 Words  | 5 Pages

    There are an estimated 8,000 deaths per year in the United States from drowning. Near-drowning occurs anywhere from 2-20 times more frequently (for estimated 16,000-160,000 events per year)7. The definitions for drowning and near-drowning have for the longest time been very confusing to understand. Recent health officials have attempted to resolve some of this confusion by redefining drowning as “the process of experiencing respiratory insufficiency or difficulty following a submersion or immersion in a body of liquid.” Near-drowning has also been redefined as “survival from a drowning event which involved impaired consciousness or water inhalation for 24 hours or more”2. Both near drowning and near-drowning occur when someone experiences a submersion event. A submersion event is when someone, in this case a pediatric patient, experiences an unexpected submersion in water. When an unexpected submersion, regardless of water type (salt or fresh) occurs, the individual experiences breath hold, panic, and a struggle to resurface1. Humans, naturally, can only hold their breath for a short period of time. This prolonged breath hold results in hypoxia and eventually leads to involuntary gasping. As the individual attempts to gasp for air they sometimes aspirate7. This paper will attempt to look at the clinical presentation of a near-drowning patient who has suffered from a submersion event.

    If you put your hand on your upper left side of your chest the first thing you feel is your heart beating. Many people may not fully understand what our heart does, but they know they need it to survive in life. The heart only has one duty, and that is to pump blood throughout our bodies. The heart is just a muscle that plays a huge roll. There is a left and a right side to the heart and both do two different things in order to get the blood through our bodies. Our heart has a superior and inferior vena cava, right and left atrium, a tricuspid valve, right and left ventricle, a pulmonary valve, right and left pulmonary artery, left and right pulmonary vein, a bicuspid valve, and an aorta. Who ever knew our heart was so.. HELP

  • Essay On Myocardial Infarction

    1194 Words  | 3 Pages

    Oxygen was first admitted to the client with chest pain over 100 years ago (Metcalfe, 2011). Chest pain is a large bracket that can contain many different conditions, but for the purpose of this analysis it is focused manly upon a myocardial infarction. A myocardial infarction is mainly referred to as a heart attack, and occurs when one or more coronary arteries leading to the heart reduce or completely stop blood flow (Tuipulotu, 2013 ). Administering high concentrations of oxygen to patients with chest pain is now embedded in guidelines, protocols and care pathways, even with a lack of clear supporting evidence (Nicholson, 2004 ). High concentration of oxygen means that up to 60% is administered (Knott, 2012). More recent research has suggested that the use of oxygen in this scenario is unnecessary and can lead to unwanted side effects, especially in normoxic cardiac patients (Moradkham & Sinoway, 2010 ). The aim of this comparative analysis is to dismantle and understand both the benefits and risks of the commonly known practice of administration of oxygen to the client with chest pain. Through completing this analysis using recent and appropriate evidence a more improved practice can be given and understood.

  • Thermoregulation And Homeostasis

    888 Words  | 2 Pages

    Thermoregulation has a significant role in regulation of homeostasis. Nevertheless, its heat production and heat conservation mechanisms of major thermoreceptors are unknown. In response to cooling, temperature (core and oral temperature, skin temperature), cardiovascular (blood pressure, heart rate, stroke volume, cardiac output, total peripheral resistance, mean arterial pressure) and respiratory (minute ventilation, respiratory rate, oxygen consumption, metabolic rate and tidal volume) systems’ parameters are measured when we keep our subjects exposing to cold environmental temperature. Furthermore, to determine the dominant thermoreceptor when perceiving conflicting information, these temperature and cardiovascular parameters are measured repeatedly. Our studies showed that in response to cooling, core temperature was relatively constant. However, skin temperature dropped substantially due to vasoconstriction feedback.

  • Nervous Conditions by Tsitsi Dangarembga

    1269 Words  | 3 Pages

    The bridging of native traditions with modern imperial ways has a direct effect on the minds of Zimbabwean girls and women. Dangarembga drew inspiration for her title from the quote “the condition of the nation is a nervous one”, from Frantz Franon’s book Wretched of the Earth. The reader sees this idea of nervousness displayed within the female main characters of this novel. “ Its bad enough, when a country gets colonised but when the people do as well! That’s the end, really, that’s the end. (Nervous Conditions,150). This quote stated by Nyasha addresses how colonialism and imperialism are not just cultural, political and economical, but psychological as well. It infiltrates the minds of the citizens and their very cultural existence. The women in this novel are faced with the choice of embracing the British ways or running back to their Shona roots. No matter the choice they make, the Imperial control of the British Empire over Zimbabwe affects the minds of these women. The title of Dangarembga's novel, Nervous Conditions, alludes to the influence imperialism has on the minds of Tambu, Nyasha and Maiguru as they struggle to re-define themselves in a white man’s world.
