For this discussion, I had to research what conditions can cause cardiac arrest and what time frame is CPR successfully initiated. I found out that some conditions with cardiac arrest are coronary artery disease, a heart attack, enlarged heart and congenital heart disease. Coronary artery disease is the most common of all. This is when the arteries become clogged with cholesterol and other waste products reducing blood flow. This makes it harder for the heart to conduct electrical impulses smoothly. A heart attach is really just a severe coronary artery but this leaves scar tissue which later effects the hearts rhythm. Enlarged heart is when the heart walls stretch and enlarge or thicken causing heart tissue damage. Congenital heart disease
1.Congestive Heart Failure also known as (heart failure) is a life threatening condition. Heart Failure is caused when someone has a weak heart. It usually happens when the bodies blood pump to the heart is not pumping blood to the heart correctly.
Christina Markevich 10/29/2015 Congestive Heart Failure What is Congestive Heart Failure? Congestive Heart Failure is something that occurs when the heart is no longer able to pump enough blood to the rest of the body, or when is just is not able to pump blood as well as it should. Some people happen to have either of these problems, some people have both.
Hypovolemic shock is the body’s response to a significant loss of fluids that disrupts the volume of blood within the body the body, causing disturbance in normally functioning systems. The most common cause of such response is from rapid loss of fluids, such as with hemorrhage, a sudden acute blood loss that can be externally or internally found throughout the human body (Tortura 781). Hypovolemic shock will then come secondary to hemorrhagic shock, the body’s initial response rapid blood loss as a way of trying to slow down or stop bleeding. When blood loss cannot be controlled with hemorrhagic shock, hypovolemic shock is then initiated (Kolecki, “Background”). However, significant fluid loss can also cause in relation to hypovolemic shock can occur in other ways, such as with excessive sweating, diarrhea, vomiting, or from a lack of fluid intake (Tortura 781).
sudden cardiac arrest is when the heart suddenly stops beating. Blodd stops flowing to the brain and other organs. Sudden cardiac arrest (SCA) causes death if not treated in minutes. The most common cause is an arythmia which is when rapid pulses causes your ventricles to quiver instead of pumping blood. Usually a life threatning arythima develops in a Person with a pre-existing heart condition such as: coronary artery disease, heart attack, or electrical problems in the heart.
In the CPR unit, I learned that CPR can save one’s life by following the exact steps. First, one has to shout to the other if he/she is okay. If they do not get a signal back, they have to call 911 as soon as possible and direct someone to get the AED or the automated external defibrillator which checks the heart rate and sends electrical shocks to the heart in order to try restore the heart rate. Before the ambulance and the AED arrives, one has to take off any clothes that are blocking the chest area. For women, the undergarment has to be taken off as well in order to have an effective CPR.
Questions: Provide a brief explanation of what orthostatic hypotension is, and identify the vital signs and their values that define orthostatic (postural) hypotension. Orthostatic hypotension occurs when an individual moves from a supine to a sitting or standing position. In an episode of OH, blood is pulled to the lower extremities by gravity. This pooling of blood stimulates the baroreceptors, sending a message to the vasomotor center of the brain and causing sympathetic nervous system activation. This results in an increased heart rate, which in turn increases the blood pressure and improves circulation back to the upper body .
1. What type of shock is John exhibiting signs of? [1 mark] Give a rationale for your answer and relate this to four [4] of John’s clinical symptoms and observations. [4 marks for clinical symptoms & 4 marks for observations] The type of shock John is exhibiting is cardiogenic shock.
Hypovolemic shock is an emergency condition in which severe blood or fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working. Hypovolemic shock refers to a medical or surgical condition in which rapid fluid loss results in multiple organ failure due to inadequate circulating volume and subsequent inadequate perfusion. Endothelium plays a critical role in vascular physiological, pathophysiological, and reparative processes.
23. Myocarditis infarction does permanent damage to part of the heart muscle due severe lack of blood flow. 24. Cardiodynia is when an individual experience pain in the heart. 25.
Cardiovascular Response to Exercise Introduction The cardiovascular system, comprising of blood vessels, the heart, and blood, responds predictably with regards to the increased exercise demands (Centers for Disease Control and Prevention 62). In a sense, a series of cardiovascular changes take place in response to physical exercise for providing enough blood supply to the constricting muscles, to dissipate the energy produced by active muscles, and to maintain the supply of blood to vital organs of the body such as the brain and the heart (Agarwal et al. CC06).
At the early stage of CHD, most people exhibit some symptoms or discomfort but some people might not have any symptom at all. Commonly, the symptoms of CHD include chest pain (angina pectoris), short of breath, dizziness and irregular heartbeat. In this study, there were eight risk factors being considered in the risk function of CHD. 1.2.1 Age and Sex In United States, CHD is the leading cause of death for both women and men. CHD is markedly more common in men than in women (Jousilahti, 1999).

HEART FUNCTION In general the function of the heart is pumping blood throughout the body and return them after lung organs cleaned. This means that the function of the human heart is as blood-pumping organs or tool in humans. At that time the heart provides blood and oxygen flowed throughout the body, as well as ridding the body of metabolic results (carbon dioxide). So as to carry out the functions of the heart collects oxygen-deficient blood from the rest of the body and then memompanya to the lung, by way of the blood in the heart taking oxygen and expel carbon dioxide.
It also has a very thick cardiac muscle wall (myocardium), this is because it needs a strong wall to be able to push the oxygenated blood to all areas of the body. The heart also contains (i) The tricuspid and bicuspid valves- these are situated between the atrium and ventricle. It is there to prevent backflow of blood from the ventricle to the atrium, it is a one way flow of blood.
Anatomy and Physiology of the Cardiovascular system and Circulatory systems The Circulatory System The Circulatory System is responsible for transporting materials throughout the entire body. It consist the heart, blood vessels, and the blood that circulates blood throughout the body. It delivers nutrients and other essential materials to cells, and removes waste products. The circulatory system is also known as the cardiovascular system. And without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment such as proper temperature and pH known as homeostasis.
