Cardiogenic Shock Cardiogenic Shock is defined as decreased cardiac output and evidence of tissue hypoxia in the presence of adequate intravascular volume Cardiogenic shock can acute or chronic disorders that effect the function of the heart in supplying adequate tissue/organ perfusion. Stages of shock Compensated Shock: The body homeostatic mechanisms take over and compensate for the poor perfusion. Hypotensive Shock: The body is no longer able to compensate. Patient start to show sign of distress. Heart rate elevated, hypotension, organ dysfunction, altered mental status. Irreversible Shock: Patient will start to have organ damage that is irreversible, bradycardia, severe hypotension. Patients have a poor likelihood of survival. Clinical …show more content…

If Cardiac Output is compromised than you will have low tissue/organ perfusion. Causing the patient to go into cardiac shock. Systolic and Diastolic Function Systolic function is the ability of the ventricles to eject blood out of the chamber. Systolic function can be altered from certain pathology such as CHF, ischemia, cardiomyopathy or heart disease. Diastolic function is the ability of the ventricles to relax and fill properly. If the chamber is unable to relax and fill properly than this can cause systolic dysfunction. When evaluating systolic and diastolic function it is extremely important to obtain images of wall motion, wall thickness, chamber size and ventricular end diastolic pressure.

Defects When evaluating for Cardiogenic Shock patients may have many different congenital heart defects. You need to obtain images that evaluate color Doppler on possible shunting abnormalities. Hypoplastic Left heart Obtain all views that visualize the left heart Images that evaluate size and functions pf all valves and chambers Find any other abnormalities that have effected the heart Coarctation of the Aorta Suprasternal notch is the optimal window to evaluate coarctation of the aorta Color Doppler should be applied to look for turbulent flow Place PW descending down the Aorta you should see a increase in velocity Look for any dilation in the aorta after the coarctation Congenital heart defects Aortic Valve Stenosis: Evaluate images looking at the Aortic valve SAX at AOV level to obtain image with planimetry of the AOV valve M-mode to look for a eccentric closure line which indicates a bicuspid aortic valve Thicken cusps will have a decreased aortic cusp separation An essential tool for evaluating Aortic valve stenosis is to obtain peak velocity with CW, images need to be obtain in apical and suprasternal notch.
Pedof should always be attempted to get highest velocity additional view is right sternal boarder (placing patient in right lateral decubitus) Cardiomyopathy: Dilated chambers Decreased systolic and diastolic function Thin walls Possibility of a thrombus Summary Patients that come in in cardiogenic shock during there echocardiogram need to be evaluated in a whole looking for any abnormalities. Diastole dysfunction, systolic dysfunction, any possible shunting issues, aortic stenosis, coarctation of the aorta or

Also, hypoxia, which is a lack of oxygen, is another pathological physiological outcome of sepsis as less oxygen is reaching the tissue; this is due to the fact that there is less oxygen in the blood.
Hypovolemic shock specifically disrupts the cardiovascular system from a significant loss of blood volume that causes blood pressure to deplete and oxygen delivery to cells to slow. A victim entering into hypovolemic shock will experience three sequential stages as the body attempts to maintain homeostasis. These stages are named compensated, decompensated, and irreversible (Wang
Septic shock is a condition and/or state of hypoperfusion that derives from another condition called sepsis; Sepsis the infection of the bloodstream. In order to acquire septic shock one must obtain an infection of the bloodstream. Any type of pathogen can cause that infection. The main factor is bacteria and while fungi and viruses have been known to be able to cause septic shock the occurrence is much more rare than through bacteria.The cause of septic shock lies within
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
Power can be defined as the ability to influence or outright control the behavior of people. A variety of different things can drive power, including both knowledge and experience. Power in most cases is needed to establish authority. In today’s country, the United States government has a lot of power. It has so much power that even American citizens are beginning to complain about it. Having all this power and authority has allowed the government to make decisions quicker. However, by making decisions faster, some mistakes can be made and innocent people can be convicted. This point is directly exemplified when using two New Yorker articles, “Surviving Solitary” and ‘A Shot to The Heart.” Both articles consist of results produced quite
In a healthy individual receiving a general anaesthetic, the anaesthetist must be aware of the causes and treatment of acute onset AF, both intra-operatively and peri-operatively. Patients with AF often develop a decline in left ventricular performance and other hemodynamic instabilities including reduced diastolic filling and tachycardia mediated cardiomyopathy1, all of which can reduce cardiac output and pose difficulties for the anaesthetist.
The treatment priorities of the registered nurse upon admission to the emergency department are as follows; within the first 10 minutes of Mr. Bronson’s arrival to the emergency department begin a 12 lead ECG. Assess Mr. Bronson’s vitals heart rate, blood pressure, respiratory rate, oxygen saturation, and administer oxygen 2-4 liters via nasal cannula (Sen, B., McNab, A., & Burdess, C., 2009, p. 19). Assess any pre hospital medications, and if he has done cocaine in the last 24 hours. At this time, the nurse should assess Mr. Bronson’s pain quality, location, duration, radiation, and intensity. Timing of onset of current episode that brought him to the emergency room, any precipitating factors, and what relieves his chest pain.
Systolic and Diastolic are the two types of heart failure. Systolic dysfunction occurs when the heart muscle doesn't contract with enough force, which means there is less oxygen-rich blood that is pumped throughout the body. Diastolic dysfunction is when the heart contracts normally, but the ventricle does not relax properly, reducing the amount of blood that can enter the heart and raising the blood pressure in the lungs. Heart failure is a progressive condition and can worsen over time. There are four stages of heart failure that have been classified by the AHA and ACC.
Elaborate: The cardiac cycle of the heart is divided into diastole and systole stages. Diastole refers to the period of relaxation experienced by the atria and ventricles. Systole is the contraction of the atria and ventricles. The pattern of blood flow starts in the left atrium to right atrium then into the left ventricle and right ventricle. During its course, blood flows through the mitral and tricuspid valves. Simultaneously, the right atrium is granted blood from the veins through the superior and inferior vena cava. The job of the superior vena cava is to transport de-oxygenated blood to
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
Cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other
Shock is defined as an insufficient delivery of oxygen to the tissues. To break it down, this means that the amount of oxygen that is required for the body is not being delivered. There are numerous types of shock. The five major types of shock include: cardiogenic shock, obstructive shock, distributive shock, neurogenic shock, anaphylactic shock, psychogenic shock, hypovolemic shock, and respiratory insufficiency shock. The three main causes of shock include reduced blood volume, acute heart conditions, and poor vessel function (RightDiagnosis.com). Reduced blood volume often comes from blood loss; and some examples of acute heart conditions often include heart attacks, arrhythmias, and trauma to heart (Medicine Net). The type of shock that will be discussed in this paper is septic shock which is a type of distributive shock.
