Neurogenic shock is shock Circulatory shock, commonly known simply as shock, is a serious, life-threatening medical condition characterized by a decrease in tissue perfusion to a point at which it is inadequate to meet cellular metabolic needs. As the blood carries oxygen and nutrients around the body, reduced flow hinders the delivery of these components to the tissues, caused by the sudden loss of the autonomic nervous system The autonomic nervous system is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness, and controls visceral functions. The ANS affects heart rate, digestion, respiration rate, salivation, perspiration, diameter of the pupils, micturition (urination), and sexual arousal signals to the smooth muscle Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit and multiunit smooth muscle. Within single-unit smooth muscle tissues, the autonomic nervous system innervates a single cell within a sheet or bundle and the action potential is propagated by gap junctions to neighboring cells such that the in vessel The blood vessels are the part of the circulatory system that transport blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from walls. This can result from severe central nervous system The central nervous system is the part of the nervous system that coordinates the activity of all parts of the bodies of bilaterian animals—that is, all multicellular animals except sponges and radially symmetric animals such as jellyfish. It contains the majority of the nervous system and consists of the brain and the spinal cord, as well as (brain The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is located in the head, protected by the skull and close to the primary and spinal cord The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain . The brain and spinal cord together make up the central nervous system. The spinal cord extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 4) damage. With the sudden loss of background sympathetic The sympathetic nervous system is one of the three parts of the autonomic nervous system, along with the enteric and parasympathetic systems. Its general action is to mobilize the body's resources under stress; to induce the flight-or-fight response. It is, however, constantly active at a basal level in order to maintain homeostasis stimulation, the vessels suddenly relax resulting in a sudden decrease in peripheral vascular resistance (vasodilation Vasodilation refers to the widening of blood vessels resulting from relaxation of smooth muscle cells within the vessel walls, particularly in the large arteries, smaller arterioles and large veins. The process is essentially the opposite of vasoconstriction, or the narrowing of blood vessels. When vessels dilate, the flow of blood is increased)[1] and decreased blood pressure In physiology and medicine, hypotension is abnormally low blood pressure. This is best understood as a physiologic state, rather than a disease. It is often associated with shock, though not necessarily indicative of it. Hypotension is the opposite of hypertension, which is high blood pressure. Blood pressure is the force of blood pushing against.

Symptoms A symptom is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured and signs A medical sign is an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination of a patient: circulatory The circulatory system is an organ system that passes nutrients , gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis (R00-R03 Asphyxia · Cough · Pleurisy · Sputum, 785 Olfaction : Anosmia · Hyposmia · Dysosmia · Parosmia · Hyperosmia)

Heart disease Heart disease or cardiopathy is an umbrella term for a variety of different diseases affecting the heart. As of 2007, it is the leading cause of death in the United States, England, Canada and Wales, killing one person every 34 seconds in the United States alone.[verification needed]

Tachycardia Tachycardia comes from the Greek words tachys and kardia (of the heart). Tachycardia typically refers to a heart rate that exceeds the normal range for a resting heartrate (heartrate in an inactive or sleeping individual). It can be very dangerous depending on how hard the heart is working and the activity. The upper threshold of a normal human/Bradycardia Bradycardia , as applied to adult medicine, is defined as a resting heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min. It may cause cardiac arrest in some patients, because those with bradycardia may not be pumping enough oxygen to their heart. It sometimes results in fainting, · Palpitation A palpitation is an abnormality of heartbeat that causes a conscious awareness of its beating, whether it is too slow, too fast, irregular, or at its normal frequency. The word may also refer to this sensation itself. It can be caused by ectopic beat, which is a more specific diagnosis Heart sounds The heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. This is also called a heartbeat. In cardiac auscultation, an examiner uses a stethoscope to listen for these sounds, which provide important information about the condition of the heart: Heart murmur (Systolic, Diastolic, Continuous) · Gallop rhythm A gallop rhythm refers to a rhythm of the heart on auscultation. It includes three or four sounds, thus resembling the sounds of a gallop (Third heart sound, Fourth heart sound) · Pericardial friction rub · Split S2 A split S2 is a finding upon auscultation of the S2 heart sound · Heart click With the advent of newer, non-invasive imaging techniques, the origin of other, so-called adventitial sounds or heart clicks has been appreciated. These are short, high-pitched sounds

Cardiovascular chest pain Chest pain may be a symptom of a number of serious conditions and is generally considered a medical emergency. Even though it may be determined that the pain is non-cardiac in origin, this is often a diagnosis of exclusion made after ruling out more serious causes of the pain

Vascular manifestations of heart disease (pulse In medicine, a person's pulse represents the tactile arterial palpation of the heartbeat. Sphygmology is a term from perhaps the 2nd century AD that roughly translates as "all that is known about the pulse". The pulse may be palpated in any place that allows an artery to be compressed against a bone, such as at the neck , at the wrist (): Pulsus tardus et parvus · Pulsus paradoxus In medicine, a pulsus paradoxus , also paradoxic pulse and paradoxical pulse, is an exaggeration of the normal variation in the pulse during the inspiratory phase of respiration, in which the pulse becomes weaker as one inhales and stronger as one exhales. It is a sign that is indicative of several conditions including cardiac tamponade, · doubled (Pulsus bisferiens, Dicrotic pulse, Pulsus bigeminus Pulsus bigeminus is a cardiovascular phenomenon characterized by groups of two heartbeats close together followed by a longer pause. The second pulse is weaker than the first. It is caused by premature contractions, usually of the ventricles, after every other beat, so called extrasystoles. It can be a sign of hypertrophic obstructive) · Pulsus alternans Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis · Carotid bruit · Cannon A waves
Vascular disease Cigarette smoking is the major risk factor Bruit Bruit is the term for the unusual sound that blood makes when it rushes past an obstruction (called turbulent flow) in an artery when the sound is auscultated with the bell portion of a stethoscope · necrosis Necrosis is the premature death of cells and living tissue. Necrosis is caused by factors external to the cell or tissue, such as infection, toxins, or trauma. This is in contrast to apoptosis, which is a naturally occurring cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always (Gangrene Gangrene is a serious and potentially life-threatening condition that arises when a considerable mass of body tissue dies . This may occur after an injury or infection, or in people suffering from any chronic health problem affecting blood circulation. The prime cause of gangrene is reduced blood supply to the affected tissues, which results in)
Myeloid In hematopoiesis, the term "myeloid cell" is used to describe any leukocyte that is not a lymphocyte. This terminology is frequently seen when classifying cancers, especially leukemia/blood Blood is a specialized bodily fluid that delivers necessary substances to the body's cells – such as nutrients and oxygen – and transports waste products away from those same cells
Shock Circulatory shock, commonly known simply as shock, is a serious, life-threatening medical condition characterized by a decrease in tissue perfusion to a point at which it is inadequate to meet cellular metabolic needs. As the blood carries oxygen and nutrients around the body, reduced flow hinders the delivery of these components to the tissues, Cardiogenic Cardiogenic shock is based upon an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively · Hypovolemic In physiology and medicine, hypovolemia is a state of decreased blood volume; more specifically, decrease in volume of blood plasma. It is thus the intravascular component of volume contraction (or loss of blood volume due to things such as hemorrhaging or dehydration), but, as it also is the most essential one, hypovolemia and volume contraction · Distributive Distributive shock is, as in hypovolemic shock, caused by an insufficient intravascular volume of blood. This form of relative hypovolemia is the result of blood vessel dilation. Septic shock is the major cause , but there are other examples as well (Septic Septic shock is a serious medical condition caused by decreased tissue perfusion and oxygen delivery as a result of infection and sepsis, though the microbe may be systemic or localized to a particular site. It can cause multiple organ dysfunction syndrome and death. Its most common victims are children, immunocompromised individuals, and the, Neurogenic)
Hyperaemia Hyperemia describes the increase of blood flow to different tissues in the body. It can have medical implications, but is also a regulatory response, allowing change in blood supply to different tissues through vasodilation Functional When cells within the body are active in one way or another, they use more oxygen and fuel, such as glucose or fatty acids, than when they are not. The blood vessels compensate for this metabolism by dilatation, allowing more blood to reach the tissue. This prevents deprivation of the tissue • Reactive
