Chapter 10: SHOCK Flashcards
Anaphylactic Shock
A type of distributive shock that occurs when a person reacts violently to a substance to which he/she have become sensitized
Anticoagulant
Medications that prevent blood from clotting. AKA blood thinners
Cardiogenic Shock
Shock caused by inadequate function of the heart, pump failure, resulting in poor cardiac output
Distributive Shock
Shock resulting from widespread dilation of the small arterioles, venules, or both
Fainting
Loss of consciousness that results from a lack of blood flow to the brain.
May occur suddenly, resulting from the temporary dilation of the body’s veins and pooling of blood in those vessels.
AKA Syncope
Hypovolemic Shock
Shock caused by an inadequate amount of fluid or volume in the circulatory system
Neurogenic Shock
Distributive shock that is caused by disruptions of the CNS
Obstructive Shock
Caused by a blockage that prevents oxygenated blood from reaching vital organs
Perfusion
The circulation of blood within an organ or tissue in adequate amounts to meet the cells’ current needs for oxygen, nutrients, and waste removal
Peripheral Vascular Resistance
The tightening of the smaller-diameter blood vessels in the extremities, enabling increased blood flow to the vital organs
Pulmonary Embolism
A blood clot that becomes stuck in and block the pulmonary artery.
AKA thromboembolism
Sepsis
A serious medical condition caused by the presence of pathogenic organsims or their toxins in the blood, leading to a systemic inflammatory response.
Septic Shock
Type of distributive shock that is caused by sever systemic infection
Shock
inadequate perfucsion causing cellular and tissue hypoxia due to reduced oxygen delivery.
Stroke volume
The ammount of blood pumped out of the left ventricle into the aorta during one heart beat
