Vascular Disorders

Cardiogenic Shock Nursing Management, Pathophysiology, Interventions 

 Vascular shock occurs when blood volume is normal, but vasomotor tone is suddenly lost, causing extreme vasodilation. The massive vasodilation event leads to a drastic and dangerous drop in blood pressure. Vascular shock can be triggered by anaphylaxis, septic shock, and certain bacterial toxins. Hypovolemic shock is a result of large-scale blood loss; it is the most common form of circulatory shock. Cardiogenic shock is a result of heart failure or damage; it can result from multiple myocardial infarcts (heart attacks). 

 Cardiogenic shock is most likely to result from __________.

Hypertension - Overview (Causes, Pathophysiology, Investigations, Treatment)

 A sustained blood pressure of 140/90 is indicative of hypertension. 

 Hypertension is defined physiologically as a condition of sustained arterial pressure of __________ or higher.

Hypovolemic Shock Nursing, Treatment, Management, Interventions

Hypertension - High Blood Pressure

 Circulatory shock results in inadequate blood flow to meet tissue needs when blood vessels are inadequately filled and blood cannot circulate normally. 

 Any condition in which blood vessels are inadequately filled and blood CANNOT circulate normally is called __________. 

 In vascular shock, blood volume is normal and constant but there is an abnormal expansion of the vascular beds, resulting in a huge drop in peripheral resistance, causing blood pressure to fall rapidly. 

 Loss of vasomotor tone that results in a huge drop in peripheral resistance is known as __________.
