Blood Pressure Imbalances and Circulatory Shock

A normal blood pressure is necessary for healthy bodily functions. But, homeostatic imbalances may abruptly change the blood pressure, causing severe clinical conditions.

For instance, hypertension is characterized by sustained high blood pressure of 130 over 80 mm Hg or higher. It's often caused by obesity, alcohol consumption, stress, and genetic predisposition.

On the other hand, chronic hypotension, below 90 over 60 mm Hg, can result from dehydration, blood loss, or sepsis.

Circulatory shock is another clinically significant condition marked by inadequate blood flow and reduced ability to supply nutrients and oxygen to tissues. There are four main types of shock.

Hypovolemic shock arises from substantial blood loss due to acute hemorrhage during traumatic injuries.

Vascular shock happens due to sudden vasodilation, leading to rapid and severe hypotension. 

In cardiogenic shock, the heart fails to pump enough blood, often due to damage from a heart attack or ischemia. 

On the other hand, obstructive shock blocks or obstructs the blood flow. It is most commonly caused by pulmonary embolism or cardiac tamponade.
