The low blood pressure seen in those with sepsis is the result of various processes, including excessive production of chemicals that dilate blood vessels such as nitric oxide, a deficiency of chemicals that constrict blood vessels such as vasopressin, and activation of ATP-sensitive potassium channels.

COVID-19 infection may trigger the development of high blood pressure, new research shows. Researchers found that COVID-19 infections had a much higher association with hypertension than influenza.
Bacteremia is clinically distinct from sepsis, which is a condition where the blood stream infection is associated with an inflammatory response from the body, often causing abnormalities in body temperature, heart rate, breathing rate, blood pressure, and white blood cell count. [42]
Septic shock is a potentially fatal medical condition that occurs when sepsis, which is organ injury or damage in response to infection, leads to dangerously low blood pressure and abnormalities in cellular metabolism. The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defines septic shock as a subset of sepsis ...
Processed Foods Raise Blood Pressure. Yes, many ultra-processed foods (think doughnuts, candies and hot dogs) are not the best choices for our health. However, there are a surprising number of ...
When it comes to developing high blood pressure, Covid-19 might play an outsized role, a new study says. The report, published Monday in the medical journal Hypertension, found that more than 1 in ...
The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
Documented goals for blood pressure include a reduction in the mean arterial pressure by less than or equal to 25% within the first 8 hours of emergency. [7] If blood pressure is lowered aggressively, patients are at increased risk of complications including stroke, blindness, or kidney failure. [6]
