WebMar 4, 1997 · Septic shock is a form of distributive shock most commonly caused by infection with gram-negative bacteria. 1 2 The hallmark of septic shock is marked peripheral arteriolar vasodilation, which results in low systemic vascular resistance, high cardiac output, severe hypotension, and inadequate tissue perfusion. Therapy typically includes … WebSep 26, 2024 · Shock refers to the inadequate perfusion of tissues due to the imbalance between oxygen demand of tissues and the body’s ability to supply it.

WebThe Compensatory stage (Stage 2) is characterised by the body employing physiological mechanisms, including neural, hormonal, and bio-chemical mechanisms, in an attempt to reverse the condition. As a result of the acidosis, the person will begin to hyperventilate in order to rid the body of carbon dioxide (CO 2 ).
WebJul 1, 2004 · In the peripheral circulation, a reduction in total peripheral vascular resistance (the ‘systemic vascular resistance’ or SVR) is the norm in sepsis, 8 and it is the reflex response to the resulting hypertension that causes the increased cardiac output seen in the ‘classic’ picture of septic shock. Treatments aimed at increasing the SVR ... WebShock is a state of organ hypoperfusion with resultant cellular dysfunction and death.

WebIn other words, resistance in cardiovascular system is generally expressed as R units (Reynold’s number), which are obtained by dividing the pressure in mm Hg by flow in ml/sec. For example, if the mean arterial pressure is 90 mm Hg and the left ventricular output is 90 ml/sec, the total peripheral resistance is. 90 mm Hg/90 ml/sec = 1 R unit.
