Dopamine may cause rapid heart rate and arrhythmias, and is only recommended in combination with norepinephrine in those with slow heart rate and low risk of arrhythmia. In the initial treatment of low blood pressure in septic shock, the goal of vasopressor treatment is a mean arterial pressure (MAP) of 65 mm Hg. [10]
People with sepsis need preventive measures for deep vein thrombosis, stress ulcers and pressure ulcers, unless other conditions prevent such interventions. [4] Some might benefit from tight control of blood sugar levels with insulin .
The severity of hemorrhagic shock can be graded on a 1–4 scale on the physical signs. The shock index (heart rate divided by systolic blood pressure) is a stronger predictor of the impact of blood loss than heart rate and blood pressure alone. [11] This relationship has not been well established in pregnancy-related bleeding. [12]
Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1 ] [ 2 ] It is one of four categories of shock , a condition where there is not enough oxygen -carrying blood to meet the metabolic needs of the cells ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
Pulse pressure begins to narrow, but systolic blood pressure may be unchanged to slightly decreased. [3] Class 3: Volume loss from 30% to 40% of total blood volume, from 1500 mL to 2000 mL. A significant drop in blood pressure and changes in mental status occur. [3] Heart rate and respiratory rate are significantly elevated (more than 120 BPM).

Both SIRS and sepsis could ultimately progress to multiple organ dysfunction syndrome. In one-third of the patients, however, no primary focus can be found. [1] Multiple organ dysfunction syndrome is well established as the final stage of a continuum: SIRS + infection → sepsis → severe sepsis → Multiple organ dysfunction syndrome.
