Document Summary
The qsofa score is a bedside prompt that may identify patients with suspected infection who are at greater risk for a poor outcome outside the intensive care unit (icu). It uses three criteria, assigning one point for low blood pressure (sbp 100 mmhg), high respiratory rate ( 22 breaths per min), or altered mentation (glasgow coma scale<15). Systolic dysfunction: inability of the heart to pump blood. Shock can be classified as low flow (cardiogenic and. Shock: a syndrome characterized by tissue perfusion and impaired cellular metabolism resulting in an imbalance between supply and demand of oxygen and nutrients hypovolemic shock) or distributive (septic, anaphylactic, and neurogenic shock). Cardiogenic shock: when either systolic or diastolic dysfunction of the pumping action of the heart results in compromised cardiac output (co) forward. Diagnosis = lab, ecg, echocardiogram, chest radiography. Hypovolemic shock: when there is a loss of intravascular fluid volume and the remaining fluid is inadequate to fill the vascular space.
