The HI-MAP protocol is a structured ultrasound assessment used in critical care to evaluate patients with undifferentiated hypotension. This rapid, systematic approach helps identify the cause of shock, guiding immediate clinical management. It typically assesses the heart, IVC, lungs, and abdominal aorta, providing crucial insights into cardiac function, volume status, and potential sources of bleeding…

Fluid responsiveness in critical care, particularly through ultrasound, refers to the heart's ability to increase its stroke volume and cardiac output in response to a fluid bolus. This dynamic assessment is crucial for guiding intravenous fluid administration, helping clinicians differentiate between patients who will benefit from additional fluids versus those who may be harmed by…

In Critical Care, the Passive Leg Raise (PLR) is a quick, reversible bedside maneuver used to assess a patient's fluid responsiveness. By elevating the patient's legs, venous return to the heart is temporarily increased, simulating a fluid bolus. An improvement in cardiac output (measured by ultrasound, e.g., VTI or IVC collapsibility) indicates the patient is…
