Medical emergencies

During transport, you are caring for a 57‐year‐old female with a history of congestive heart failure who was recently treated for acute pulmonary edema. Suddenly, her blood pressure drops to 80/50 mm Hg and her heart rate increases to 120 beats per minute. A bedside ultrasound reveals a hyperdynamic, underfilled left ventricle with no signs of pericardial effusion. What is the most appropriate next step in her management?

The ultrasound findings and clinical signs indicate hypovolemia likely from overdiuresis or ongoing fluid losses. In this scenario, the patient’s heart is hyperdynamic due to low preload. The correct intervention is to cautiously administer an IV fluid bolus to restore intravascular volume while carefully monitoring for potential fluid overload.
