Visual summary
Review the precipitant, home blood pressure, medication access, cardiac evaluation, and kidney status after the acute event.
Text version
Rapid pressure change
Pulmonary edema can arise from abrupt increases in filling pressure and afterload, sometimes without a large preceding increase in total body fluid.
Recognize instability
Acute breathlessness, hypoxemia, diaphoresis, severe hypertension, or ischemic symptoms require urgent assessment and stabilization.
Look for precipitants
Consider ischemia, arrhythmia, valve disease, medication interruption, kidney dysfunction, and renovascular disease in appropriate recurrent presentations.
Stabilize the circulation
Respiratory support, afterload treatment, and diuresis must be selected according to blood pressure, perfusion, congestion, and the underlying trigger.
Do not assume one mechanism
A hypertensive redistribution syndrome differs from profound volume accumulation or cardiogenic shock. Repeated reassessment guides the balance of therapies.
Prevent another episode
Review the precipitant, home blood pressure, medication access, cardiac evaluation, and kidney status after the acute event.
