Deciding when hemodynamic monitoring is appropriate. How will the data affect your diagnostic or therapeutic approach?

Hemodynamic data can be used to differentiate a variety of cardiopulmonary disorders, including right ventricular dysfunction, massive pulmonary embolism, and precapillary pulmonary hypertension. In patients with acute pulmonary edema, low-output states, or shock, hemodynamic measurements can help guide therapy; they also provide a precise estimate of a patient's response to vasoactive or inotropic drugs. Consider a flotation catheter for patients with complicated MIs, critically ill patients with multiorgan or major organ dysfunction, and high-risk cardiac patients undergoing surgery.
