What is the most important sign in a critically ill pt? Why? - ANSWER-Tachypnea Indicates metabolic acidosis w/ respiratory alkalosis compensation A pt misses dialysis for a few days and comes in with fluid overload. He's tachycardic and tachypneic. On physical exam, you find JVD, pulsus paradoxus (20 mmHg drop during inspiration), and HoTN (80/40) with distant, muffled heart sounds. Lungs are clear to auscultation. What is the dx? - ANSWER-Cardiac tamponade; obstructive shock If a pt ...

SVO2 Normal - >60% Low SVO2 - Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infection High SVO2 - increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesthesia, hypothermia CVP Normal - 2-6 High CVP - over hydration, cardiac tamponade, heart failure, pulmonary stenosis. Patient needs diuresis, vasodilation, or treatment for tamponade. Low CVP - hypovolemic shock for hemorrhage, fluid shift, dehydration. Pati...
