Over the last decade, the routine use of both invasive and noninvasive monitoring devices has been instituted for the administration of most anesthetics. The following statement(s) is/are true concerning monitoring of the surgical patient.
A. A pulse oximeter reading will reflect changes in PaO2 only below 80 mm Hg
B. Monitoring of end tidal CO2 will reflect changes in ventilation but not cardiac output
C. Intermittent, noninvasive systemic blood pressure monitoring using an oscillometric blood pressure cuff has essentially replaced clinical measurement by auscultation
D. Pulmonary arterial catheter monitoring is generally reserved for critically ill patients with significant left ventricular dysfunction
