1 Describe the principle of operation of the pulse oximeter.Ģ Identify conditions that can influence the accuracy of pulse oximetry readings.ģ Describe the differences among CO-oximetry, oxygen saturation (SaO 2), pulse oximetry, oxyhemoglobin saturation (SpO 2), and the patient’s clinical condition.Ĥ Discuss the normal components of a capnogram.ĥ Give examples of pathophysiologic conditions that can alter the contour of the capnogram.Ħ Identify the normal value for arterial-to-end-tidal partial pressure of carbon dioxide (P(a-et)CO 2.)ħ Describe the various components of a volumetric CO 2 tracing, and discuss how these types of tracings can be used to assess gas exchange during mechanical ventilation.Ĩ Explain the theory of operation of transcutaneous PO 2 and PCO 2 monitors.ĩ List the clinical data that should be recorded when making transcutaneous measurements.ġ0 Describe the major components of an indirect calorimeter.ġ1 Provide the respiratory quotient (RQ) value associated with substrate utilization patterns in normal, healthy subjects.ġ2 Discuss some clinical applications of metabolic monitoring in critically ill patients.ġ3 Briefly describe devices that are used to measure airway pressures, volumes, and flows during mechanical ventilation.ġ4 Calculate mean airway pressure, dynamic compliance, static compliance, and airway resistance.ġ5 Identify pathological conditions that alter lung compliance and airway resistance.ġ6 Describe how changes in airway resistance and respiratory system compliance will affect the results of measurements of the work of breathing.ġ7 Define the pressure-time product, and discuss its application in the management of mechanically ventilated patients.
