During bedside assessment of a patient with a PAC, the respiratory therapist in the MICU notices a dampened waveform on the monitor of the arterial line. To restore the graphic to normal, the RT should FIRST:

What will the MAP be if the systolic blood pressure is 93 mm Hg and the diastolic blood pressure is 60 mm Hg?

BONUS: What is considered the hallmark of cardiac contractility?

Mr. Jim Bean is a 69 YO male who has undergone CABG X4 and is being hemodynamically monitored is currently on mechanical ventilation. Based on the following recorded parameters, what is the the patient’s oxygen consumption?pH 7.37, PCO2 48 torr, PO2 240 torr, SaO2 95% on 100% O2Hb 15.2 g/dLPB 750 torrPvO2 51 torr (SvO2 49 torr)QT 4 L/min

Where is the PAC placed, if the waveform on the monitor is “B”

What position is the Swan-Ganz catheter, if it is displaying the waveform on “C”?

Which of the following conditions are commonly associated with an inadequate expiratory time?I. airtrappingII. Auto-PEEPIII. appropriate flow rateIV. low mean airway pressure

An increase in pulmonary capillary wedge pressure is seen in patients with all of the following conditions except:

Which of the following are signs and symptoms of severe left ventricular failure?I. High systemic blood pressure with increased cardiac outputII. DyspneaIII. Skin cool and clammyIV. Fine crackles

BONUS: A patient’s CaO2 is 20.1 vol% and the CvO2 is 14.6 vol%. The oxygen consumption (VO2) is 220 mL/min. What is the patient’s cardiac output?
