Final Exam Review Flashcards
Mixed venous oxygen saturation is measured at __________ while central venous oxygen saturation is measured at the __________.
Pulmonary artery right atrium
When does the mitral valve close?
at the beginning of isovolumetric contraction
A procedure that requires opening the left heart to air requires more than one vent to adequately de-air the heart before separation from the CPB… T/F
true
Does parasympathetic stimulation increase myocardial oxygen demand?
No
the frank starling law talks about…
LV end diastolic muscle length and LV muscle function
T/F As ventricular volume increases, a larger force from each muscle cell is prequired t produce any given intraventricular pressure.
True
If your patients O2 delivery is 1000ml/min, and their O2 consumption is 500 ml/min, What is their SvO2
50%
A stress test on a 45 yr old male shows lateral akenisis, what EKG leads are going to show the changes?
V5, V6
The patient has an end diastolic volume of 200ml. The patient’s end systolic volume is 100ml. Heart rate is 50 BPM Does this patient have severe LV dysfunction?
No
T/F In a patient with atrial fibrillation, the measurement of stroke volume variation by the FloTrac transducer is not accurate, but the cardiac index and stroke volume measurements are accurate.
True
When placing a PA catheter and you notice that you have 45cm of catheter in the patient, yet you continue to see an RV waveform. Based on your understanding of PA catheterization, you can assume that:
The cath is most likely curling in right ventricle
Venous cannulation for CPB can be accomplished via (2)
the right atrium, the vena cava
Your patient is undergoing intraabdominal heated chemotherapy infusion following exploratory laparotomy and tumor debulking under a balanced general anesthetic. Your core body temperature is 38.7 degrees C. You notice a cardiac index of 3.1 L/min and and SvO2 of 51%. Your knowledge of hemodynamic monitoring allows you to realize that the patient’s oxygen consumption is ________________, with the most likely cause being ________________.
increased; hyperthermia
T/F a CVP of 12 ALWAYS means the patient has an adequate fluid volume status.
FALSE BITCHES!!!!!
Your 47 y/o female patient is undergoing laproscopic hemicolectomy. Within 5 minutes after insufflation of the peritoneum with carbon dioxide, your hemodynamic parameters are as follows. Of note, the patients starting hemoglobin was 12.1 mg/dl & you have experienced no blood loss, you are ventilating with positive pressure and tidal volumes of 8ml/kg, PEEP 5, and the patient is in NSR. ABP 83/43 CI 1.9 SVV 20 ScvO2 63% The next most appropriate intervention should be to:
give a 500ml bolus of fluids
Typical ejection fraction is ______%.
60-65 40
The EKG correlates to coronary anatomy. Inferior wall changes are most likely seen in which leads?
II, III, aVF
You are performing a pre-op evaluation on a 69 y/o male patient who is scheduled for an elective inguinal hernia repair the following day. The patient states he underwent coronary angiography 6 months ago and two drug-eluding stents were placed in his LAD artery. The patient states he has no anginal symptoms and a exercies tolerance of 7 METs. The most appropriate way to proceed in this case is?
Cancel this elective case because national guidelines state patients with drug eluding stents should wait over 1 year before stopping anti-platelet agents to undergo elective surgery
T/F In a normally functioning heart, there is a moment when the aortic valve and mitral valve are open at the same time.
False
T/F CVP is a reliable indicator of volume responsiveness (increase in cardiac output in response to a fluid challenge).
False
Please use the picture below to answer question. Match the wave to what it represents. This is a Central Venous Pressure Waveform in NSR.
X wave

Downward displacement of the ventricle during systole
In a hyperkalemic patient, you would expect to see _____________on ECG.
peaked t waves
What is the equation for EF?
EDV-ESV/EDV × 100
T/F
The total amount of O2 dissolvd in your plasma contributes in a large way to O2 delivery.
False
