The following factors influence oxygenation on VVECMO with no native lung function
A. Pump flow rate
B. Recirculation
C. Cardiac output
D. All of the above
You note that there is a small trickle of blood in the pump head. The fastest action is
A. Clamp venous and arterial and, fix the tear with a connector
B. Replace the entire raceway segment
C. Clamp venous and arterial, open bridge stopcocks and fix the tear with a connector
D. Call the perfusionist
You are caring for a one-year-old on VA bypass. Pump flow is 1.0 cc/kg/min. Sweep gas flow is 60 % FiO2, 1.0 LPM. Ventilator settings are PIP 24 PEEP 6 rate 15 FiO2 .3. An ABG drawn from the radial arterial line reveals pH: 7.26, PaCO2: 62, PaO2: 75, and mixed venous saturation 81%. The most appropriate action would be to
A. Increase bypass flow
B. Increase the FiO2 of the sweep gas
C. Increase the sweep gas flow
D. Increase the ventilator rate
Management of VA-ECLS patients with a femoral artery cannula is likely to include
A. Frequent assessment of pedal pulses of the extremity with the cannula
B. Frequent assessment of the color and warmth of the foot distal to the cannula
C. Placement of distal arterial cannulae to improve perfusion of the extremity
D. All of the above
Cryoprecipitate is the blood product of choice for a patient on ECMO to treat
A. A low fibrinogen levels
B. Factor depletion
C. Hypovolemia
D. AT III deficiency
When assessing a patient’s oxygenation status on VVECMO, which of the following is the best indicator of adequacy of oxygenation?
A. Patient arterial saturation
B. Patient PaO2
C. Premembrane saturation
D. All of the above
The first thing to do if your bladder pressure stops the pump is
A. Give volume
B. Assess the cause
C. Decrease the bladder pressure
D. Decrease the pump flow rate
. All of the following are hemodynamically favorable features of VV-ECMO except for
A. Increased myocardial O2 delivery
B. Decreased afterload
C. Increased LV coronary pO2
D. Decreased preload
The perfusionist always needs to be present for ECMO decannulation
A. True
B. False
Increasing pump speed on VA-ECMO will usually
A. Increase pulmonary blood flow
B. Increase the patient’s mean blood pressure
C. Increase CO2 removal
D. Increase the bladder pressure
