What is the aorta?
The calculation to determine oxygen delivery.
What is cardiac output (CO) x oxygen content (Cao2)?
A patient who underwent corrective heart surgery who is unable to wean from bypass. ECMO candidate yes or no?
What is YES?
A daily one of these is used to check for bleeding in the brain
What is a head ultrasound?
3 possible complications of ECMO therapy.
What is bleeding, infection, mechanical problems?
This separates the right atrium from the right ventricle
What is the Tricuspid Valve?
Affects the ability to consume oxygen.
What are metabolic demands?

What is NO?
This is done several times through the day to check the function of the ECMO machine and how it is oxygenating the body.
What is an arterial blood gas?
Upon recognition of an emergency, the patient must be separated from the ECMO circuit by.
What is clamping the Venous line first, open the bridge and then clamping the Arterial line (VBA)?
These two vessels bring de-oxygenated blood to the heart from the body.
What is the superior and inferior vena cava?
The transport of oxygen to the tissues to be used for energy production.
What is oxygen delivery (DO2)?
3 year old near drowning who arrives to the ED with a fast and thready pulse, unable to maintain her airway, and whose status shows nearing a possible code situation.
What is Maybe - need more information?
Checked every hour, more frequently if out of range or if heparin is turned off.
What is ACT?
This is the most common mechanical complication during ECMO.
What is clots in the ECMO circuit?
Trace the blood flow through the four chambers of the heart.
What is deoxygenated blood enters the right atrium, then flows into the right ventricle, (pulmonary artery to lungs to the pulomnary vein) then into the left atrium into the left ventricle then into the body?
Three components that work together to support oxygenation.
What is pulmonary gas exchange, hemoglobin and cardiac output?
4 year old motor vehicle accident victim, ejected from vehicle, arrived at the hospital with blown pupils, decerebrate posturing, and in hemodynamic shock.
What is NO?
Lab done to monitor PT, PTT, fibrinogen, anti-thrombin III and FSP.
What is Coagulation studies?
If this happens, the pump flow must be stopped immediately to prevent upward movement and flow into the patient.
What is air in the circuit?
Three shunts in the fetal circulation which allow oxygenated blood to flow to the heart and brain.
What are the ductus venosus, foramen ovale, and the ductus arteriosus?
A reflection of the balance between oxygen delivery and oxygen consumption.
What is SVO2 or venous oxygen saturation?
35 week gestational age newborn with severe meconium aspiration syndrome weighing 2500g. Head ultrasound shows a grade 1 bleed on the left.
What is YES?
How often Na, K, Cl, HCO3, iCa and glucose are checked.
What is every 12 hours or as needed?
A rare mechanical complication but a possibility if this becomes damaged or cracked.
What is tubing rupture?
