OXYGEN DEBT & OUTCOMES
This is the time frame within which oxygen debt must be "paid back" to decrease postoperative complications.
8 HOURS
According to Habib et al. 2003, the lowest hematocrit on CPB is associated with this many major complications. (a number)
What is 10 (reopening, bleeding, MI, cardiac arrest, stroke, coma, prolonged ventilation, IABP, renal failure, MOF)?
This is the abbreviation for Acute Kidney Injury
AKI
This is the formula for calculating oxygen delivery (DO₂).
CaO2 x Blood Flow x 10
This measurement of oxygen is what we use for our main number in goal directed perfusion

Something you might say after being on bypass for ten hours.
DO2i, I want to go home
These three patient groups were identified in Shoemaker's oxygen debt study based on their perioperative outcomes.
Survivors w/o complications, survivors w/complications, non-survivors
This percentage represents the cutoff value for lowest predictive hematocrit according to combined data studies.
26%
Stage One AKI is defined as this percentage increase in creatinine or an increase greater than this mg/dL value (percentage or mg/dL)
150-200% or >.3 mg/dl
This SvO₂ percentage threshold indicates the patient is nearing the oxygen-dependent zone.
Answer: What is <68% (or O₂ER >30%)?
Where you might keep your quarters

Type of stitch used to keep cannulas in place.
Coin (Purse) string sutures
This study from 1999 showed improved survival with dopexamine compared to this intervention group.
According to the Cleveland Clinic study, PRBC transfusion to treat anemia increased mortality by this percentage
What is 77%?
According to the presentation, renal oxygen consumption is second only to this organ
Heart
The formula for calculating oxygen consumption (VO₂) uses this equation.
What is (CaO₂ - CvO₂) x Blood Flow x 10?
When you are deprived of an essential molecule after surgery
& a Question they might ask about your expenses and salary when looking to get a mortage
Oxygen (Debt) to income ratio
According to the York Study, goal-directed therapy is most effective when using these two types of interventions together.
What are fluids and inotropes?
In the multi-center retrospective study of 1,444 patients, anemia plus PRBC transfusion increased AKI to this percentage
What is 29%?
This percentage represents the renal oxygen extraction rate, making it very sensitive to oxygen delivery mismatc
10%
According to Ranucci's 2015 study, even this small reduction in prime volume can make a significant difference in outcomes.
Answer: What is 150 mL?
Where you blood empties after the it leaves the patient

Venous (Reservoir) dogs
This is what happens to cells when oxygen debt is never repaid during the perioperative period.
What is cell dysfunction and death?
This critical value in mL/min/m² represents the aerobic/anaerobic threshold for oxygen delivery according to Ranucci's study.
272 ml/min/m2 (280 is acceptable lol)
This partial pressure range in mmHg describes the outer medulla oxygen levels in normal conditions.
10-20 mmHg
According to Hayward 2022, the critical DO₂ threshold for pediatric patients during CPB is this value.
Answer: What is 350 mL/min/m²?
This are the combined drugs and fluid you start out in your pump before bypass
